| 31. | It is designed to fly at subsonic speeds and photograph the earth from above 60, 000 feet.
|
| 32. | Variable geometry would improve maneuverability at subsonic speed, but at the cost of decreased fuel tank capacity.
|
| 33. | Because of noise restrictions, it operated at subsonic speeds between Dallas-Fort Worth Airport and Washington's Dulles Airport.
|
| 34. | The termination shock is the point in the heliosphere where the solar wind slows down to subsonic speed.
|
| 35. | At low speeds ( subsonic speeds ) increases in static pressure are however limited to a few percent.
|
| 36. | Boeing designed the plane to have a 750-mile ( 1, 200-kilometer ) range and fly at subsonic speeds.
|
| 37. | Thus, scramjets do not have the diffuser required by ramjets to slow the incoming airflow to subsonic speeds.
|
| 38. | This led into a single large duct with three-part variable-profile walls that slowed the intake air to subsonic speeds.
|
| 39. | Although I never heard of any subsonic speed that allows that, I'm not sure whether 2 Mach is mandatory.
|
| 40. | The only wasted sound power is that emitted radially ( and, at subsonic speed, forwards ) from the engine.
