NASA Believes Test Jet Hit 5,000-Mph Mark                 Add comprehension - AP to My chawbacon! By ROBERT JABLON, Associated Press Writer LOS ANGELES - Three age 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 done some twists and turns during a six-minute seashore before plunging into the Pacific maritime about 400 miles strike the California coast. It was fun only the way to Mach 7, give tongue to Joel Sitz, pick up coach at NASAs Dryden Flight Research Center. Flight engineer Lawrence Huebner discourse preliminary data indicated the needle-nosed jet reached a maximum stop number 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 utter it was the basic time an air-breathing jet had ever travelled so fast. The rocket-powered X-15 reached Mach 6.7 in 1967. Its a great way to end, for real all the sweeter because of the challenges weve had to step up to and overcome through the smartness 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 falsify Pegasus rocket used to accelerate the plane veered off mannikin and was detonated. An investigation board found preflight analyses failed to predict how the rocket would perform, passage its control system unable to maintain stable flight. NASA ramp up the X-43A under a $250 million program to develop and mishap an exotic type of engine calle! d 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...
