Manuals of ALL types in the military became "more-serious" by the mid-50s, Air Force technical writing especially. (As the "New-service" I suppose it reflected a certain "need" to be MORE professional by being seriously, serious or some such)Stargazer2006 said:Here is a set of cartoons that were featured in Pilot's Handbook for the XB-35 heavy bombardment airplane and Handbook pilot's flight operating instructions for USAF series model YB-49 airplane (the latter from 1949).
It is nice to see that despite the high level of security and secrecy involved around the Northrop flying wings, the company was able to provide such light-hearted (albeit not very talented) illustration to two otherwise very technical reference manuals. Note how some of the artwork was subtly altered from the first to the second manual to reflect the change from propellers to jets.
Sadly, the 1950 Handbook flight operating instructions USAF series YRB-49A aircraft was already devoid of any amusing artwork... and flight manuals became serious ever since. :-[
Only marginally, as they wouldn't have been that much further back from the CG than the fins it already had. It's my understanding that Sperry had developed an FCS for the YRB-49 that solved the handling issues, which, IIRC, the major problem was the yaw oscillation, which I think might have been a very shallow dutch roll with a long period mode that couldn't be dampened out mechanically. I've not been able to get enough info, engineering wise, regarding it, I just remember one of the test pilots talking about the nose continually wandering back and forth slowly. He said it didn't really effect the way the plane flew as much as you couldn't exactly aim bombs precisely as a result, regarding the YB-49, not the YRB-49, in which case it would be the cameras.Stargazer2006 said:Wonder if wing-tip fins would have improved the handling... ???
Actually, no...no digital computers required, just a yaw damper channel through the autopilot. The contemporary B-47 required this fix for day-to-day flight (to cure a "dutch roll" problem) which was implemented by 1950-51. This could have been done for the B/RB-49 if it was desired by the customer - but the flying wing program was already on it's last legs.RanulfC said:While larger verticals MIGHT have helped with some issues it would take waiting for current active control computers to make the flying wings stable enough for real-world use.
LIFE *should* have a ton of really good photos. One of the time-life book series was full of photos of the -35 and -49 in various stages of construction.XB-70 Guy said:Here's some rare shots...
Ok yes there was and is still SOME humor, I recall an F-4 Phantom image that was used just about everywhere on maintenance documents that showed the pilot, the WO... then about a dozen "added-cockpits" down the spine listing each major contractor and system labeled "in-flight-support"The Artist said:There were some bits of humor here and there. A book on the F-86 line - Squadron Signal In Action Series, I believe - contained humorous presentations of information from the F-86D handbook. Then there is that illustration (which I do not have) showing an aircraft carrier being abandoned as a formation of USAF F-4s approach with gear and hooks down.
