    The Roton

    I think the main idea was that you wouldnt have to land in the water. Plus if you have the rotors powered by tip jets, then in theory you would have the ability to make a powered landing. All in all it was a fairly interesting idea, which was as much a victim of the iridium failure as much as a...

    The Roton

    Looking for others thoughts on the defunct Roton. The design was definately ambitious, but had they the money would it have worked? (Ignoring that just about anything will work if you continue to throw money at it). What Im particularly interested in is the rotor recovery system. According the...

    Tilt rotor dynamics

    Got about 20 irons in the fire at the moment. :) When you get a chance drop me your new email to my adress. Your not allowed to post email adresses on the forum, got a kick from the mod for that. Drop me a line, so we dont send this to far OT. Christian

    Ceramic Compressor

    Thanx cermax. Is there a type of ceramic which would be suitable for this type of application? Or am I going to have to look at alloys?

    Tilt rotor dynamics

    The Nord 500 used that method with twin ducted fans. Using aerodynamic control of the nacells seemed to be to slow to be effective, however this could have been more to do with the ducts than the control mechanism. Im fairly sure that the V22 uses a hydraulic cross drive, and not a direct shaft...

    Ceramic Compressor

    Im looking at building a compressor for a project Im working on. The problem is that it will see some high temperatures and pressures. I have been doing a little research and from what I have read, Silicon Carbide seems to be a good choice for this, however Ive spent a bit to much time studying...

    Compressor Design Text

    Hey guys, I know cross posting is a little frowned on, but a little help would be really appreciated. Im after a text on compressor design, specifically related to screw and claw types. Info in the area of deriving the shapes of the screw or claw would be a bonus. Thanx in advance, Christian

    Ducted Fan

    I have been looking into ducted fans for either an autogyro or compound helicopter application. I purchased "Ducted Fan Design" by F. Marc Piolenc & George E. Wright. Available here, http://www89.pair.com/techinfo/MassFlow/ductbook.htm Good book, cozy with the ducted fan mentioned earlier in...

    Rotorcraft Heresy and XVTOL

    Your probably right intermesher, just about anythings going to be cheaper than a tilt rotor.

    Intora-firebird. H2O2 helicopter

    elvey, thanks for that. Other than adressing the response theres no real way of targeting anyone. Any pics of the Atlas?

    Intora-firebird. H2O2 helicopter

    Thats a shame. Out of curiosity I read somewhere that it could hover OGE very high (20,000ft), which seemed a little on the high side to me, can you say, if you remember the max OGE figure?

    Intora-firebird. H2O2 helicopter

    Just wondering if they are still working on it. I had heard the military was interested, and the OGE performance seemed phenominal. Can you say the current status?

    VTOL emergency profiles

    Which 22 Mart the osprey or Robinson?

    VTOL emergency profiles

    Im curious as to others opinion on this matter. Mainly should a VTOL aircraft have a VTOL emergency landing configuration? To my knowledge Bell/Augusta have applied to have the Tilt Rotor classified as a powered lift vehile, as opposed to a helicopter. This means they dont have to meet a the...
