critical mach number उदाहरण वाक्य
उदाहरण वाक्य
- The speed was equivalent to a Mach number of 0.62 while the loading condition caused Petter to select a thick wing section which would later be demonstrated to have a critical Mach number of 0.6.
- In general, a thicker wing will have a lower critical Mach number, because a thicker wing deflects the airflow passing around it more than a thinner wing does, and thus accelerates the airflow to a faster speed.
- For instance, the fairly-thick wing on the P-38 Lightning has a critical Mach number of about . 69 . The aircraft could occasionally reach this speed in dives, leading to a number of crashes.
- When the airplane exceeds its critical Mach number ( such as during stall prevention or recovery ), then drag increases or Mach tuck occurs, which can cause the aircraft to upset, lose control, and lose altitude.
- The aircraft was still subsonic, but the critical Mach number was increased from 0.79 to 0.86 at sea level and to 0.895 at 35, 000 ft ( 10, 000 m ), improving performance markedly over the Panther.
- In aerodynamics, the "'critical Mach number ( Mcr or M * ) "'of an aircraft is the lowest Mach number at which the airflow over some point of the aircraft reaches the speed of sound, but does not exceed it.
- Somewhat surprisingly, the new trapezoid wing had lower critical Mach number than the old elliptic one, bringing one of the test pilots who flew the " jet Spiteful " ( the Supermarine Attacker ) to remark that the original wing should have been retained on the jet.
- Improvements were made to the wing shape, incorporating a dog-tooth leading edge, for the effect of raising the critical Mach number of the aircraft . From 1963 onwards, all frontline J 29Fs were equipped with AIM-9 Sidewinder infrared-seeking air-to-air missiles.
- In late 1951, the lab hosted a talk by Adolf Busemann, a famous German aerodynamicist who had moved to Langley after World War II . He talked about the behavior of airflow around an airplane as its speed approached the critical Mach number, when air no longer behaved as a compressible fluid.
- The critical Mach number of the Spitfire's original elliptical wing was higher than the subsequently used laminar-flow-section, straight-tapering-planform wing of the follow-on Supermarine Spiteful, Attacker, illustrating that Reginald Mitchell's practical engineering approach to the problems of high-speed flight had paid off.
