- metal pipe welder.
Prepare a segment of metal pipe with a diameter of 250 millimeters and a length of 360 millimeters.On both sides welded thereto conical cap with hole in the middle.The hole in the lid of a diameter of 80 millimeters and 50 millimeters in the second.This is a combustion chamber.
Next one side of the combustion chamber hole 80 mm welded piece of pipe of suitable diameter and length of 400 millimeters - a nozzle.After the required U-shaped bent tube, an inner diameter of 50 millimeters.One side of the U-shaped pipe length of 510 millimeters, the second side - 250 mm and connecting the sides of a central po
rtion of the tube is 400 millimeters.
long end of the U-shaped pipe is welded 50 mm hole in the combustion chamber, and to the short end must be welded socket narrow end.Dimensions socket: length 1030 mm, the narrow end 50 millimeters, 150 millimeters wide.The engine will have a U-shape.After the explosion of fuel and air mixture in the combustion chamber creates a vacuum region, which immediately enters a new portion of air and fuel.
engine can run on many fuels, but easier to use propane.Weld metal tube for supplying gas into the combustion chamber.To ignite the mixture, use automotive spark, which is produced through a bobbin supply AC voltage.
Tip 2: How to make a jet engine
jet engine - it's quite a complex device.For the first time on such a type of airplane engines took to the skies only in 1939.It was the German "Heinkel 178".Currently, these types of motors are used everywhere.But their structure becomes more complicated every year.
jet engine very easy on the principle of its work.It is necessary that the air just got into the engine, which would be mixed with the fuel (usually used for this purpose kerosene), and then all this would spark ignites.Thus, a jet stream, which drives the missiles and aircraft.
to create a jet engine in the first place needs housing.The housing contains all the basic units of the engine.This fan, which supplies air to the engine , and cools it during operation.After the fan is a compressor that pressurizes to a compressed air is introduced in the combustion chamber.The combustion chamber has the air is mixed with fuel, and then going through a directed explosion spark to get the jet stream.In some ways this structure resembles the carburetor car.Then the jet stream from the combustor is routed to a turbine jet engine.A turbine made of several hundred small "blades" and a shaft to which are attached the fan and compressor.When the jet stream goes to the turbine, the whole system is set in motion.Thus, for jet engine only needed a constant supply of fuel.
last detail design of this type of engine is the nozzle.The nozzle is already creating the jet stream, which results in the movement of the aircraft.It is composed of the heated mixture has fallen from the combustion chamber through the turbine nozzle, and the cold air supplied by the fan, which is passed through to the internal compartments of the engine for cooling.
Jet engines are divided into several categories.There is a classic, turboprop and turbofan jet engines.
Be careful of any jet engine explosive.
when the engine is very hot, even to melt, so long it is impossible to work.But if you build a slatted enclosure around the hot parts of the engine and fill the space between the casing and the motor housing a low-melting metal (copper), the engine itself will not begin to melt until the buffer metal evaporates.Although this will increase the weight of the apparatus and the complexity of manufacturing.
