Primer vuelo hipersónico del X-51/X-51A will make its first hypersonic flight test
Si las condiciones meteorológicas no lo impiden, el demostrador de vuelos hipersónicos X-51A Waverider realizará su primer vuelo el proximo 25 de mayo de 2010, lanzado desde un B-52 desde las costas del Sureste de California.
Se prevee que su vuelo dure cinco minutos y que acelere hasta Mach 6, transmitiendo gran cantidad de datos a estaciones en tierra, antes de caer en el Pacífico. No hay planes de recuperar el vehículo. En esos cinco minutos se espera obtener mas información que en todos las pruebas anteriores. El vuelo hipersónico mas largo realizado anteriormente con un motor de propulsión a chorro, fue realizado por la NASA, con el vehículo X-43, fué mas rápido pero solo duró 10 segundos.
El X-51A es fruto de la colaboración entre la USAF, Boeing Company, Pratt & Whitney, y otros organismos gubernamentales. Un P-3 Orion de la US Navy ayudará en la transmisión de datos. Este será el tercer vuelo del X-51 que ya lo ha hecho anteriormente fijado en los pilones alares de sujección de un B-52.

__________________________________________
Weather permitting, Air Force officials said the X-51A Waverider will make its first hypersonic flight test attempt May 25 after it is released from a B-52 Stratofortress off the southern coast of California.
The unmanned X-51A is expected to fly autonomously for five minutes, powered by a supersonic combustion scramjet engine, accelerating to about Mach 6 and transmitting vast amounts of data to ground stations before breaking up after splashing down into the Pacific, as planned. There are no plans to recover the flight test vehicle, one of four built. In those 300 seconds, it is hoped to learn more about hypersonic flight with a practical scramjet engine than all previous flight tests combined.
The longest previous hypersonic scramjet flight test performed by a NASA X-43 in 2004was faster, but lasted only about 10 seconds.
The X-51A program is a collaborative effort by representatives from the Air Force Research Laboratory and the Defense Advanced Research Projects Agency, with industry partners The Boeing Company and Pratt & Whitney Rocketdyne.
A U.S. Navy P-3 Orion will aid in transmitting telemetry data.
The May 25 hypersonic test will actually be the third time the X-51 has flown, but in each previous instance it has remained attached to the B-52's wing.
