A rocket is not just a toy. This is a real aircraft that works on the same principle as a real rocket. The launch of such a rocket could be a worthy end to the holiday.
Instructions
Step 1
Make a fuel mixture, mixing saltpeter, coal and sulfur in the required proportions. Make a mixture for the wick by mixing saltpeter and sulfur at the rate of 9 parts of saltpeter to 1 part of sulfur.
Step 2
Drill the metal part of the sleeve from the side of the capsule attachment. Remove the capsule fasteners.
Step 3
Drive a nail into the board. The nail should protrude 2 cm above the board. Gently grind off the protruding end of the nail, giving it smooth conical contours. Slightly blunt the sharp end.
Step 4
Remove metal filings thoroughly. Place the metal part of the sleeve on the nail and pour well-mixed fuel into it to ¾ of the height.
Using a wooden round stick, compress the fuel into the sleeve by lightly hitting it with a mallet.
Step 5
Cut a circle out of writing paper that is slightly larger than the inner diameter of the sleeve. It must completely cover the fuel layer. Pour the fuel mixture on top of the resulting partition with a layer of 0.5 cm and glue the sleeve on top with a layer of thin paper. This charge serves to release the parachute.
Step 6
Take a round stick with a larger diameter. Wrap it in a layer of newsprint. Secure it with glue and let dry. After that, lightly saturate the newspaper layer with oil and wipe off.
Step 7
Wind a 2-round thick drawing paper tube onto the resulting blank. Thoroughly coat each turn with glue. Dry the resulting tube on a stick.
Remove the tube from the stick. Remove the newsprint layer; you will no longer need it.
Step 8
Make a rocket fairing out of softwood. It is a cork 6-7 cm long, the upper end of which comes down to a cone and ends with a rounding, and the lower end, 1-1.5 cm long, is tightly inserted into the upper part of the paper tube. You have half-strengthened the rocket body and fairing.
Step 9
Make stabilizers out of whatman paper. There must be at least three of them. They are triangles and must have petals to connect to the rocket. Fasten the stabilizers to the rocket body with glue. From the end of the fairing, which is inserted into the rocket body, fix a metal ring or a bracket with an inner diameter of 0.5 cm, made of steel wire. Close the ring. It serves for attaching a parachute.
Step 10
Insert the engine sleeve into the bottom of the rocket. He must fit tightly and get back with the demand. If the engine does not hold well, glue an additional 3 cm wide paper ring from the inside of the housing. Dry the housing completely. Paint it brightly with waterproof paint.
Step 11
Make a parachute. The diameter of the canopy is 15-20 cm. For this model, use a band parachute. Attach one end of the tape to a wooden stick. Attach a loop of 10 cm long thread to the ends of the stick. Tie a 10 cm piece of aviation rubber to one end of the loop. Tie the end of the rubber thread around the wire ring put on the fairing. Additionally secure it with a regular thread. Tie another 10 cm long thread to the fairing ring. Also tie a piece of aviation rubber to it, and another 5 cm of regular thread to it. Attach this thread to the inside of the rocket body, three centimeters from the top end of the body tube. You can pass it through the entire body by making a hole in it and pasting it with a paper ring for strength.
Step 12
Lay down your parachute. To do this, wind the tape into a roll, starting from the free side. Press the roll from the outside with the stick to which the parachute is attached. Slide the resulting roll carefully into the rocket body. Lay the tape and thread of attachment to the fairing on top. Cover the structure with a fairing.
Step 13
Make a starter device. Cut a piece of iron wire 120 cm long. From whatman paper on the wire, glue 2 cylinders 1 cm long and a little larger than the diameter of the wire. The rings should slide freely on the wire. Fix the resulting rings on one longitudinal line on the rocket body with strong glue. Fix one ring at the junction of the body with the stabilizer, the other at the top, about 1 cm from the fairing. The rocket should slide freely along the wire. At a distance of 50 cm from one of the ends of the wire, wind a restraining ring of any wire around it. Dalge of this ring, the rocket should not descend. This side of the wire should stick into the ground.
Step 14
Make a fuse. You can take a ready-made fuse from a firecracker or firecracker, but the length may not be enough. Make a stop. Take cotton thread and fold it 6 times. You should get a piece with a length of 8 cm. Weld the paste. Dampen the thread with starch paste. Dip it along its entire length in a composition similar to that of fuel, but without charcoal. A layer of this composition should adhere to the thread. Dry the resulting cord.
Step 15
Insert the engine into the rocket before starting. Insert the wad into the rocket body before inserting it. The wad can be a piece of styrofoam. Bend the cord at one end and insert that end into the nozzle. The rocket is ready
