Abstract:

A turboprop engine has in flow series arrangement a crescent shaped inlet, an annular plenum, a compressor, a combustor, and a turbine. The plenum is defined by inner and outer annular walls. A support member referred to as a "boat tail" extends between the walls and is circumferentially positioned 180 degrees from the inlet. A strake extends downstream from the support member and is angled in a direction opposite the rotational direction of the compressor. Thus air entering the engine with either positive or negative swirl is forced to enter the impeller with negative swirl.

Abstract:

A seal compression tool is disposed at a readily accessible location externally of the cylindrical casing of a gas turbine engine, and has a camming surface thereon effective to interengage and axially shift the turbine nozzle of the gas turbine engine. Such axial shifting uniformly and controllably compresses a static seal carried between the turbine nozzle and the casing at a remote, relatively inaccessible location inside the gas turbine engine.
