Jet thrust is the most powerful of all that still exists. You can clearly demonstrate its principle of operation on a homemade model. This is a completely safe device, as it runs on gas for refilling lighters, so it can be assembled at home.
Materials:
- pipe 32 mm;
- tin or thin sheet aluminum;
- Super glue;
- bicycle spoke;
- electric motor from a toy;
- empty ballpoint pen refill;
- board;
- thin hose
- gas lighters – 2 pcs.
Jet engine manufacturing process
To make the motor housing, you need to cut a piece of pipe 55 mm long.
A sheet metal bracket is glued into one end of it. It should have a hole in the center for an axis with blades.
4 disks are cut from thin sheet metal to fit the inner diameter of the pipe. They need to be drilled in the center, blades cut into them and impellers bent from them.
Next, take a piece of a bicycle spoke 70 mm long. Impellers are put on it. To secure them, glue and bushings from an empty ballpoint pen refill cut into pieces are used.
The axis with the blades is inserted into the tube. Then the second fastener is glued into it. To prevent the axle from dangling, you need to place bushings from the rod in front of the brackets.
A cone with a cut off top is bent from thin sheet metal. It has 3 holes.
The cone is glued to the engine housing.
Metal tubes are glued into 2 holes on the cone.
They can be removed from the telescopic antenna; metal rods from a ballpoint pen are also suitable.
The motor is screwed to the wooden base with sheet metal brackets so that the hole in the cone without the tube is at the top. Similarly, an electric motor is attached to the sole. Its axis is connected to the jet motor via a rod from the handle.
Wires are soldered to the contacts of the electric motor.
Thin hoses are pulled onto the tubes from the cone.
They need to be continued to the free part of the wooden sole and connected to the fittings of the fixed lighters.
Now, when you press the buttons on the lighters, the gas from them will flow into the cone of the jet engine, where it needs to be set on fire. Then, when the air supply starts, draft will appear. It will continue until you release the lighter.
