TomPPL Posted January 8, 2009 Report Share Posted January 8, 2009 Here's something interesting a friend sent me recently, has anyone else out there heard of it?http://www.challis-heliplane.com/v3/ Quote Link to comment Share on other sites More sharing options...
heli.pilot Posted January 8, 2009 Report Share Posted January 8, 2009 (edited) I had heard the name before, but that was the first time I'd seen its design. Looks interesting with just the one wing! Having a single wing like that must have some CG implications. I would imagine that this would be cheaper than the X-2 design.

coloheli Posted January 8, 2009 Report Share Posted January 8, 2009 That is way cool. What class would that be? Semi-fixed Rotory Wing Quote Link to comment Share on other sites More sharing options...
charlicopter Posted January 8, 2009 Report Share Posted January 8, 2009 Hmmm.... I think it's a fun idea for RC... But for a full sized helicopter, how would you deal with the intense vibrations due to such intense and well-developed RBS? Can you believe the acceleration on that thing!?

PhotoFlyer Posted January 9, 2009 Report Share Posted January 9, 2009 This design will not eliminate RBS, but it will delay RBS. Put simply, the faster the A/C flies the more lift the wings (or wing) will produce. That lift will permit a lower pitch angle on the main rotor, thus delaying RBS. If you designed this aircraft with enough wing to support the A/C fully (as a regular airplane does) then the only speed restraint would be that of a regular prop driven fixed wing aircraft. As it increased speed, more work would be taken away from the main rotor. Eventually it would be able to maintain a flat pitch (basically no lift) and RBS would be irrelevant.

PhotoFlyer Posted January 9, 2009 Report Share Posted January 9, 2009 Here is some more information about compound helicopters. It doesn't really talk about RBS, but it's some good information. Also look at the AH-56 Cheyenne. Quote Link to comment Share on other sites More sharing options...
Hella Copter Posted January 13, 2009 Report Share Posted January 13, 2009 It would be cooler if it were coaxial and they ditch the gimpy wing on the side. That wing must make for an inefficient hover. Quote Link to comment Share on other sites More sharing options...
