Was the A-4b ever put in a wind tunnel?
I read about how the wings fell off after launch, and I read about how
it worked up to a point, but there's nothing about any drawings, static testing, or practically anything else. It seems that someone took a V-2, added the swept wings (apparently made just for the test), stretched the tail fins, and launched the thing. That doesn't seem to fit with what I think I know about Teutonic thoroughness or about the painstaking work to coerce the A-4 to fly. |

Teutonic thorougness decayed noticeably as the war progressed. The Peenemunde team had a hard time getting support for it, as the top brass wanted them to concentrate on other projects (like the Wasserfall SAM) rather than the A9 - which the A4b was a cover name for - to get it any funding. There is a surviving photo of a third A4b with enlarged control surfaces on its fins, and that one seems to have metal skinning on the wings, as its starboard aft wingtip is damaged...and it is wrinkled, not cracked like a all wooden wing would be.

They did indeed do supersonic wind tunnel tests on the design, and tried out several wing configurations in the wind tunnel before they built the prototypes. Got anything on the airfoil choice? Dimensions? The first one went out of control immediately after launch (there's surviving video of that, with the cameraman ducking as it goes crazy) The second one ascended correctly, but one of its wings fell off on the * descent. This was probably due to the heat and G loads it was encountering, and the fact that the wings were made of wood. That must have been hilarious, in retrospect. At the time, I'd have had to change, too. Mike |

Scott Lowther had a article that included info on this in one of his Aerospace Projects Review issues: http://www.up-ship.com/apr/v5n6.htm http://www.up-ship.com/apr/images/raumwaffearticle.gif I assume the airfoil profile had to be symmetrical to prevent the missile pulling to one side as it ascended due to the wing generating lift. That must have been hilarious, in retrospect. At the time, I'd have had to change, too. There were more than one film like that; here you can see why Peenemunde cameramen should have gotten combat pay: http://www.youtube.com/watch?v=WtjavGsYvao The one at the two minute mark went over the the adjoining Luftwaffe test center, who were not enthused by its arrival. I've never gotten specific figures on this, but apparently quite a few V-2 launch crews suffered fatalities as the missiles went out of control at launch; this was probably exacerbated by the fact that the concentration camp inmates working on the missiles discovered that you could urinate on the components of the guidance system as they were being made and they would still pass inspection, only to malfunction days later from the corrosive and gumming-up effects of the dried urine.
