SUPERSONIC AIRCRAFT WITH ACTIVE LIFT DISTRIBUTION CONTROL FOR REDUCING SONIC BOOM |
摘要 |
<p>Methods and systems for actively reducing sonic boom in commercial supersonic aircraft and other supersonic aircraft are described herein. A method for operating an aircraft in accordance with one aspect of the invention includes configuring at least one lift control device to produce a first streamwise lift distribution, and flying the aircraft at a subsonic speed while the lift control device is configured to produce the first streamwise lift distribution. The method can further include configuring the lift control device to produce a second streamwise lift distribution, and flying the aircraft at a supersonic speed while the lift control device is configured to produce the second streamwise lift distribution. The first streamwise lift distribution produces an N-shaped ground pressure signature and a corresponding first sonic boom at the supersonic speed. The second streamwise lift distribution, however, produces a "shaped" ground pressure signature and a corresponding second sonic boom that is less than the first sonic boom at the supersonic speed.</p> |
