Cloud-Droplet Ingestion in Engine Inlets with Inlet Velocity Ratios of 1.0 and 0.7
Abstract
The paths of cloud droplets into two engine inlets have been calculated for a wide range of meteorological and flight conditions. The amount of water in droplet form ingested by the inlets and the amount and distribution of water impinging on the inlet walls are obtained from these droplet-trajectory calculations. In both types of inlet, a prolate ellipsoid of revolution (10-percent thick) represents either part or all of the forebody at the center of an annular inlet to an engine. The configurations can also represent a fuselage of all airplane with side ram-scoop inlets. The studies were made at an angle of attack of 0 deg. The principal difference between the two inlets studied is that the inlet air velocity of one is 0.7 that of the other. The studies of the two velocity ratios lead to some important general concepts on water ingestion in inlets.
