critical mach number उदाहरण वाक्य

In aircraft not designed to fly at or above the critical Mach number, the shock waves that form in the airflow over the wing and tailplane are sufficient to stall the wing, render the control surfaces ineffective, or lead to loss of control of the aircraft ( such as Mach tuck, when shock waves in the airflow over the elevator send the aircraft into an uncontrollable dive ).
