NASA To Build Supersonic Aircraft - Flight Speed Is Five Times The Speed Of Sound

According to foreign media reports, NASA intends to manufacture in the Earth's atmosphere, the supersonic jet flight, the aircraft's flight speed is 5 times the speed of sound, thus greatly reducing the time to fly around the world, can be reduced up to several hours.

At this speed flight from New York to Sydney, only about 2 and a half hours, and now requires 21 hours flight. It is believed that the project is to fly to Mars in order to create a reusable aircraft, however, the use of the previous space technology, it is possible to have a tremendous impact passenger. According to NASA's Aviation 2010 recommendations, the council each year out of $ 5,000,000 to be allocated over the next 3 years to a new aircraft into reality. Goal is to develop a passenger can carry through the atmosphere, and safe landing of aircraft can be reused.

The Space Concorde: NASA Pushes For Extraterrestrial Hypersonic Flight

NASA is looking for a way to get into space without having to use those pesky, bulky rockets. That means hypersonic travel, which was added to NASA’s Aeronautics 2010 proposal solicitation yesterday. The type of craft that NASA's hoping for would be able to fly at five times the speed of sound - fast enough to make the jaunt from New York to Sydney in two and a half hours. We've seen some exciting hypersonic concepts before, as well as an unfortunate failure from DARPA, but with NASA money behind the research, extraterrestrial hypersonic flight could really get somewhere.

Movement Of Centre Of Pressure

When any aircraft passes the critical mach of that particular airframe, the centre of pressure shifts rearwards. This causes a pitch down force on the aircraft, as the centre of mass remains where it was. The engineers designed Concorde's wings in a specific manner to reduce this shift. However, there was still a shift of about 2 metres. This could have been countered by the use of trim controls, but at such high speeds this would have caused a dramatic increase in the drag on the aircraft. Instead, the distribution of fuel along the aircraft was shifted during acceleration and deceleration to move the centre of mass, effectively acting as an auxiliary trim control.

Concorde Could Become Thameside Attraction

A decommissioned Concorde jet currently languishing at Heathrow airport could get an unlikely lease of life, as a new tourist attraction on the Thames.
