11. As an example, let us consider the flow over a transonic airfoil. 12. The CF-103 offered improved transonic performance with supersonic abilities in a dive. 13. The area rule concept is now used in designing all transonic and supersonic aircraft. 14. Albert Betz immediately suggested the same effect would be equally useful in the transonic . 15. Interestingly, all black hole accretions are transonic . 16. The ambient air density has a significant effect on dynamic stability during transonic transition. 17. Nimrod is transonic in operation and is powered all the way to the target. 18. These shock waves, as in the transonic case, generate large amounts of drag. 19. Severe instability can occur at transonic speeds. 20. Aircraft flying at transonic speed often incur wave drag through the normal course of operation.
