The leading edge of the jet engine nacelle is provided with structure to prevent the formation of ice particles at the inlet of the jet engine. The nacelle is split into leading and trailing chambers and there is a partition separating the chambers, the leading one of which includes the anti-icing a ...

Jihad I Remlaoui: Cascade type aircraft engine thrust reverser with hidden link actuator. Rohr, Patrick J Schlesinger, Frank D Gilliam, July 20, 1993: US05228641 (57 worldwide citation)

A thrust reverser for use with fan jet type aircraft gas turbine engines. A ring around the aft edge of the nacelle is translatable aft to uncover a series of cascade sets, each of which includes a plurality of turning vanes that direct air passing through the cascades in a reverse direction. The ac ...

Gerald E Stephens: Method of making an acoustic panel with a triaxial open-weave face sheet. Rohr, Patrick J Schlesinger, Frank D Gilliam, June 9, 1987: US04671841 (56 worldwide citation)

A method of producing an open, triaxial woven, acoustic face sheet useful in acoustic energy absorbing panels for aircraft engines or the like.
