![]() Aerovironment gave a high altitude solar powered aircraft a shot. Now Boeing is going to give it a go. Boeing Awarded DARPA Contract to Develop Ultra-Long-Endurance Aircraft Technologies Vulture is an ultra-long-endurance aircraft that could stay aloft for several years and serve as a pseudo-satellite system. (Neg#: 080421d) ST. LOUIS, April 21, 2008 -- Boeing [NYSE: BA] has been awarded a $3.8 million Defense Advanced Research Projects Agency (DARPA) contract for Phase 1 of the Vulture air vehicle program, an effort to create a new category of ultra-long-endurance aircraft. DARPA's Vulture program calls for developing technologies and ultimately a vehicle that can deliver and maintain an airborne payload on station for an uninterrupted period of more than five years using a fixed-wing aircraft. Boeing is teaming with United Kingdom-based QinetiQ Ltd. for the program. The yearlong Phase 1 covers conceptual system definition, and formal reliability and mission success analysis, concluding with a System Requirements Review. It also requires conceptual designs for sub- and full-scale demonstrators. "Boeing has worked closely with DARPA on a number of innovative programs in the past and we welcome this important opportunity to again team with them to define a new air vehicle system with unprecedented reliability and endurance that significantly extends current aircraft and spacecraft capabilities," said Pat O'Neil, program manager, Boeing High Altitude Long Endurance Systems. "We will combine our strengths in highly reliable aerospace systems development with the unique capabilities of our teammates, QinetiQ, Versa Power Systems and Draper Laboratory." QinetiQ is currently flying and testing a solar-powered, high-altitude, long-endurance unmanned aerial system for the U.K. Ministry of Defense and the U.S. Department of Defense under the Zephyr Joint Capabilities Technology Demonstration. QinetiQ's role will be to leverage the technologies developed and demonstrated in Zephyr for the DARPA Vulture program. The Vulture vehicle's goal is to be capable of carrying a 1,000-pound, 5-kilowatt payload and have a 99 percent probability of maintaining its on-station position. The project is a collaborative effort led by Integrated Defense Systems (IDS) Advanced Systems, working with Boeing Phantom Works, Boeing Spectrolab and IDS Space and Intelligence Systems. Currently the only systems capable of providing multiple years of coverage over a fixed area are geosynchronous satellites orbiting 22,233 miles above Earth. "Such a 'pseudo-satellite' system, like Vulture, could provide compelling operational advantages in terms of persistent intelligence, surveillance, reconnaissance and communications," said O'Neil. |

If you learn anything interesting, please post it. http://www.advanced-composites.com/n...ve/zephyr-uav/ With weight restrictions being a critical element in the design of Unmanned Air Vehicles (UAVs), QinetiQ's solar and battery powered Zephyr UAV, which was designed with structural and manufacturing input from B3 Technologies Ltd., utilised ACG's flexible project approach and received appropriate application specific materials manufactured to their own exacting specifications. Ultra-light glass skins were combined with the ultra-high modulus carbon fibre to achieve stringent structural and weight requirements. With significant previous experience in the application of carbon composites to the manufacture of UAVs, ACG's pre-impregnated composite materials (prepregs) were expertly applied by B3 Technologies to the manufacture of structural elements and other components, taking QinetiQ's lightweight (sub-30kg [66lb]) 12metre wing span Zephyr to a platform record height and duration during its most recent flight trials. Founded by John Barnard, long recognised as one of the world's most influential racing car designers, with decades of top level motor racing experience, B3 Technologies specialises in creating the finest components for high performance applications and embraces an immense understanding of the capabilities and applications of advanced composites materials. That's exactly why QinetiQ turned to B3 Technologies and made them a subcontractor for the development of their Zephyr UAV. Previous developments saw earlier models of the Zephyr reach a significant height. Advances in the development of the latest variant culminated in a flight time of 18 hours and an altitude of 36,000ft, with a target altitude of 50,000ft well within its reach. Solar power was used for the ascent, reverting to batteries during dusk, which provided a further 7 hours thereafter, emphatically proving the concept. The combination of solar panels on the upper wing surface and rechargeable batteries is expected to allow Zephyr to be flown for months at a time. The application of ACG's carbon composites for the manufacture of single piece 'D' section wing spars resulted in lighter and structurally superior components, which contributed to an overall weight reduction. One of many different parts B3 Technologies produced for the UAV, and perhaps the most impressive, is the propeller. Being extraordinarily light and almost 1 metre long, it comes out of the mould almost perfectly balanced; such is the accuracy of B3 Technologies manufacturing method applied to ACG's prepreg materials. QinetiQ foresees a wide range of civil, defence and security applications for Zephyr, including surveillance, remote sensing, communications and atmospheric sensing. The aircraft has recently been selected as the platform for the Belgian Mercator HALE UAV system, a remote sensing demonstrator that will be used for mapping. http://cc.msnscache.com/cache.aspx?q...a8a&FORM=CVRE9 http://www.boeing.com/ids/news/2008/q2/080421d_nr.html http://www.afcea.org/signal/articles...wer.asp?a=1441 http://www.defenselink.mil/releases/...eleaseid=11647 Zephyr — Joint, real-time, battlefield persistent surveillance and communications via an extended-duration, solar-powered, unmanned aerial vehicle Combatant Command/User Sponsor: USCENTCOM and USEUCOM Transition Service/Agency: TBD Project Oversight: OSD/DDR&E/AS&C http://www.acq.osd.mil/jctd/descript.htm Zephyr Demonstrates a solar-powered unmanned aerial vehicle to meet urgent operational requirements for USCENTCOM and USEUCOM. Provides low-cost persistent surveillance and communications relay, flying continuous operations for periods of months at a time using solar power plus batteries for continual day/night operations. Sensors enable ground radio communications links over hundreds of square miles and surveillance of logistics routes and ground threats. Hand-launched UAV requires no formal infrastructure and little manpower to operate and provides cross-theatre benefits to all U.S. Forces. http://www.luchtzak.be/news/boeing/ |
