Abstract

877,976. Controlling boundary layer flow. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. March 31, 1960 [March 11, 1959], No. 8368 /59. Class 4. [Also in Group XXVI] To reduce the tendency of an axial-flow compressor (see Group XXVI) to surge, due to boundary layer effects, an auxiliary centrifugal compressor 21 is arranged between two stages 5a, 5b of the axial-flow compressor to draw in air at 25 from the inner wall of the compressor flow path, compress it and discharge it downstream from 26, at increased velocity, over the said inner wall.
