SAN FRANCISCO, Nov. 8, 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 global flight time can be reduced up to several hours.
At this speed flight from New York to Sydney, coach bags 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.
Under this proposal, engineers need to address the massive vehicle down into the planet's atmosphere and landing and suction and exhaust
problems in space.coach bags sale NASA is also very clear that many challenges facing the
development of this machine. NASA said in the proposal: "hypersonic heating environment, coupled with the need to have reusable performance,
making the R & D work in materials, coatings and structural design, materials, face several technical challenges, which not only able to
withstand the aerodynamic loads, and the need to repeat withstand high heat loads, while ensuring the lightest body, but also to ensure long
life and durability. in order to achieve cost access to space, launch vehicles must be very lightweight, reusable and easy to maintain. "
In contrast, most following the Concorde supersonic aircraft after a new concept, the flight speed of Concorde 2 times the speed of sound,
and hypersonic aircraft, speed can reach 5 times the speed of sound.
June of this year,discount coach handbags a scramjet test plane used to create hypersonic flight
recorders ---- 6 times the speed of sound in the air with a 3 minute flight, the equivalent of 4,500 miles per hour (7242.05 kilometers).
"X-51A WaveRider" extremely scramjet aircraft last week from a B-52 bombers on the release of the engine on their own, to 6 times the speed
of sound 200 seconds of flight itself, the working principle of this aircraft is carrying its own oxygen into the engine at supersonic
speeds, light hydrogen fuel to produce power.
October this year, Richard Branson's Virgin Galactic spaceship 2, was developed by the mothership sent over 45,000 feet Mojave Desert (13.72
km) altitude, successfully completed its maiden voyage.discount coach boots The aircraft designed
by the famous aircraft designer Burt Rutan, the purpose is to allow more people an acceptable price for space travel, the current fare is $
200,000. It was in 2004, $ 10,000,000 received a bonus based on the prototype developed, can take six passengers, but need to go through a
series of rigorous testing before they can put the passengers into space. (Qiu Ling)
