31. Comparison of drag characteristics of various nose cone shapes in the transonic to low-mach regions. 32. In this example the turbine is a transonic unit, where the throat Mach number reaches choked. 33. It was also adapted to the transonic and ultrasonic regions with a device called " Transonic ". 34. It was also adapted to the transonic and ultrasonic regions with a device called " Transonic ". 35. The Transonic Dynamics Wind Tunnel now used exclusively for aeroelastic research is based on the same principles. 36. The transonic regime " is inherently messy and always a problem, even for aircraft," 37. He reached this speed at less than full throttle, as he was concerned by the transonic buffeting. 38. Sweep theory helps mitigate the effects of compressibility in transonic and supersonic aircraft because of the reduced pressures. 39. Thus a long span, valuable at low speeds, causes excessive drag at transonic and supersonic speeds. 40. Casting about for other research, he returned to the question of transonic drag, especially on wings.
