What is the ignition of the model micro turbojet engine, how to make it last, how to control the throttle and what oil to use, heroes, please help.

Why don't you go to the 5imx forum, where there is a "hydrodynamic fixed wing" area with this thing.

As far as I know, there are electric starting (the motor drives the compressor impeller to rotate to a predetermined pressure, so that the oil and gas are fully mixed with the spark plug on the combustion chamber wall for ignition) and gas starting (manually injecting gas and igniting with the spark plug). Of course, electric start is more convenient, and it is generally "one-button start".

The service life of turbojet engine mainly depends on high temperature bearings. This bearing can't be made of stainless steel, it should be made of ceramics, which is resistant to high temperature. Generally, the service life is only 25 hours, but under normal circumstances, the engine is not broken, and the plane breaks down first when it falls.

Use an oil pump to control the throttle. When the throttle is large, the amount of oil pumped is large. The oil pump is connected to ECU (microcomputer for controlling the engine, a set on Taobao (here, a set refers to all turbojet parts except the engine), which is about 4500 yuan. If you don't want to spend money, you can also connect the oil pump directly to the oil receiver, but generally no one does this, which will lead to unstable combustion and increase the chance of parking in the air.

The oil is preferably aviation kerosene, but international 0# diesel can also be used if the design is reasonable. When the oil is mixed with 5% Mobil consumable aviation lubricating oil, it will be atomized and sprayed on the bearing during combustion, and of course it will burn itself (because it is too difficult to seal and lubricate the bearing, the life of the bearing without lubricating oil will be reduced from 25 hours to 10 second).

Finally, I don't have drawings, so I can buy them on Taobao (Taobao has drawings and finished products, as well as the ECU electronic control unit mentioned above). If you don't understand, you can download "Ali Want Want" and communicate directly with the shops on Taobao).
