A couple of things that might interest this group: For those who just can't live without the sound of an SR-71 there is a sound effects CD with the sound of a fly-over offered by Bainbridge Records. The name of the CD is Sonic Booms 3 and has a picture of an SR on its cover. (I have no connection with this company nor do I even do business with them, I got on a mailing list) The June 1993 issue of Air International has part 1 of a multi part article analyzing the B-2. It goes into the history of stealth technology and has several paragraphs on the A-12/SR-71, application of RAM (Radar Absorbent Materials), and exterior shape for low RCS. There is a picture of 'Have Blue' the F-117A's prototype. On page 290 there is an interesting picture of an SR-71 in what appears a 60 +- degree right bank with vapor trails from the nose and leading edge of the wing outboard of the engine nacelles, there are two balls of flame approximately 15 feet aft of the aircraft, the caption suggests that the balls of flame are due to over enthusiastic throttle application at an airshow. The article ends with some discussion of the design criteria and a pen and ink cutaway drawing of the B-2. Sam ------------------------------ From: Brent L. Bates ViGYAN AAD/TAB Date: Mon, 21 Jun 93 14:23:12 EDT Subject: XB-70 & F-104 Crash (historical) Just recently the 7x10ft. transonic tunnel here at NASA-Langley was closed down, indefinitly. That in itself is not real relevant to this group, however, there was a get together this last weeked and all the retirees and current people were invited to talk about old times and see some OLD PHOTOS. One of the photos, dated 1966, was of a XB-70 AND F-104 models in the tunnel TOGETHER. Apparently Langley did some wind tunnel work on trying to find out why the XB-70 and F-104 crashed. I don't know any more. The picture reminded me of the discussion we had here on the skunk-works quite some time ago about the XB-70 it crash. Just thought I'd let this group know some wind tunnel tests had been done. I didn't realize it had been so long ago, utill I saw the 1966 photo. Brent L.

It would be interesting if someone could scan some of these pictures for the archives. Does anyone in this group have access to a good scanner? I'm working on it but so far, no go. Maybe in next years budget (yeah....sure) On another topic, has everyone seen this quarters Smithsonian Air and Space? Nice article on test pilots, then and now. I can add from limited personal experience in both my glider and homebuilt that getting the datapoints for instrument or airframe validation is pretty boring. It takes real discipline to keep yourself on the test card. Analyzing the data and improving the product is fun though. So is having your very own N number applied to a ship you built :-).
