Almost 12 years have passed since the last flight of the legendary Concorde, which, however, did not mean the end of the supersonic era of civil aviation. As it became known, NASA allocated 2.3 million dollars for the development of a new generation supersonic passenger airliner.
It is assumed that these funds will be spent on eight research projects to solve technical problems related to the behavior of supersonic aircraft in the stratosphere and the noise generated by them in order to reduce it.
It is well known how powerful, thunderous is the sound wave at the moment the plane crosses the sound barrier, which is the main problem for the nearby settlements. The developers will also have to tackle the minimization of exhaust emissions at high altitude and the economy of the engines.
One of the leading participants in the project, the Massachusetts Institute of Technology, will deal with issues related to the impact of the new aircraft on the environment, taking into account the experience of previously created supersonic aircraft of the SR-71 type.
Scientists, in particular, have to find out what effect the appearance of a whole fleet of supersonic passenger liners will have on the state of the ozone layer. As part of a separate project - the development of a so-called hybrid wing that fits perfectly into the airframe, which significantly improves aerodynamics and reduces fuel consumption.
