What is the power of the engine of the plane?

So, for common helicopters, most of the power is concentrated at 400-1000KW. The engine power of helicopters is directly calculated in kilowatts, which is the same as that of an electric motor. Unlike turbine or turbofan engines, it is calculated by thrust. So this unit does not need to be converted.

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 willThe originally configured 500-kilowatt piston engine has been replaced with a power of 735-kilowatt piston engine with a power of 735 kilowatts.

Helicopters are different, and the power varies greatly, from a few hundred kilowatts to 8,000 kilowatts. The helicopter uses a turboshaft engine, and the output power is calirated in kilowatts, which is the same as the power standard of the motor. 1000 kilowatts is 1000 kilowatts.

How much horsepower is the helicopter engine

1. The bull thrust can be roughly converted to 1 kilowatt of power, so the thrust of this engine is 256000/15=17067 kilowatts, and 1 kilowatt is about 36 horsepower. Therefore, 17067*36=23210 horsepower, and aviation kerosene is used to propult.

2. Engine: Su-6-1, Su-6-2 - 1 M-71 piston propeller engine, rated power 2000 horsepower. Su-6-3 - 1 M-71F piston propeller engine with a rated power of 2200 horsepower.

3. The most powerful engine used in general cars is a 12-cylinder 220-horsepower engine, while the largest piston engine used in airplanes has 28 cylinders, which 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.

4. The horsepower of the plane is 500 horsepower per ton. The definition of horsepower is: 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.

How much horsepower does a small aircraft engine have

1. If you insist on having a two-seat, then Let me tell you, 30 horsepower is enough. Shijiazhuang Aircraft Factory once imitated an American aircraft with two seats side by side, called Dragonfly, using a Cayunna 430 engine with a power of 30 horsepower.

2. The triangular-wing aircraft like Bee No. 5 seems to have 22 horsepower. Aviation knowledge has been introduced. Methanol engines are used in most fuel model engines. Fixed wing: Most of the engines are 40-210, which are divided into 2-stroke and 4-stroke. The 2-stroke power is greater than 4-stroke power, which is equivalent to 4-stroke 110-level power.

3. Some single-person micro-power triangle wings have 15 horsepower, and single-person fixed wings have 30-50 horsepower, such as "Afu", "Mini MAX" and crickets. The two-person ones are more than 80 horsepower, and the general one is about 120 horsepower.

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. WaveThe cruising altitude of the sound 747 and Boeing 747 is 13,700 meters, the maximum fuel capacity is 134 tons, the commercial load is 90 tons, the maximum Mach number is 0.88, and the range is 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.

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.

How much horsepower does a self-made aircraft need

If the optimization is done well, it is generally 300 horsepower/ton. That is, 1 horsepower can raise 3kg. An ordinary motorcycle is fine. But the engine speed needs to be adjusted.

According to the technical parameters of small helicopters abroad for your reference, the take-off weight of the whole aircraft is 650 kg, and the engine is 4 cylinders with 124 horsepower.

In addition, it is recommended that you learn to fly first. After having a certain understanding of airplanes, you can start to build airplanes. If you insist on having a two-seater, I'll tell you, 30 horsepower is enough. Shijiazhuang Aircraft Factory once imitated an American aircraft with two seats side by side, called Dragonfly, using a Cayunna 430 engine with a power of 30 horsepower.

First of all, you need to determine your whole plane plus your weight, and secondly, determine the speed of the propeller and the distance. Then you can calculate the approximate power you want. I think it's more than 1,500.
