Plain inlets and inlets with scoop-type doors were tested in wind tunnel using Ames Lift Engine Pod containing five YJ85 engines to determine inlet/door performance characteristics during lift-engine operation and to establish engine start and acceleration characteristics during transition; overall inlet pressure distortion levels were lower than nominal acceptable level of 10%; acceptable inlet total pressure recoveries were achieved, and improvement in engine windmilling characteristics was observed with inlet doors; feasibility of windmill starting of lift engines having inlet doors at landing transition speeds between 200 and 240 knots was shown.
