SUPERSONIC AXIAL VELOCITY COMPRESSOR STUDY. VOLUME IV. TWO-DIMENSIONAL CASCADE TEST RESULTS.
Abstract
This volume presents a description of the cascade tests conducted to establish feasibility of the supersonic axial velocity compressor concept. Two series of tests were conducted at a free stream Mach number of 2.7 using a cascade of four two-dimensional impulse blades, having about 60 deg. turning. The blade profile was modified slightly for the second test series to alleviate suction surface boundary layer separation. The angle of attack of the cascade was varied roughly plus or minus 15 deg. Measurements consisted of pressure distributions along the blade surfaces and the total pressure recovery at the passage exit. The maximum mass-weighted recovery was 80%. (Author)
