Abstract
An improvement in an air intake for an aircraft engine, particularly a prop-jet engine, which intake is ring-shaped at the forward part thereof and has a central, non-rotatable body mounted in said intake, which together form an intake diffuser, the improvement comprising a displaceable inlet lip on said intake, said lip being displaceable to sealing contact against said central body and against the direction of air onflow, and said lip in said sealing contact position forming a ring-shaped inlet gap behind said lip.
Claims5
In an air intake for an aircraft engine, particularly a prop-jet engine, which intake is annular at the forward part thereof and has a central, non-rotatable body with a convex surface mounted in said intake,
- the improvement which comprises displaceable annular inlet lip means, having a concave inner surface, on said intake,
- said lip means being diplaceable to sealing contact against said central body and against the direction of air onflow, whereby a first air inflow channel is closed to air and a second air inflow channel behind said lip means is opened to air, said latter channel having an opening pointing away from the direction of air onflow.
