How much horsepower does the plane have

1. The Mach number produced by different models is different, generally at 0.Between 86 and 0.88 Mach. The cruising altitude of the Boeing 747 and Boeing 747 is 13,700 meters, with a maximum oil load capacity of 134 tons, a commercial load of 90 tons, a maximum Mach number of 0.88, and a range of 13,000 kilometers. International airlines operate widely on transoceanic routes.

2. The power is 20,000 horsepower, 17,000 kilowatts, and the whole plane is 40,000 horsepower, 35,000 kilowatts.

3. kW. The engine horsepower of a small aircraft is 2500kW. In World War II, the piston engine was technologically innovated to optimize the performance and operating efficiency of the engine, from less than 10kW to about 2500kW.

What is the horsepower of an ordinary civil airliner, that is, kilowatts?

The engine power of the plane is about 2500kW. In World War II, the piston engine was technologically innovated to optimize the performance and operating efficiency of the engine, from less than 10kW to about 2500kW, and the fuel consumption was reduced from 0.5kg/(kW·h) to about 0.25kg/(kW·h).

Ordinary civil aircraft has 500 horsepower per ton, which is about the same as the thrust-to-weight ratio of Farari enso. Fighters have 1,500 to 2,500 horsepower per ton, which is larger than F1. Definition of horsepower: 1 horsepower = 735N/M, which is approximately equal to 75 kg/m/s, that is, 1 horsepower can increase the weight of 75 kg by 1 meter in 1 second.

The Mach number produced by different models is different, generally between 0.86 and 0.88 Mach. The cruising altitude of the Boeing 747 and Boeing 747 is 13,700 meters, with a maximum oil load capacity of 134 tons, a commercial load of 90 tons, a maximum Mach number of 0.88, and a range of 13,000 kilometers. International airlines operate widely on transoceanic routes.

One horsepower is equal to 0.735 kilowatts.1 horsepower (metric) = 1 horsepower (HP) = 0.735kW (kW) = 735W. Horsepower is the power of the vehicle, which is used to refer to the speed of the engine's work. The higher the power, the faster the engine's work.

How much power is the aircraft's engine

The maximum power that an aircraft jet engine can produce is 110,000kW. According to the relevant public information of the query, the engine power of the jet aircraft is about 110,000 kilowatts, which means that the engine does 110,000,000 joles of work per second, that is, the chemical energy of 110,000,000 joules per second is converted into the kinetic energy and potential energy of the aircraft.

The power is 20,000 horsepower and 17,000 kilowatts, and the whole plane is 40,000 horsepower and 35,000 kilowatts.

The largest piston engine used on the plane has 28 cylinders, and the power can reach 4,000 horsepower! If the power still does not meet the usage requirements, more than one engine can be installed on the plane.

Small propeller aircraft, the engine power is generally about 500 kilowatts. For example, the improved Yun-5B aircraft replaced the original 500-kilowatt piston engine with a power of 735-kilowatt piston engine with a power of 735 kilowatts.

The long-term power of human beings is only 0.4 horsepower, and the maximum take-off weight of the human aircraft does not exceed 100 kilograms (including people), so the flight speed is only a few meters per second. If the human aircraft is equipped with a 10CC model engine of only 1 horsepower, it is enough to take off and fly smoothly.

And the power of military armed helicopters is about 1000KW.The power of the domestic Wuzhishi is 1000KW. And large transport helicopters are more powerful. Therefore, for common helicopters, most of the power is concentrated in 400-1000KW.
