ATO # 92 - January 14, 2000
QuestChats require pre-registration. Unless otherwise noted, registration is at: http://quest.arc.nasa.gov/aero/chats/#chatting Tuesday, January 18, 2000, 10 AM - 11 AM Pacific Aerospace Team Online QuestChat with Larry Young Larry is a researcher who studies helicopters and tiltrotor airplanes. He tries to make them quieter so they can help solve airport congestion. He also brainstorms ideas for helicopters in space! Tuesday, January 25, 2000, 10:30 AM -11:30 AM Pacific Aerospace Team Online QuestChat with Gavin Botha Not only does Gavin have lots of experience with low speed aerodynamics, he also flys radio operated sailplanes.
Sneak preview the "Regimes of Flight" a new resource for targeted for grades 4-8. You will find background material, lesson plans, chats and contests!! For more information see http://quest.arc.nasa.gov/aero/events The Website will officially open in two weeks.
[Editors Note: Larry A. Young is an aeromechanics engineer. He is looking for ways to make civil tiltrotors quieter. Read his biography at http://quest.arc.nasa.gov/aero/team/young.html ]
LATEST WIND TUNNEL TEST TO ADVANCE CIVIL TILTROTOR TECHNOLOGY
December 29, 1999 Just before the holidays, on December 21, 1999, NASA Ames engineers and technical support personnel installed the Full-Span Tilt Rotor Aeroacoustic Model (FS TRAM) in the 40-by-80 Foot test section of the National Full-scale Aerodynamics Complex (NFAC). The NFAC, located at NASA Ames Research Center at Moffett Field, CA, is a world premier low-speed aerodynamics and acoustics research facility, and boasts, in addition to the 40-by-80 test section, the world's largest wind tunnel test section (the 80-by-120 Foot Wind Tunnel). TRAM is a newly developed research facility that will enable the improved understanding and advancement of tiltrotor technology, with emphasis on noise reduction for a future generation of civil tiltrotor aircraft. TRAM is two test stands in one: an isolated rotor configuration, which has been previously tested in the Duits-Nederlandse Windtunnel in The Netherlands in 1998 (when the NFAC was undergoing an acoustic modification/upgrade), and a Full-Span configuration, which will be tested for the first time in the NFAC. In its full-span configuration (dual rotors with an airframe) the TRAM is approximately a 1/4-scale representation of the Bell-Boeing V-22 Osprey tiltrotor. After baseline aeroacoustic testing in the NFAC in 2000, advanced quiet rotors will be tested in later years on the full-span TRAM test stand. Hopefully one day, in part through the successful efforts of the TRAM test team, taking a ride home for the holidays on a civil tiltrotor aircraft will be a commonplace event.
