Abstract

　公知の機構を利用することにより航空機の離着陸時の地上におけるエンジン騒音を大幅に低減することが可能な低騒音航空機を提供する。 　公知の機構で構成された推力の方向を可変にする推力偏向手段を利用して、エンジンのジェット排気騒音の最大伝播方向を地上から遠ざけるようにエンジンの排気方向を航空機の経路方向（飛行方向）に関して上側（上方）になるように偏向することにより、航空機の離着陸時の地上におけるエンジン騒音レベルを低減する。特に、推力偏向式排気ノズル２０が上部偏向ノズル２１および下部偏向ノズル２２によって構成されている場合は、着陸滑走時において、エンジンに逆推力を発生させることが出来るようになる。
