Jet propulsion powerplants

摘要

A flow diverter arrangement for an aircraft comprises a first duct 17 for receiving propulsion fluid from the powerplant 11 and delivering it to a first location 18, a second duct 19 merging with the first duct 17 at a communication aperture 23 and adapted to deliver propulsion fluid to a second location, a flap member 24 pivotted for movement between a first position in which it closes the communication aperture 23 and a second position in which it closes the first duct, and a diverter device 31 for diverting propulsion fluid into the second duct when the flap member is in its second position.
