Tailless supersonic plane revived

first_imgEDWARDS AIR FORCE BASE – The Defense Department is revisiting a page out of NASA Dryden’s past to check out the viability of an unusual airplane design for future long-range military jets. The oblique flying wing would be a tailless, supersonic airplane with a “scissors” wing in which one wingtip points forward and the other back at high speed – reducing drag and letting it fly fast on less power. “What we envision is an X-plane program,” said Thomas Beutner, program of the Defense Advanced Research Projects Agency. “Like the X-1 or the X-29, the Oblique Flying Wing program will be a technology demonstrator that explores a concept that can only be proven in flight.” Northrop Grumman is working on a $10.3 million DARPA contract for preliminary design and risk reduction work on the aircraft design.

The oblique-wing design concept is attributed to the late Robert T. Jones, a NASA aeronautical engineer credited with advancing the idea of swept wing aircraft in the 1940s. Jones believed that an oblique wing supersonic transport aircraft might achieve twice the fuel economy of an airplane with conventional wings. “One of the things he was interested in was a plane with wings that pivoted,” said Alex “Skip” Sim, a former NASA Dryden engineer. “As a young engineer at the time, I was intrigued by it.” NASA’s own low-speed oblique-wing airplane, the AD-1, flew in the late 1970s and early 1980s at Dryden Flight Research Center. Burt Rutan, who would later gain fame with the Voyager aircraft and SpaceShipOne, contributed to the aircraft’s design. Dryden project participants described the project as a low-cost, simple effort. The airplane was built under a $240,000 contract. “When we built the AD-1, we were not able to find funding for an airplane to go into a supersonic flight regime. What we could do with the money we had was look at handling qualities at slow speeds,” said Sim, who worked on the AD-1. “AD-1 was a handling qualities test – to see from a pilot’s perspective how it would fly.” The twin-engine jet had an electronically driven mechanism that would slowly pivot the wings. The wing could pivot to as much as 60 degrees. The airplane was flown 79 times during a roughly three-year period. The angle of the pivot on the aircraft was slowly increased during the course of the flight test program until it reached the full 60 degrees. “The side forces are very significant once you get past 45 degrees,” said Tom McMurtry, a retired NASA test pilot who was the AD-1 project pilot. “It was not a nice flying airplane.” Jones considered the oblique wing a viable concept after the flight testing, but the aviation industry was cool to the idea, perhaps because of the AD-1’s poor flying qualities. McMurtry and Sim said the AD-1 had a very simple mechanical flight control system and the poor flying could have been addressed in a more sophisticated airplane. “I would have liked to have seen a high-speed demonstrator built, but at the time we couldn’t find the funds within the agency,” Sim said. McMurtry said he was not surprised at the renewed interest in the concept. “I wish them well,” McMurtry said of the DARPA effort. In announcing the contract award, DARPA acknowledged the NASA AD-1 effort and previous engineering studies on the concept. However, DARPA pointed out that no one has attempted high-speed flight and that their concept calls for a tailless aircraft.

Bono To Be Honored By Nile Rodgers We Are Family Foundation

first_imgTo purchase tickets, or to make a contribution to the We Are Family Foundation, please visit wearefamilyfoundation.org. Contributions are fully tax-deductible to the extent allowed by law.Arrivals and reception begin at 6:30pm on Friday, April 29, 2016 followed by the awards ceremony, dinner and live concert with Nile Rodgers & CHIC and Bono beginning at 7:30pm at the Manhattan Center’s Hammerstein Ballroom located at 311 West 34th Street in New York City. On Friday, April 29, 2016, the We Are Family Foundation (WAFF), a not-for-profit organization founded by legendary GRAMMY Award winning musician, Nile Rodgers, will honor Bono at Manhattan Center’s Hammerstein Ballroom in New York City.Bono will receive the We Are Family Foundation Humanitarian Award, which honors a person in the public eye who has made tremendous efforts and inroads into making the human condition better throughout the world. The lead singer of the iconic and award-winning band U2, Bono is also a long-time activist in the fight against AIDS and extreme poverty in Africa. He is the cofounder of ONE, a global advocacy and campaigning organization and (RED) which works with companies to raise awareness and funds for the fight against AIDS. Previous recipients of the WAFF Humanitarian Award have included Sir Elton John, Sting & Trudie Styler, Steven Van Zandt, Nile Rodgers, Jackson Browne and Peter Gabriel.“The DNA of musicians in general is to give the gift of music to people around the world. And, in times of tragedy, musicians are the first to organize and give their music and themselves to help raise awareness, funds and in many cases a place to start to heal. For decades Bono’s passion for humanity continues through his work as a voice to solve some of our biggest issues on a global scale. I am proud to have him as this year’s We Are Family Foundation Humanitarian honoree, and I’m honored to call him a friend.” says WAFF Founder & Chairman, Nile Rodgers.The funds raised will support WAFF’s mission and programs including WAFF’s signature program, Three Dot Dash, which identifies, supports and mentors Global Teen Leaders actively working on programs that address basic human needs and promoting a more peaceful world; and TEDxTeen, a global educational platform for extraordinary teenagers to share their ideas, stories and inspire millions.last_img read more
