I haven't actually decided on a colour scheme but, I rather fancied one as a captured example in RAF prototype markings - with the yellow undersides!! Assuming any RAF test pilot was going to be brave (mad?) enough to fly this contraption! I think even the late, great Eric "Winkle" Brown might have shaken his head sadly and walked away from this one!!

Rui Silva Posted August 6, 2018 Share Posted August 6, 2018 (edited) Hi all, Just saw this, the Hiller HJ-1 / YH-32 (US Army) / XHOE-1 (US Navy) Hornet family of helicopters powered by tip ramjets sucessfully flew without need for a tail rotor. Noisy as hell and fuel consumption was horrendous... I wonder where can I get the Triebflügel kit when it's released?

Rui Silva Posted August 6, 2018 Share Posted August 6, 2018 Hi all, What I said above about the Hiller HJ-1 "Hornet" and the YH-32 / XHOE-1 is not entirely accurate, I was mislead by Wikipedia (https://en.wikipedia.org/wiki/Hiller_YH-32_Hornet) that states: "The HJ-1 ramjet tipped rotor propels the rotor and the aircraft. Unlike a conventional helicopter, this mechanically simple design avoids the need for a tail rotor" This was true about the civil HJ-1, which had no tail rotor (it used a conventional rudder) but not so true about the military versions, these had a small single-bladed tail rotor to improve yaw control, hence the yellow tail rotor warning stripe in the photo I posted. An interesting page about the Hiller "Hornet" and all its problems: http://www.aviastar.org/helicopters_eng/hiller_hoe-1.php Rui Link to comment Share on other sites More sharing options...
VMA131Marine Posted August 6, 2018 Share Posted August 6, 2018 On 8/2/2018 at 7:03 AM, Denford said: There is indeed no torque between the fuselage and prop, but this wouldn't stop the former from rotating. I've seen this at first hand. Not true! Torque is transmitted through bearing friction from the prop to the fuselage. Presumably the tail surfaces, which would have to control roll as well as pitch and yaw, would be used to counteract it. On 8/2/2018 at 7:03 AM, Denford said: Another (so far) unmentioned feature of the Triebflügel would be the large gyroscopic effect of the motors, The gyroscopic effect would act to keep the axis of the fuselage pointed in one direction. Application of forces on the tail to pitch or yaw the aircraft would have to be at 90 degrees to the intended direction of motion due to the gyroscopic effect, which is also present on helicopter rotor blades. On 8/2/2018 at 7:03 AM, Denford said: I've overlooked too what might happen if any engine 'faltered' or gave a different thrust (for any reason) from the others. I don't think this would cause a problem. The biggest issue would be if something fell off one of the rotor blades causing the rotor to become unbalanced. 3 Link to comment Share on other sites More sharing options...
Harold55 Posted August 7, 2018 Share Posted August 7, 2018 As long as I this is going to be a what if you have quite the scope of how you paint it. Yes RLM is going to be more common but I would love to do mine as Italian or as Soviet (they used them in the Korean War). 2 Link to comment Share on other sites More sharing options...
Martian Posted March 25, 2019 Share Posted March 25, 2019 No surprises for guessing that I am up for this one big time!

general melchett Posted May 6, 2019 Share Posted May 6, 2019 Yes, another contraption I rather fancy the look of. Here's a (poor) shot of the 1/72nd Huma kit I built many, many moons ago, (before the invention of the airbrush evidently) and remember enjoying it. I seem to recall having most of the wonderfully esoteric Huma kits at the time. Of course it's ridiculous but then that's the fun of it. If the thing had ever managed to get itself into the air then the noise would definitely have been an issue, not only for the general populace but also the suicidally inclined pilot who may well have succumbed to the nauseating effects of having three ramjets swirling around him at a fair rate of knots, (never mind the effects of acoustic fatigue on the rest of the airframe). You would have heard this thing coming over a considerable distance...I hate to think what may have happened had one of the ramjets been slightly out of sync with its neighbours on lift-off/landing. + 4 Link to comment Share on other sites More sharing options...

SleeperService Posted May 11, 2019 Share Posted May 11, 2019 Hello my green tentacled extra-terrestial How are you doing? I think it would need a rather large dose of National socialist Ardour to get anywhere near this. Melchie's Japan suggestion is pretty good.

I think this thing would have flown alright but without some sort of computer stabilization for landing, which was not available in 1945, it would proved very difficult to land as did most of the other tail sitting designs of the post war period and ended up in the too difficult tray alongside them. It was however, a serious project and had reached the stage of wind tunnel testing of models when the war ended. Will any of this stop me from coming up with a barking mad build? Not a bit of it!

This I very much doubt Martian, even Gag Halfront has reimbursed me and gone into therapy...It looks rather like Catpain Amurica (and Fantastic Plastic) pinched the idea some time ago but with a slight modification, and I think they had the right idea...get over/somewhere relatively near the target, open the canopy ...and jump out...seems by far and away the safest option. Quote I think this thing would have flown alright Wow, now that's what I like to hear....that is the kind of relentless optimism against all the odds that made us Brits the Guava nicking Empire we became...Hoorah.

Work In Progress Posted May 12, 2019 Share Posted May 12, 2019 I am sure it could have been taken off and flown around. Equally sure that it could not reliably have been landed safely in anything other than ideal test circumstances of weather (zero wind a must), a level firm and well-drained surface, good daylight and suitable surroundings providing some peripheral vision cues. Even with auto-stabilisation which could potentially have made the landing a matter of instructing the autopilot rather than direct manual handling, it's hard to see how the basic design allows for it to be landed level on the tail in any kind of wind. With those little tiny wheels if it landed with any drift on it would be prone to trip and fall. So to get zero groundspeed in the wind It would have to lean, right up to the point of touchdown, thus introducing other significantly topply possibilities. I quite like it as an airship-hangared device which could be flown nose-first into some sort of suitably angled receiver socket. Anyway, gloriously loopy and I can't wait to get mine. 1 Link to comment Share on other sites More sharing options...

general melchett Posted May 13, 2019 Share Posted May 13, 2019 Now, if Elon Musk would hurry up and develop a trans-dimensional warp drive and pop back with his SpaceX team to 1946 I'm sure he could sort out a few of the shortcomings of the design. I hope this will be followed up with more wonderfully insane ideas from the period...how about an IM 1/48th Heinkel Lerch II?
