transonics การใช้

• Kriging surrogate model of the drag coefficient of a transonic airfoil.
• GEK surrogate model of the drag coefficient of a transonic airfoil.
• The NACA area rule is one approach to reducing transonic interference drag.
• The'fix'is similar to that of transonic wing design.
• Passenger aircraft ( with exception of Concord ) are sub or transonic.
• Can you control the vehicle as it goes from transonic to sonic speeds?
• Most modern jet powered aircraft are engineered to operate at transonic air speeds.
• Work began in July 2011 to remove the 1940s era transonic wind tunnel.
• At even higher speeds in the transonic, wave drag enters the picture.
• These problems were eventually solved as jet aircraft reached transonic and supersonic speeds.
• As an example, let us consider the flow over a transonic airfoil.
• The CF-103 offered improved transonic performance with supersonic abilities in a dive.
• The area rule concept is now used in designing all transonic and supersonic aircraft.
• Albert Betz immediately suggested the same effect would be equally useful in the transonic.
• Interestingly, all black hole accretions are transonic.
• The ambient air density has a significant effect on dynamic stability during transonic transition.
• Nimrod is transonic in operation and is powered all the way to the target.
• These shock waves, as in the transonic case, generate large amounts of drag.
• Severe instability can occur at transonic speeds.
• Aircraft flying at transonic speed often incur wave drag through the normal course of operation.
