초록

A separating inlet duct (14) is provided with a reduced arm, bypass throat section (46) to restrict the bypass flow (18b) during periods of high speed aircraft flight. An ejector (34) ensures a minimum bypass flow (18b) during hover or low speed flight. An icing resistance baffle (40) having a rounded leading edge (42) defines the sized throat section (46).
