Engine types of fighters

Engines used by fighters can be divided into the following types: rn (1) Piston aircraft engine: early aviation launch applied on aircraft or helicopters Machine, use it to drive propellers or rotors.The power of large piston aircraft engines can reach 2500KW (3,400 horsepower).

The paddle fan engine is a strange engine. It is designed to open the outer duct of the turbofan engine so that the fan is directly exposed to the engine, which can have both the economy of a propeller aircraft and the large thrust of the turbofan engine.

The engines of fighter jets are mainly divided into piston, stamping, turbojet, turbine fans, turbine shafts, turboprops, etc. according to the working mode. The fuel of piston engines, like cars, is mainly gasoline. In the early days of the establishment of China's air force, due to the shortage of gasoline, there was even a situation of using alcohol as fuel for flight training.

Civil aviation aircraft and modern fighters generally use turbine fan engines.The helicopter uses a turboshaft engine. Civil aviation can generally use a high-thrust turbofan engine with a high culvert ratio without pursuing too high speed. The highest thrust and high flight speed of the fighter jet do not consider the economic performance of fuel, and use a turbofan engine with a large thrust-to-weight ratio.

Types of civil airliner engine

There are mainly the following types: Turbofan: This is the most common type of engine in civil airliner aircraft. The main difference between turbofan engines and turbojet engines is their combustion chamber structure. The advantages of this engine are high thrust, low fuel consumption and low noise, so it is widely used in modern civil airliners.

Nowadays, civil airliners generally use turbofan engines.In terms of its working principle, the turbofan engine belongs to a kind of turbine (the rotation of the fluid impact impeller generates power); at the same time, in terms of its working principle, the turbofan engine belongs to a kind of jet engine (ejecting high-speed fluid work).

Aviation engines are mainly divided into two categories: turbofan engines and turbojet engines. Turbofan engines are the most common and widely used type of engines in modern aviation.

What kind of engine is usually used for aircraft model aircraft? Motor or vortex spray?

1. Including turbojet engines, turbine fan engines, turboprop engines and turbine shaft engines, all have compressors, combustion chambers and gas turbines.

2. Aviation model. The most used turbocharged engine is the centrifugal turbocharged vortex injection engine, that is, the vortex injection engine. This is also relatively expensive. Generally, it is imported from Germany for tens of thousands, and the service life is about 20 hours. The turbine engine is a special kind of reciprocating engine. You may be mistaken here..

3. Fighter modelIt belongs to the real machine series in the aircraft model. Generally, the most used power of the real machine is the channel power group (electric, channel + impeller + motor) and the micro turbine jet (fuel) engine. The electric channel has a wide range of applications, and most of them are like real machine configurations. But the efficiency is lower than that of the propeller, so it consumes more electricity.

4. Depending on what kind of aircraft model you want, the 3D KT performance machine can complete the production of the aircraft for a few dozen yuan. A set of electronic equipment is estimated to cost more than 600 yuan.
