Information × Registration Number 0211U007320, 0110U004475 , R & D reports Title Developing an estimation criterion of stall modes in view of profile and face boundary layers and check of its working capacity by results of tests of low pressure compressor (LPC) of gas-turbine engine GTE DN80. popup.stage_title Head Koval Yacheslav, Registration Date 15-04-2011 Organization A.Podgorny Institute for Mechanical Engineering Problems of the National Academy of Sciences of Ukraine popup.description2 On the basis of the analysis of experimental and settlement-theoretical researches of features of formation of profile and face boundary layers in axial compressor steps it is analytically received criterion ratio for definition of border of failure. The theoretical basis new criterion ratio - a variation problem about stability of the current ad equating to a maximum of a stream of mechanical energy, which decision is carried out by means of A.M.Lyapunov's second method. With the purpose of introduction of a new method of calculation of border of steady modes in practice of designing of axial compressors at the full-size stand of enterprise Gas Turbine Research and Production Complex "Zorya-Mashproekt" U340 are carried out natural skilled researches of the compressor of low pressure ГТД ДН80 in a wide range of modes on frequency of rotation and the charge of air. As a result of experimental researches necessary data to calculate the axial velocity of failure.
