LOS ANGELES - Three years after its offset see flight ended in an explosion, NASA on Saturday successfully launched an experimental jet that the agency believes reached a record-setting velocity of about 5,000 mph.
The unpiloted X-43A do an 11-second powered flight, then went through some twists and turns during a six-minute seashore before plunging into the Pacific Ocean about 400 miles strike the California coast.
It was fun all the way to Mach 7, give tongue to Joel Sitz, pick up manager at NASAs Dryden Flight Research Center.
Flight engineer Lawrence Huebner utter preliminary data indicated the needle-nosed jet reached a maximum speed of slightly over seven times the speed of sound, or about 5,000 mph, after a rocket boosted it to about 3,500 mph.
Huebner said it was the first time an air-breathing jet had ever traveled so fast. The rocket-powered X-15 reached Mach 6.7 in 1967.
Its a great way to end, for certain all the sweeter because of the challenges weve had to step up to and overcome through the liveliness of this project, said Griffin Corpening, Drydens chief engineer on the project.
The first X-43A flight ended in failure June 2, 2001, after the modify Pegasus rocket used to accelerate the plane veered off shape and was detonated. An investigation board found preflight analyses failed to predict how the rocket would perform, loss its control system unable to maintain stable flight.
NASA construct the X-43A under a $250 million program to develop and visitation an exotic type of engine called a supersonic-combustion ramjet, or scramjet.
In theory, the air-breathing engine could propel an airplane to speeds of Mach 7 or faster, change around-the-world flights that would take...
