The first flight provided data in aerodynamics and flight performance, while the second provided information about structures and high temperatures. [3], Built by Lockheed Martin Corp, the HTV-2 is made of carbon composite material; the durability of such material was needed to prevent important internal components from being destroyed because they are a few inches from its surface. [3][10][11] In mid-November, DARPA stated that the first test flight ended when the computer autopilot "commanded flight termination" after the vehicle began to roll violently. [1][2] Das HTV-2 wurde von Lockheed Martin gebaut. It is a test bed for technologies to provide the United States with the capability to reach any target in the world within one hour using an unmanned hypersonic bomber aircraft. Several recent analy- ses of its flight characteristics … Un article de Wikipédia, l'encyclopédie libre. Le Hypersonic Technology Vehicle 2 (HTV-2) est un planeur hypersonique sans pilote[1] capable d'atteindre Mach 20[2]. The Defense Advanced Research Projects Agency (DARPA) and United States Air Force (USAF) conducted two experimental flight tests of the Hypersonic Technology Vehicle 2 (HTV-2). [4] The various departments involved in designing the vehicle included aerothermodynamics, materials science, hypersonic navigation, guidance and control systems, endo- and exo-atmospheric flight dynamics, telemetry and range safety analysis. [3] Both these missions are funded by the US Defense Advanced Research Projects Agency (DARPA) to help develop hypersonic technologies and to demonstrate its effectiveness. Defense Advanced Research Projects Agency’s (DARPA) Falcon Hypersonic Technology Vehicle 2 (HTV-2) program is focused on making the long-duration hypersonic flight a reality. Technology trends and related opportunity for new Hypersonic Missiles Market tech suppliers 4. … Initial reports indicated it purposely impacted the Pacific Ocean along its planned flight path as a safety precaution. The surface temperature of the HTV-2 was expected to reach 1,930 °C (3,500 °F) or more in flight; steel melts at 1,370 °C (2,500 °F).[7]. Recent US industry focus has been on avionics, stealth, and methods of making the last generation of aircraft more effective. [1][3] Contact was lost with the vehicle at nine minutes into the 30-minute mission, and the glider's skin disintegrated. Both HTV-2 missions would be launched from Vandenberg Air Force Base, California, using existing rocket booster systems. Following The notional glide vehicle modeled here is based on the Hypersonic Technology Vehicle 2 (HTV-2), an experimental glider jointly developed and tested by the U.S. Air Force and the Defense Advanced Research Projects Agency (DARPA).16 This system is commonly considered a proto-typical intercontinental-range hypersonic glide vehicle. They see the emerging arms, which can deliver nuclear or conventional munitions, as zipping along at up to five miles a second while zigzagging through the atmosphere to outwit early-warning satellites and interceptors. This EA documents the potential environmental impacts of conducting two Hypersonic Technology Vehicle 2 (HTV-2) flight tests to support development and demonstration of hypersonic technologies. [1][2] It is a test bed for technologies to provide the United States with the capability to reach any target in the world within one hour (Prompt Global Strike) using an unmanned hypersonic bomber aircraft. [4] Under the original plan, HTV-1 was to feature a hypersonic lift-to-drag ratio of 2.5, increasing to 3.5-4 for the HTV-2 and 4-5 for the HTV-3. Experience gained from the HTV-2 will be used to improve hypersonic flight. [6], Development of protection structures that are tough and lightweight, development of an aerodynamic shape that has a high lift to drag ratio, development of automatic navigation control systems etc. The Navy originally hoped to apply the HyFly technology to a hypersonic cruise missile optimized for the carrier-based Boeing F/A-18E/F. At Mach 20, is the Falcon Hypersonic Technology Vehicle 2 a faster 'Aurora'? The hypersonic combustion … Vous pouvez partager vos connaissances en l’améliorant (comment ?) [14][15][16] The glider's surface reached 1,930 °C (3,500 °F) (the speed and heat caused part of the skin to peel away from the aerostructure[7]) and controlled itself for 3 minutes before crashing.[17]. HTV-2 is an unmanned, rocket-launched, maneuverable aircraft that glides through the Earth’s atmosphere at incredibly fast speeds — Mach 20 (approximately 13,000 miles per hour), the DARPA website says. The flight plan called for the craft to separate from the launch vehicle, level out and glide above the Pacific at Mach 20. The unmanned Falcon HTV-2 successfully separated from the booster and entered the mission's glide phase, but again lost contact with control about nine minutes into its planned 30-minute Mach 20 glide flight.
