Systems and methods for controlling a magnitude of a sonic boom

摘要

A system for controlling a magnitude of a sonic boom caused by off-design operation of a supersonic aircraft includes a sensor configured to detect a condition of the supersonic aircraft. The system further includes a control surface that is mounted to a wing of the supersonic aircraft. The system still further includes a processor communicatively coupled to the sensor and operatively coupled with the control surface. The processor is configured to (1) receive information from the sensor indicative of the condition of the supersonic aircraft, (2) determine that there is a deviation between a lift distribution and a design-condition lift distribution based on the information, and (3) control the control surface to move in a manner that reduces the deviation. The magnitude of the sonic boom is reduced when the deviation is reduced.

1. A system for controlling a magnitude of a sonic boom caused by operation of a supersonic aircraft at supersonic speeds, the system comprising:
a sensor configured to detect a condition of the supersonic aircraft; a control surface mounted to a wing of the supersonic aircraft; and a processor communicatively coupled to the sensor and operatively coupled with the control surface, the processor configured to:
receive information from the sensor indicative of the condition of the supersonic aircraft,determine that there is a deviation between a lift distribution and a design-condition lift distribution based, at least in part on the information, andcontrol the control surface to move in a manner that reduces the deviation, wherein the processor is configured to control the control surface in a manner that applies a torsion force to the wing, the torsion force causing the wing to twist in a nose-up direction when the processor determines that the condition of the supersonic aircraft will cause the wing to twist in a nose-down direction, and the torsion force causing the wing to twist in a nose-down direction when the processor determines that the condition of the supersonic aircraft will cause the wing to twist in a nose-up direction and wherein the condition comprises one of an off-design condition weight of the supersonic aircraft and an off-design condition velocity of the supersonic aircraft.
