Skybolt said:(...) And at page 306 a fine series of drawing of the B-36D carrier aircraft, for Archipeppe, in case he wanted to update his presentation rendering...

Uhm "suicide?" How so? It was well known that launching off the back of a delta-wing platform was relativly safe as long as positive control was maintained at all times between the launch vehicle and the launched vehicle. Due to the more pronounced "nose-up" atitude of the supersonic carrier aircraft there was also a much bigger "space" between the back of the aircraft and the "mach-shock" of the carrier aircraft than a bottom mount position. NASA did a study of using their own SR-71s to launch a fairly substantial sized test vehicle in the 90s and no issues were indicated.Orionblamblam said:CFE said:Did the XB-70 + X-15 combination ever make it as far as wind tunnel testing, or was the painting of the X-15 launching from the XB-70 merely a piece of PR artwork?
It was more PR than engineering. By that point, it was well known that launching something off the back of a Mach 3 plane was suicide.
There were also plans for launching from underneath a B-70 (such as the orbital X-15B proposal), but those would have required either landing gear modifications or launching from a trolley of some kind.
George Allegrezza said:The description is somewhat confusing. Is he saying it's a Topping X-15A3 or that he's modifying a Topping model to create an X-15A3?
Zeppelin said:What was the proposed use for this delta adaptation. Was it to be carried close to enemy borders ( halfway around the globe ) released to enter at high speed, deliver a payload/bomb on a city and have fuel to land.
These links don't seem to exist anymore - can someone help me find?Several photos of the single-fin wind-tunnel model are present on the NASA server (with the mention "Model in TBT-Transonic Blowdown Tunnel_, December 19, 1967") :
