Mark, That is fantastic! I know some rotorcraft engineers who might really like to rediscover that report!Mark Nankivil said:Hi Stargazer2006 -
I cannot find any Boeing Vertol project number assigned to the project or at least mentioned in the report. Yastotay, at some point I'll take it apart and copy/scan it. You'll be one of the first to know when I get that done.
I've attached a scan of the report description page if someone is in a position to track down Volume 2 or other documentation related to ACAP.
Enjoy the Day! Mark
Interesting. Are you saying that the S-75 design involved Northrop at some point, or was it a separate design?BillRo said:When you look at one of the Sikorsky drop test vehicles it has a noticeable chine that is not apparent in the drawings. That may be because Sikorsky would also have been asked for a design with reduced signature. It may not be a coincidence that at the time Northrop white world advanced design were asked to study a helicopter with reduced RCS for Sikorsky. We thought that an unusual request since helicopter engineers and aircraft engineers never mix. We gave the job to John B., one of our most creative configurators, and he came up with something that, although not as radical as the Boeing low RCS design, had significant shaping. It got sent off to them and we heard no more. Sorry no drawings.
Possibly. Most low observable helicopters, real or the ones that exist only as proposals, appear to feature a fuselage with slanted sides. The aviation press seem to have concentrated on fixed-wing stealth aircraft but LO heliccopters are worthy of some investigation. Hopefully some of the older classified programmes come out of the dark soon.litzj said:Could this project affect the modified version of UH-60 for Bin Laden Hunt?
