Influence of air injection into the intake support struts of a turboshaft engine
Авіаційно-космічна техніка та технологія, 2022 The aerodynamic wakes behind the struts cause uneven flow at the compressor inlet. An irregularity at the compressor inlet of a turboshaft engine causes unstable operation of the compressor, which can deteriorate the engine economy and a decrease its ...
