Ian L Posted February 9, 2017 Share Posted February 9, 2017 Can you guess what this invention is & the year for double points ? Standard Tilly Helicopter ? Quote Link to comment Share on other sites More sharing options...
Tony B Posted February 9, 2017 Share Posted February 9, 2017 Its an Autogiro type rig, so possibly a test rig? RAF used Autogiros in around 1937/38 for Radar calibration, they were the nearest thing to being able to hover at the time. On closer examination it looks like it's rigged to test lift from the rotor. Quote Link to comment Share on other sites More sharing options...

Richard Farrant Posted February 9, 2017 Share Posted February 9, 2017 The Tilly has Essex trade plate on so I am guessing it belongs to a contractor and not military. In fact it looks a bit rough so I am guessing again that this is postwar. Quote Link to comment Share on other sites More sharing options...
Tony B Posted February 9, 2017 Share Posted February 9, 2017 Then if it is post war, could be a test rig for one of the first Helicopter designs,? Back to the search! But Juan De La Cievra, the inventor of the Autigiro formed a company in England pre war, he was killed in an aircraft accident at Croydon in 1936 though, but one of the men the picture on the left looks similar to him.

Tony B Posted February 9, 2017 Share Posted February 9, 2017 (edited) So Moriarty! :cool2: That as far as British Rotor craft goes is Cievra projects for helicopters or the Saunders Roe Sketter maybe Bristol 171 Sycamore? There is however a jocker in the pack, there was the Jeep Rotatbuggy in 1942 and a rotordrag parachute drop system tested in 1942, so maybe a post war experiment?

ruxy Posted February 9, 2017 Share Posted February 9, 2017 At a certain speed depending on blade inclination setting - the rig will acieve lift , the rear Tilly wheels will loose traction - so it is a runway friction testing machine , bloke tabulating rotor head setting(s) and speedo readings at maximum propulsion.

simon king Posted February 9, 2017 Share Posted February 9, 2017 Post war tetst on the Foker Angelus towed by U Boats? If I remember correctly, The Airborne Forces Experimental Establishment used the original Rotabuggy Jeep for that, still with its ASI and altimeter fitted, but with the tail and rotor removed, towing a platform trailer made from the chassis and base of a 2-wheeled airfield control caravan Quote Link to comment Share on other sites More sharing options...
