The F-15 looks very bulky. Why is the mobility still very high?

The front edge of the F-15's wing is relatively not so sharp, and there is no front edge flap, so the F-15 is not as mobile as the Su-27 at a large angle of attack.

The fundamental goal of the F-15 fighter design is to use it at high altitude. It has an extremely high maximum stall speed, which allows it to have excellent maneuver at extremely thin altitudes in the atmosphere.

The F-15 is the current main air control fighter of the U.S. Air Force, which can be used to seize air control in the war zone and attack ground targets. In 1965, as the successor model of the F-4, McDow's design was approved, and it was the F-15 single-seat twin-engine supersonic heavy jet fighter.

Engine model F15

1. There are two types of engines of F15, one is the F100 of Prathuitni, and the other is the F110 engine of General Electric.

2. The earliest F15 (including F15A/B, and early batches of C/D/J) is an inclusive F100-PW-100 with a thrust of 111kN. At that time, the engine couldIt was not good to rely on it and had all kinds of problems, so at that time, the F15 stopped flying frequently and was nicknamed the "Hanger Queen".

3. The derivative models of the F-15 are all here. F-15A: the single-seat air combat type of the F-15 fighter, equipped with the F-100-PW-100 engine. F-15B: the two-seat coach type of the F-15A, originally called TF-15A, and later renamed F-15B. .

4. Confirm the fault: the vehicle is towed into the factory, and the motor is running when the vehicle is started, but the car cannot be started. Check that the vehicle's fuel level is 1/4. After connecting to the computer for quick measurement, there is a fault code 249300: oil rail pressure monitoring when the engine starts, and the oil rail pressure when the vehicle starts is too small.

5. The plane with a propeller engine is not an F15.F15 is an F100-PW-100 turbofan engine. Aircraft with propeller engines include Viscount 843 aircraft and SHORT-360 aircraft.

What are the f15 engine failure cases

Vehicle information: Model F15 engine N57 driving distance 165218KM Fault phenomenon: the vehicle turns off while driving, and the vehicle cannot start. Repair process: Fault confirmation: When the vehicle trailer enters the factory to start the vehicle, the motor works, but cannot be put on the vehicle. Check that the vehicle's fuel level is 1/4. There will be a fault code 249300 immediately after connecting to the computer.

The fuel injector drips. The fuel injector drips, because the engine has just been turned off.The degree is still very high, and the leaking fuel will turn into oil vapor into the intake pipe. At this time, the hot start will cause the mixture to be too thick, making it difficult to start.

Spark plug failure: Spark plug failure will cause the car to jitter at idle speed, significantly reducing power and increasing fuel consumption. Solution: Go to the 4s store to check and repair the spark plugs in time. Carbon accumulation of fuel injector: Carbon accumulation of fuel injector will lead to insufficient power, idling jitter, difficulty in starting, and increased fuel consumption.

One is a device failure. This problem is generally the ignition coil, capacity electrical appliance, and electronic ignition module. That is, it can start at the beginning, turn off after a while, and then start again and turn off again. There is also an oil road failure. The gasoline pump is damaged, the oil pipe is broken, the oil inlet of the vaporizer is blocked, and the fuel tank is out of oil.

Air intake system problems: Engine jitter and fault light on may also be related to the air intake system.For example, air flow sensor failure, intake manifold leakage or intake valve failure may cause the engine to run abnormally. The solution is to check the parts of the air intake system and repair or replace any problematic parts.

Who knows what model of F15's engine is

Airplanes with propeller engines are not F15. F15 is an F100-PW-100 turbofan engine. Aircraft with propeller engines include Viscount 843 aircraft and SHORT-360 aircraft.

There are two types of engines for F15, one is Pratjutni's F100, and the other is General Electric's F110 engine.

The simplified model of F-15E ordered by Saudi Arabia. The engine is F100-PW-229, but the level of avoic equipment is lowered, and a large number of equipment on F-15C/D are used. Although the radar is APG-70, it has canceled the ground surveying and mapping capability, and its performance is comparable to that of APG-63. In addition, some electronic confrontation equipment has been canceled, reducing the performance of the Blue Shield pod.
