Turboprop with impeller inlet strake |
摘要 |
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.
