摘要

gas-turbine engines. SUBSTANCE: air intake is provided with leading and antistall unit. Leading edge of air intake is provided with wave-like recesses over inner surface which widen with distance between leading edge and profiled projections on tip of leading edge. Amount of recesses first increases smoothly and after obtaining maximum magnitude it smoothly and after obtaining maximum magnitude it smoothly decreases to zero. EFFECT: enhanced efficiency during entire service life due to absence of members requiring adjustment of flow sections and their closing. 2 cl, 3 dwg
