Fighters are generally jets. Today's warplanes are powered by jet engines, which spray hot, high air into the rear to provide forward momentum. The jet engine has high thrust, high efficiency and low noise. Therefore, today's fighters generally use jet engines.
The injection engine is formed by burning fuel, and the high-heat and high-pressure gas ejected from the nozzle will bring forward power to the aircraft according to Newton's three theorems. This propulsion allows the aircraft to accelerate, climb, and operate flexibly, which is what the fighter must have the ability to quickly adjust its course and accelerate in mid-air in order to complete various tasks such as interception and attack.
In order to meet the requirements of aircraft in high speed and high maneuverability, the jet engine of the aircraft generally has high stability and large thrust. In addition, the engine of the new fighter also adopts a new type of propulsion vector control technology, which can achieve complex maneuvers such as rapid climbing, rapid landing and fast turning.
The design of the fighter also contains many high-tech elements, such as: flight control system, radar detection system, ** system, electronic warfare equipment and so on.
In addition to generating thrust, the jet engines of modern fighters have important features that allow the aircraft to operate effectively in different flight conditions. A few of the main features of jet engines for contemporary warplanes are listed below:
1.High thrust-to-weight ratio: Fighter engines require a higher thrust-to-weight ratio, that is, the engine can provide a large thrust-to-weight ratio, that is, the engine can provide a large thrust. In this way, the aircraft can quickly climb while maintaining good maneuverability.
2.High altitude and high thermal characteristics: Fighters tend to be at extremely high altitudes and high temperatures, which puts higher demands on their engines. This requires the engine to be able to provide sufficient power in extremely thin atmospheres (high altitudes) and at extremely high temperatures.
3.Down to supersonic speeds: Contemporary warplanes require a wide range of flight speeds, from low rpm to descent to supersonic speeds. The engine must have the ability to continuously propel at a wide range of speeds.
4.Reliability: Fighter engines must operate in harsh environments for long periods of time without incident. In other words, in order to ensure its reliability in actual combat, it must be rigorously tested and verified.
5.Repairable: The engines of the fighter aircraft should be designed in such a way that they can be easily repaired and repaired, so that if there is a problem or damage, they can be quickly returned to the aircraft.
6.Fuel Utilization: Although fuel utilization is not a major consideration, effective fuel consumption is still critical, which will have a direct impact on the range and endurance of the aircraft.
7.Modular construction: Many fighters now have modular engines, which means that their parts can be replaced individually, which shortens maintenance intervals and reduces costs.
8.**Performance: Modern fighter engines can be specially designed to reduce radar visibility in order to reduce radar cross-sections.
The jet engine is the culmination of space engineering, combining high performance, reliability and cutting-edge technology to make the fighter an indispensable player in modern warfare. As technology continues to evolve, future fighter engines will become more efficient, more stealthy, and smarter. Light firearms.
