Answer» What is Zero Emission Hyper Sonic Transport mean? The Zero Emission Hyper Sonic Transport or ZEHST is a planned hypersonic passenger jet airliner project by the multinational aerospace conglomerate EADS and the Japanese national space agency JAXA. On 18 June 2011, the ZEHST concept was unveiled by EADS at the Le Bourget Air Show. The envisioned vehicle uses a combination of three different types of engines, including relatively conventional turbofans, rocket motors, and scramjets to attain a maximum speed of Mach 4.5 (four and a half times the speed of sound). The ZEHST has been projected to carry between 50 and 100 passengers while flying at very high altitudes for greater efficiency. Conceptually, the ZEHST has been promoted as a descendant of, or a successor to, Concorde, a supersonic airliner that was withdrawn from passenger routes in 2003. According to projections released, the ZEHST would be capable of flying between Paris and Tokyo in 2.5 hours, or between New York and London within one hour. During 2011, EADS stated its prediction that the ZEHST could be flying by 2050. reference nan |
