The aircraft’s engine power is around 2500kW.
During the Second World War, the piston engine underwent technological innovation, which optimized the performance and operating efficiency of the engine. It increased from less than 10kW to about 2500kW, and the fuel consumption increased from 0.5kg/( kW·h) is reduced to about 0.25kg/(kW·h). At the same time, the running time after the rectification increased from a dozen hours in the traditional sense to 2000-3000 hours. By the end of World War II, piston engine technology had become very sophisticated.
In the 21st century, the development of aviation engines is further accelerating, which will bring new major changes to the field of human aviation. At present, traditional aero engines are developing towards gear transmission engines, variable cycle engines, multi-electric engines, intercooled recuperation engines and open rotor engines. Non-traditional pulse detonation engines, scramjet engines, turbine-based combined engines, And solar power and fuel cell power are also continuing to mature.

Relevant power defined on aircraft engines:
Maximum continuous power: It is the engine that can work continuously, that is, there is no working time limit. The maximum power generated. However, in order to extend the life of the engine on the wing, this power is not used under normal circumstances and is only used under special circumstances. For example, when a twin-engine aircraft is flying with one engine, the maximum continuous power can be used to meet thrust requirements.
Maximum cruise power: the maximum thrust allowed during normal cruise flight.
Maximum climb power: the maximum power allowed during climb.
Idle power: the lowest power required to keep the engine working stably. The idle speed of the engine is affected by the atmospheric temperature. When the atmospheric temperature drops, the idle speed decreases; when the atmospheric temperature rises, the idle speed also increases. When determining the idle power, many factors must be considered, such as the minimum rotor speed limit, minimum bleed air pressure limit, minimum fuel flow limit, generator speed limit, compressor airflow stability, aircraft taxiing thrust, acceleration time, etc.
In addition, some engines also provide for low idle (or ground idle) and high idle (or approach idle). Low idle is used for certain engine conditions on the ground and in the air. When the aircraft is landing and approaching, use high idle to shorten the time required for the engine to accelerate to maximum power when the aircraft goes around. After the plane lands for a certain period of time, it will switch from high-idle to low-idle.
