本文论述了在来流M1.72条件下,一个可变中心锥外压式进气道,强度为5～11％的六种滑流层在各种位置上进入唇口时对进气道稳定性的影响。 试验证明,强度低于10％的滑流层在唇口附近进入该轴对称进气道,并没有引起进气外罩内侧的附面层分离 强度直至11％的滑流层可以在进口处任意位置上进入该进气道,而不产生喘振。文献表明,强度仅为6～7％的滑流层就可以导致二元进气道的喘振,从而显示了轮对称进气道对滑流层进入所引起的喘振有较强的抵抗能力。
In this paper, we discuss the stability of the inlet duct when entering the lip at various positions under the condition of M1.72, a variable center cone external pressure inlet with intensity of 5 ~ 11% Sexual effects. It has been experimentally demonstrated that a slipstream below 10% enters the axisymmetric inlet near the lip and does not cause detachment strength on the inside of the intake shroud until 11% of the slipstream can be anywhere in the inlet Into the air intake, without generating surge. The literature shows that slipstreams with a strength of only 6-7% can lead to the surge of the binary inlet, which shows that the wheel-symmetrical inlet is more resistant to surging caused by the slipstream entering .
