| description | Embodiments of the invention relate to a supersonic inlet employing relaxed isentropic compression to improve net propulsive force by shaping the compression surface of the inlet. Relaxed isentropic compression shaping of the inlet compression surface functions to reduce cowl lip surface angles, thereby improving inlet drag characteristics and interference drag characteristics. Using supersonic inlets in accordance with the invention also demonstrated reductions in peak sonic boom overpressure while maintaining performance.
Des modes de réalisation de linvention concernent une entrée dair supersonique mettant en uvre une compression isentropique relâchée pour améliorer la force de propulsion nette par façonnage de la surface de compression de lentrée dair. Le façonnage de la compression isentropique relâchée de la surface de compression de lentrée dair permet de réduire les angles de surface de bord dattaque capot, ce qui améliore les caractéristiques de traînée dentrée dair et les caractéristiques de traînée dinterférence. Lutilisation dentrées dair supersoniques selon linvention permet également de réduire la surpression de bang sonique maximum, tout en conservant les performances. |
