AXIAL DIRECTION DIVERGENCE SECTION SLOT NOZZLE, EJECTOR NOZZLE BRIDGE MEMBER, METHOD FOR ADJUSTING EXHAUST PLUME AND METHOD FOR INCREASING PROPULSION FORCE

摘要

PPROBLEM TO BE SOLVED: To provide an axial direction divergence section slot nozzle for an engine adjusting exhaust plume and propulsion force by using flow of surrounding air. PSOLUTION: This invented nozzle includes a plurality of divergence flaps 12 arranged with intervals, at least one device moving the divergence flap 12 to change nozzle section area in a throat zone, and a bridge member 20 arranged in a middle of adjoining flaps. The bridge member 20 includes a bridge bracket 216 and a seal element 204 connected to the bridge bracket. The seal element includes a top surface 226. The bridge bracket includes lower surfaces 222, 224 expanding to the upper surface 226 of the seal element. In a preferable form, the bridge bracket has a shape giving a variable slot dimension according to a nozzle throat jet zone. PCOPYRIGHT: (C)2006,JPO&NCIPI
