Pitot intakes - aircraft maintenance , Other Engineering

Pitot intakes:

This intake is suitable for subsonic or low supersonic speeds. Examples, 707, 747, A300B, Tristar, etc. The intake is usually short and is very efficient because the duct inlet is located directly ahead of the engine compressor. As the duct length increases, the risk of small airflow disturbances and pressure drop is increased. This inlet makes maximum use of ram effect until sonic speed is approached when efficiency falls due to shock wave formation at the intake lip. Pitot inlets can however suffer from inlet turbulences at high angles of attack and/or at low speeds.

The pitot type intake can be used for engines that are mounted in pods or in the wings although the latter sometimes requires a departure from the circular cross section due to the wing thickness
