绿色、环保理念在飞机设计制造中主要表现为解决噪声问题和尾气排放问题。而噪声问题因直接影响舱内乘客的乘坐舒适性,并同时影响飞行路线中的外部环境,而备受关注。我记得,欧洲制造的超音速飞机当时在美国就遭遇禁飞的情况,主要是因为它在飞行过程中,给外部环境带来巨大噪声。 Green, environmental protection concept in the aircraft design and manufacture mainly to solve the noise problem and exhaust emissions. Concerns have been raised about noise issues that directly affect the ride comfort of passengers in the cabin and affect the external environment in the flight path at the same time. I recall that the European-made supersonic aircraft was encountered in the United States at no-fly, mainly because it caused huge noise to the external environment during the flight.
