How to make a USB powered mini jet engine and lighter

How to make a USB powered mini jet engine and lighter

Jet thrust is the most powerful that exists so far. You can clearly demonstrate its principle of operation on a homemade model. This is a completely safe device, as it runs on gas for refueling 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;
  • board;
  • thin hose
  • gas lighters – 2 pcs.

Jet engine manufacturing process

To make the engine body, 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 the axle with blades.

4 discs are cut from thin sheet metal for the inner diameter of the pipe. They need to be drilled in the center, cut the blades on them and bend the impellers out of them.

Next, take a piece of a bicycle spoke 70 mm long. Impellers are put on it. To secure them, glue and sleeves are used from an empty ballpoint pen cut into pieces.

The axle with blades is inserted into the tube. Then the second mount is glued into it. To prevent the axle from dangling, you need to put bushings from the rod in front of the brackets.

A cone with a cut off top is bent from thin sheet metal. 3 holes are made in it.

Metal tubes are glued into 2 holes on the cone.

They can be removed from the telescopic antenna; metal rods from a ballpoint pen will also work.
The motor is screwed to the wood base with sheet metal brackets with the hole in the cone without tube at the top. Similarly, an electric motor is attached to the sole. Its axis is connected to the jet motor by means of a rod from the handle.

Thin hoses are pulled over the tubes from the cone.

They must 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 enter the cone of the jet engine, where it needs to be ignited. Then, when starting the air blowing, draft will appear. It will continue until you release the lighters.
