Experimental study of the critical speed response, of a

The frequency of the effective critical speed may be shifted by up to 20%. Furthermore, a beating frequency was observed in the amplitude data after the rotor had passed through the critical speed. This phenomenon is shown to be the vector sum of a synchronous component of amplitude and a nonsynchronous transient component (at the critical speed).

Predicting your race time with the critical velocity speed

The actual regression equation was MT (marathon time) = 445.3 (50.3 X CV), where CV is critical velocity. In other words, if your critical velocity happened to be 5 metres per second, your predicted marathon clocking would be 445.3 minus (50.3 X 5), or 193.8 minutes. Of course, the higher the critical velocity, the faster the marathon time.

Longitudinal stability of airships How is the critical

The critical speed is higher the blunter the airship is. The slender Zeppelins of the first World War had a fairly low critical speed (maybe 8 m/s), but the Cargolifter's critical speed was around 20 m/s. During the design phase the required power had to be increased by 40% to raise the cruise speed by a sufficient margin above the critical speed.
