英文释义
名词 n.
-
A stall (“sudden loss of lift”) caused when the airflow over an aircraft's wings is disturbed by shock waves that occurs at a specific Mach number when the aircraft is accelerating to transonic speeds.
— When I was down to 32,000 feet the altimeter was spinning merrily and the dive was very steep and I was pulling back on the stick in the usual way due to the change of trim at the shock stall.
动词 v.
-
Of an aircraft or a component of it: to undergo a shock stall.
— The tailplane usually becomes more effective as a stabiliser at high Mach numbers because there are decreases of wing lift-curve slope and rate of change of downwash with mean lift coefficient. The latter effect is mainly due to the wing-root shock stalling at a lower Mach number than the rest of the wing.
