Noise and fuel consumption reducing method for e.g. silent supersonic cargo aircraft, involves adjusting supersonic and subsonic engines, deployed scoops, and retractable air blowers, based on different flight phases

摘要

The method involves adjusting fixed supersonic turbojet engines (21, 22) with a low dilution rate, left and right retractable or fixed subsonic turbojet engines (11, 12) with a low dilution rate, a deployed left scoop (41), a deployed right scoop and additional left and right retractable air blowers (31, 32), based on different flight phases such as supersonic and subsonic phases. The left and right air blowers are actuated by drawing of energy on the engines (11, 12).
