Eaton Char-Lynn Motor – Aero Motor: Which Types
The Eaton Char-lynn Motor illustrates the characteristics of three types of aero motors:
1 piston aero motor. An early aerospace motor used in aircraft or helicopters to drive a propeller or rotor. The large piston aero motor has a power of 2,500 kW. Later it was replaced by a gas turbine motor with high power and high speed performance. However, low-power piston aircraft are still widely used in light aircraft, helicopters and ultralight aircraft.
2 gas turbine motor. The most widely used. These include turbojet motors, turbofan motors, turboprop motors, and turboshaft motors, all with compressors, combustion chambers, and gas turbines. Turboprop motors are mainly used for aircraft with a speed of less than 800 km; turboshaft motors are mainly used as helicopters; turbofan motors are mainly used for higher speed aircraft; turbojet motors are mainly used for supersonic aircraft.
3 ramjet motor. It is characterized by no compressor and gas turbine, and the air entering the combustion chamber is pressurized by the punching action at high speed. It is simple in construction and large in thrust, and is especially suitable for high-speed and high-altitude flights. Due to the inability to start on their own and the poor performance at low speeds, the scope of application is limited and is only used on missiles and targets launched in the air.
The above-mentioned motors are all taken from the atmosphere as air oxidants for burning fuel, so they are also called air intake motors. Others include rocket motors, pulse motors and aerospace motors. Rocket motors consume too much fuel and are not suitable for long-term work, only for short-term aircraft acceleration (such as starting accelerators). Pulse motors are mainly used in low speed drones and aerospace model aircraft. Aero-motors powered by solar cells are only used in light aircraft and are still in the experimental phase.
