ADTO # 68 - June 25, 1999
Have you always wanted to chat but not had time to practice or test it out? NASA QuestChat project manager, Oran Cox invites you to practice chatting with him. He's scheduled a practice chat for June 29, 1999 For more information visit: http://quest.arc.nasa.gov/qchats/
Prepare for the High Speed Civil Transport Test! Did you love following the Wright Flyer Wind Tunnel Test? Well we've got a great test coming up in July, 1999. It's another test of the model of the High Speed Civil Transport model that was tested here last in 1997. Future travelers may use this new type of aircraft, designed by NASA, to traverse the globe in a matter of hours. The High Speed Civil Transport promises to be the fastest airliner ever conceived, reaching speeds four times that of the Concorde, delivering passengers in Tokyo three hours after departure from San Francisco. Here's what you can do to get ready for this test: Read Mina Cappuccio's Profile: Mina is the main researcher on this test. http://quest.arc.nasa.gov/aero/team/cappuccio.html Read Fanny Zuniga's journals from the last HSCT test in the 12 foot pressure wind tunnel. Find out what happened the last time the HSCT model was here! http://quest.arc.nasa.gov/aero/events/test.html

I have been interested in aviation since I came to NASA twenty-five years ago. I have read a lot of books on aerodynamics and the equations of flight. I have had the opportunity to explore a lot of models. I read an article quite a few years ago in Scientific American about the Wright Flyer. I had forgotten some of the details I had forgotten that the canard was in front, and that the pilot just lies on the wings next to the engine. The Wright Flyer is very unstable. I am amazed that any one could fly it. With the control surfaces in front and the awkwardness of the control surfaces and the engine drive system is far from optimal. It's an engine driving two propellers with bicycle chains rather than a faster engine driving the shaft of the propeller. I was surprised how big the Wright Flyer was, with its forty-foot wingspan. I had touched cloth biplanes before that part wasn't new to me. The layout of the control surface and the engine layout were the big surprises to me.
