How to make a working rocket model

Launching model rockets is quite an interesting sight. The rocket, releasing huge puffs of smoke, hissing, takes off to a height of 300-400, or even more meters, then - cotton, a small parachute opens and it sways smoothly, falls to the ground.

The shape of the rocket model can be very different, reminiscent, for example, of the well-known Gird, Vostok, Soyuz missiles, the Surface-to-Air anti-aircraft missile, this is domestic production, or foreign ones - Veronica (French), Astrobi ”, “Aerobi-high”, “Saturn” (American), “Meteor” (Polish) and others, possibly of their own design.

For a rocket to take off higher, it must be as light as possible. Therefore, the material for the manufacture of rocket models is paper (drawing paper), balsa, light woods, thin long-staple paper, polystyrene, etc.

Rocket models are made single-, double- and multi-stage, i.e. with one, two or more engines. Let's consider a simpler option, a single-stage one.

The process of manufacturing a rocket model (see figure) must begin with the body. We take a slipway (tube or round rod) with a diameter of 30 mm and wind one layer of drawing paper onto it. We glue the body with silicate glue. Bonding width 10 mm. We roll up the hull on the slipway.

The glued body must be removed for a few minutes so that the glue dries. After this, we plant the hull on the slipway and leave it to dry completely.

At the dried body, we cut off the remains of its length on the slipway to the desired dimensions according to the figure. We level the place of gluing with the body with fine-grained sandpaper, taking care not to wipe it until brightening or holes, and we cover it with one layer of thin long-staple paper.

Then we cover the body of the rocket model with enamel, when the first layer dries, we cover the body with three more. After the enamel has completely dried, as the body will no longer smell like it, we wrap the upper metal guide ring with threads and remove the model body from the slipway.

We make the upper guide ring from a wire cut to one millimeter or from an ordinary paper clip with a slightly larger section than the guide that will be used to launch this rocket model.

In the lower part of the hull, three stabilizers made of balsa, 3 mm thick, are glued, which we make in a streamlined shape. We glue the stabilizers on both sides with one layer of thin long-staple paper.

They are glued to the body at an angle of 120°. The gluing place must be strengthened by paper corners 15x40 mm in size, glued to the body of the rocket model and stabilizers with thick enamel.

We make the lower guide ring from paper and glue it to one of the stabilizers, and we wind the upper guide ring (metal) over the bottom one. In this case, it is necessary to ensure that the centers of the metal and paper rings lie on the same straight line.

The heart of any rocket, of course, is a jet engine, in our case, a solid propellant one. When burning, the fuel emits a large amount of gases, which create jet thrust flying out of the nozzle. Such engines are made in pyrotechnic workshops and used to be on sale, now I don’t know. I would not recommend making them yourself, because. it is not safe, although in some aircraft modeling circles, experienced specialists did this.

To fix a standard factory jet engine in the body of the rocket model, which runs on solid fuel with an impulse of up to 10 n / s, we make a sleeve 25 mm long, with an outer diameter of 30 mm and an inner diameter of 20.5 mm from NHV foam. We glue the sleeve into the lower part of the body with silicate glue.
When working with polystyrene, in no case should you use nitro-glues and nitro-paints, because. they dissolve it and you can ruin the part.

In the upper part of the body of the rocket model, the main part is inserted - a fairing made of PVC foam on a lathe. It should enter the body of the model freely so as not to bother the parachute drop. We glue the fairing with long-fiber paper, also smeared with silicate glue. A round rubber shock absorber of an aircraft model is passed through the fairing, one end of which is tied to the upper metal ring, and the other to the stabilizer. Parachute straps tied to the middle of the shock absorber.

We make the parachute dome from thin long-staple paper and is a polyhedron inscribed in a circle with a radius of 750 mm, to which slings of threads No. 10 are glued, which have a length of 1500 mm. We make a wad for pushing out a parachute from PVC foam plastic with a size of 30x30 mm in the form of a cylinder and glue it with paper.

In order for the rocket to be stable in flight, it is necessary to pay special attention to the location of the center of gravity (CV) and center of pressure (CP). The CV should be three centimeters above the center of pressure. The correct alignment is achieved by the location of the parachute inside the body of the model, or by additional loading of the bow, for example, with lead or by making it from wood, you can reduce the weight of the engine, but this is more problematic.

It is clear that we can change the CV along the axis of the rocket, but how to find the CV? To do this, you need to cut out, from cardboard, a life-size flat contour of the rocket model and find the center of weight of the contour using the balancing method. At this point, the center of pressure of the future rocket will be located, it is somewhere in 33% of the bottom. Then transfer this point to the real model. Here is such a primitive method.

For orientation - the flight weight of a single-stage rocket model is approximately 80 grams, a two-stage one - 120 grams.
It is necessary to launch such a rocket on a launch pad, which is equipped with a guide pin on which the rocket is put on, and an electric start (electric ignition) from a distance of at least 10 meters.

As you can see, making such a rocket is not difficult, the main thing is to get an engine for it. You can improvise a little, change, for example, the shape of the fairing, or stabilizers, paint it in your own way, but in order for the rocket to be stable in flight, the above calculations must be observed.

Now a little about the electric ignition of the rocket, you can make it yourself from nichrome or tungsten wire with a diameter of 0.1-0.2 mm. Suitable, for example, from an old soldering iron. We take a piece of such a wire and wind it on a thin needle (up to 1 mm), the resistance should be around 2 ohms. We power such a fuse from 4.5-6 V batteries or accumulators. It is better to use a new fuse for each launch.
That's all, good start.

This rocket is an ordinary toy, only it can fly according to the same principles as a real rocket. This is great entertainment for the whole family, and will also be a chic end to any holiday.

You will need

Instruments

• Utensils for fuel.
• Porcelain mortar and pestle.
• Mallet.
• File.
• Drill.

For body

• Starch.
• Iron smooth straight wire with a cross section of 3-5 millimeters.
• Thick cotton threads.
• Elastic band for models.
• Wooden stick with a diameter of 3 mm and a length of 6 cm.
• Silk ribbon 5-80 centimeters wide.
• Bright waterproof paint.
• Steel wire 1 mm.
• Butter.
• Glue.
• A piece of soft wood.
• Newspaper.
• Drawing paper.

• A nail with a diameter like a hole that is drilled into a sleeve.
• 12 gauge cardboard sleeve without primer.

For fuel

• Sulfur 10.
• Charcoal 28%.
• Saltpeter potassium 62%.

Instruction

1. Create a fuel mix: mix all the ingredients in the right proportions. Create a mixture for the wick by mixing sulfur and saltpeter at the rate of one part sulfur and nine teas of saltpeter.
2. From the side of the capsule attachment, you need to drill the metal part of the sleeve. Then remove the capsule fasteners.
3. Drive a nail into the board. It should protrude from the board by two centimeters. Grind the protruding end so that it has smooth conical contours. Sharpen the sharp end a little.
4. Now you need to remove all metal filings. Put the sleeve on the nail with a metal part and pour mixed fuel into it ¾ of the height. Using a round wooden stick, compress the fuel by tapping lightly with a mallet.
5. Cut out a circle from food paper so that it is slightly larger than the inner diameter of the sleeve. They should close the layer of fuel. On top of the partition that turned out, pour the fuel mixture with a layer of half a centimeter and then glue the sleeve on top with a layer of thin paper. This charge is designed to release a parachute.
6. Wrap a large diameter stick with newsprint. Fix with glue and let dry. Then lightly soak a layer of newspaper with oil and wipe it off.
7. On the resulting blank of drawing paper, wind the tube, two turns thick. Coat the coils well with glue. Dry this tube on a stick. Then remove the layer of newspaper, it is no longer needed.
8. Make a fairing softwood rockets. This is a cork six to seven centimeters long, the upper end of which ends in a rounding and descends into a cone, and the lower one, one and a half centimeters long, is tightly inserted into the upper part of the paper tube. You have a fairing and a rocket body.
9. Whatman paper make at least three stabilizers. These are the triangles that must have petals in order to connect with the rocket. Stabilizers are attached to the rocket body with glue. From the end of the fairing, which is located in the rocket body, fasten a bracket or a metal ring with an internal diameter of half a centimeter, which is made of steel wire. Close the ring. It is necessary for attaching a parachute.
10. Insert the engine sleeve into the bottom of the rocket. It should be inserted tightly and removed as needed. If the motor is tight, glue an extra 3 cm wide paper ring on the inside of the case. Now dry the entire body and paint with waterproof paint in any color you like (bright is better).
11. Create a parachute. The diameter of the dome is fifteen to twenty centimeters. Use a parachute for the rocket. Attach one end of the ribbon to a wooden stick. Attach a loop to the ends of the stick from a thread ten centimeters long. Tie a piece of aviation rubber ten centimeters long to one end of the tape. Tie the end of the rubber around the wire ring that is put on the fairing. Using a regular thread for it, make an additional mount. Tie another ten centimeters long thread to the end of the fairing. Also tie a piece of aviation rubber to it, and five centimeters of an ordinary thread to it. Fasten this thread on the inside of the rocket three centimeters from the upper end of the tube. You can launch it through the entire rocket, creating holes in it and pasting it with paper rings for strength.
12. Now stow your parachute. Starting from the free side, wind the tape into a roll. From the outside, press the roll with a stick to which the parachute is attached. Slide this roll into the rocket body. From above put a thread and a tape of fastening to a fairing. Close the rocket with a fairing.
13. Create a Starter Device. Cut one hundred and twenty centimeters of iron wire. On a piece of Whatman wire, glue two cylinders with a diameter slightly larger than the diameter of the wire and one centimeter long. It is necessary that the rings slide freely along the wire. The resulting rings must be fixed with strong glue on one longitudinal line of the rocket body. One ring should be fixed at the junction of the stabilizers with the body, and the other - in the upper part, approximately one centimeter from the fairing. It is necessary that the rocket slides freely along the wire. From any wire, wrap a restrictive ring around the rocket at a distance of fifty centimeters from one of the ends. She should not go further than this ring. This side of the wire must be stuck into the ground.
14. Create a fuse. You can take a ready-made fuse from a firecracker or firecracker, however, the length may not be long enough. Create a stop. To do this, take a cotton thread and fold it six times. You should end up with a length of eight centimeters. Weld the paste. Moisten the thread with starch paste. All of it must be dipped in a composition that differs from the composition of the fuel in that it must be without coal. Then dry.
15. Before starting, you must insert the engine into the housing. Before you insert the engine, you need to insert the wad. A piece of foam can serve as a wad. Bend the cord at one end, and then insert this end into the nozzle. READY!!!

note

• Making a rocket motor is a safe process, but do it carefully. You can use a ready-made rocket engine.
• When you pour the fuel mixture on the partition, you do not need to compress it.
• The length of the Whatman tube is about 45 centimeters.
• A rocket without a parachute cannot be used because it is dangerous.
• The parachute can be of any design. It can be made from fabric or paper. Better make more lines.
• When launching a rocket, move at least 10 meters away from it.

• You can use nitro enamel or pentaphthal paint.
• You can make a stabilizer from 1 mm plywood.
• Arrange the stabilizers symmetrically, glue neatly and firmly.
• We recommend using poplar or linden wood
• Wood is being replaced by hard foam.
• You can use whatman paper or half paper.
• Any oil will do, even vegetable oil.
• Glue is better to use nitrocellulose or BF.
• We recommend using tissue paper.

Haven't you ever wanted to become an astronaut and fly into space aboard a rocket? To become an astronaut, you need to spend many years in training and training. In the meantime, you can make and launch your own homemade rocket in the yard, which, thanks to our instructions, you can make yourself.

To make a homemade rocket you will need:

A4 sheet of paper

From 35mm film (with a lid that fits inside the opening of the jar rather than over the circumference of the jar)

adhesive tape

Scissors

Water

An antacid effervescent tablet (an antacid used to calm an upset stomach)

Eye protection: sunglasses or goggles

How to build a homemade rocket?

1. Make an enlarged copy of the rocket so that it fits on a sheet of A4 paper. Cut out the template details.

2. Remove the lid from the film can. Using adhesive tape, glue the large one cut from the template to the jar. Make sure the opening end of the can is right on the edge of the paper.

3. Now twist the paper around the jar to make a cylinder and glue it adhesive tape. The jar should be at the bottom of the cylinder.

4. Take the nose cone piece. Glue the ends together with duct tape to form a tapered shape. Glue the cone to the top of the paper cylinder.

5. Take the stabilizer templates and fold along the dotted lines. Glue to the rocket body. Your rocket is now ready to launch!

6. Take your homemade rocket outside and wear goggles to protect your eyes.

7. Turn your homemade rocket upside down and fill the jar halfway with water.

8. Drop half an antacid tablet into the container and close the lid quickly.

9. Set up your homemade rocket on a launch platform, such as a concrete path or paved area. Step back and wait. In a few seconds, yours will take off!

How a homemade rocket takes off and works

When the tablet is placed in a jar of water, it begins to dissolve and hiss. Hissing produces more gas inside the jar, but with the lid closed, it cannot escape. After all, something has to happen! Therefore, the bank shoots the lid. and gas rush outward down, pushing the can, together with the rocket attached to it, up.

Real rockets work on the same principle. Instead of water and an antacid tablet, the rocket's fuel tank contains a mixture of various fuels that causes an explosion. The explosion erupts from the bottom of the fuel tank, forcing the rocket into the air.

The first rocket to launch anything into space was the R-7 launch vehicle. With its help, on October 4, 1957, Sputnik-1 was launched in the USSR - the first artificial Earth satellite (AES)

In this material, we will present an overview of the video on the manufacture of a rocket launcher, as well as rockets for this very rocket launcher.

So, we need:
- PVC pipe;
- two plastic bottles;
- scotch;
- paper;
- a lighter for a gas stove;
- sandpaper;
- hacksaw;
- heat-resistant silicone.

The first step is to make a combustion chamber. The author suggests making it from a bottle. Since the bottle can break due to the power of the explosion, it needs to be sealed second. We take a clerical knife and cut out the top of the bottle.

Cut out the lower part as well, leaving the middle one.

We pass to the middle part, which we cut along to get one strip.

The resulting strip will act as a sealant, so we put it on the second bottle and wrap it well with tape.

Next, we need to cut a piece of PVC pipe and attach it to the plastic bottle cap. To do this, cut out a piece from the pipe and process the cut with sandpaper.

Next, cut out the top of the lid with a clerical knife.

We also process with sandpaper.

Slightly sharpen the tip of the tube so that it fits into the lid.

We glue the cover to the pipe with heat-resistant silicone.

Next, you need to connect a lighter for a gas stove to the ignition chamber. To do this, disassemble the lighter.

We remove the upper part in which a spark forms and expose the wires.

We take two self-tapping screws, and screw them into the bottom of the bottle. We wrap two wires on self-tapping screws, which we connect to the wires in the lighter.

After that, we isolate the wires, thus obtaining a system for supplying a spark to the ignition chamber.

It should be noted that at first the author screws in the screws in the middle part of the bottle, which, according to him, is not so effective when using alcohol as a fuse. This is explained by the fact that when pouring alcohol into a bottle, it is at the bottom. Alcohol vapors are also highly concentrated at the bottom, so the fuse in the middle is not as easy as at the bottom. The rocket launcher is ready, you can start making rockets. To do this, we will use paper, adhesive tape and a piece of PVC pipe, which is attached to the lid.

We take paper and wrap it around the PVC tube.

We glue the paper with tape to fix it in a wrapped state. Close the open end of the tube with paper and tape.

Since the paper is light, you need to make the rocket heavier. To do this, it is enough to wrap it with electrical tape.

We cut out small triangular stabilizers from a piece of cardboard and glue them on the rocket with a glue gun. Stabilizers are needed in order for the rocket to fly smoothly.

On this, the manufacture of rocket launchers and rockets can be completed. In the end, we note that it is necessary to pay special attention to the tightness of the ignition chamber, since if it is violated, there will simply be no rocket launch.

The whole process is shown in great detail, and the expediency of each action is clearly and easily explained. A special point that is emphasized is the safety of manufacturing and further launch, and this is extremely important for both adults and children.

How to make a space rocket with your own hands from paper at home

At home, from the most ordinary paper, you can make a real space rocket with your own hands. The work is not too difficult, but requires accuracy and attention. School-age children can easily cope with this task on their own, and kids from kindergarten will need a little help from educators, parents or older brothers or sisters.

Necessary materials for a space rocket made of paper

• paper
• insulating tape
• scissors
• glue gun (or PVA glue)
• empty plastic tube from a ballpoint pen

Step by step instructions for making paper rockets at home

1. From a sheet of paper, cut out two pieces of the same length and a width of approximately 5 centimeters.
2. Attach a small piece of electrical tape to one piece of paper and wrap the plastic tube from a ballpoint pen several times. Try to stretch the paper evenly so that it fits neatly around the plastic base. This will become the body of the future rocket.
3. Secure the edge of the paper with electrical tape so that it does not unfold in the future. Carefully cut off possible irregularities with clerical scissors.
4. Cut off a small piece of electrical tape and plug the rocket body with it on one side.
5. From the electrical tape, cut three pieces about 6-7 centimeters long. Fold each of them in half, but do not glue until the very end. Cut the edge at a 45 degree angle with scissors and attach to the tail of the rocket. These will be stabilizers.
6. Roll the remaining half of the paper into a cone shape and wrap it with electrical tape for strength.
7. Cut off a small piece from the nose of the rocket.
8. Fill the cone with adhesive solution ¾ and insert the clogged part of the rocket base into it. Hold the structure in such a position for some time so that the glue grabs and the parts become whole. Place the finished work on a flat surface or cardboard stand.

How to make a rocket from matches and foil - a master class

This easy and affordable tutorial explains how to make a match and foil rocket at home. The work requires the simplest materials, and the process itself takes just a few minutes. Then an impromptu aircraft can even be launched, however, it should be remembered that such events should be carried out only in the open air and, preferably, in the presence of adults.

Necessary materials for making a rocket from foil and matches

• kitchen matches - 1 box
• foil
• paper clip (or wire)
• needle (or safety pin)
• scissors

Step-by-step instructions for a master class on creating a rocket from matches with your own hands

1. Lay out a sheet of foil on the table, cut out a small fragment of 5x10 centimeters from it and cut it out with scissors.
2. Place an ordinary match and a needle together so that the sharp tip of the needle is adjacent to the place where the match is covered with sulfur.
3. Then wrap the structure with a pre-prepared piece of foil from the edge where the sulfur is located. Act very carefully and carefully. Make sure that the head with sulfur is completely covered with foil and that air does not penetrate inside.
4. After all these operations, very carefully pull out the needle, being careful not to damage the integrity of the foil layer. As a result, a small hole is formed through which the gas created at the time of combustion can escape, and the rocket can be launched into flight.
5. For a stand at a strong and strong paper clip, bend the core to the side.
6. Fix the rocket on the stand and leave it in that position. If the work is purely souvenir in nature, it can be placed in a cupboard under glass or placed on a table (or on any other flat and reliable surface). When the plans include a launch, it should be remembered that it can only be carried out on the street in compliance with elementary safety rules.
7. To send it into flight, it is enough to place the rocket launcher on a flat surface, light another match and bring the fire to where the foil covers the sulfur.
