Nice to have you here - I don't suppose you have any interesting tales to tell?Mascaret said:Interesting thread. I was Head of Future Projects at Westland from 1980 until ~1991. I think that the first project report that I wrote (1975) was on the Supersonic Rotor Helicopter study...
Can you tell us any more about Westland's compound concepts for the EH101 and Lynx?Mascaret said:I did lots of work on advanced compound helicopters, plus UK attack helicopter studies (which were allocated WG numbers) and was on the configuration team for NH90 (Feasibility & pre-definition study) and the A129LAH project. Commercial and security considerations mean that it is not appropriate to put additional information in the public domain.
In the Gyrodyne the last- mentioned (collective) is replaced by a throttle lever
Does the 'handle' operate the throttle at low ranges and then the collective at higher ranges of movement?As the throttle is opened, the rotor gathers speed, and when the right revs have been attained, a further movement of the throttle lever increases the pitch collectively and the machine takes off.
This automatic action is achieved by having the blade hinges sloped in such a way that, as more power is applied, the combined movement about flapping and drag hinges gives the desired pitch increase.
An interesting co-axial. Does anyone know if there is anything other than a spiffy model on this particular effort? Although without some serious rotor rigidity I am not sure I would want to fly the bugger.fightingirish said:Westland high speed helicopter concept.

I'll second the request for additional information about supersonic rotors.Basil said:Thanks, circle-5. It would be really interesting to get additional information about these supersonic rotors.
I sent a PM to SPF member Mascaret, who wrote the 1975 report on supersonic rotor helicopter research for Westland Helicopters.yasotay said:
There should be a law against leaving the forum without authorization...PaulMM (Overscan) said:Masceret hasn't been active on the forum since 2010 and his email no longer works unfortunately.
I'm pretty sure we have a post or two on this one already... These pics are from the Putnam book.circle-5 said:From the same Photobucket album, a 3-engine variant of the 1973 Westland SSRH, with 3-bladed rotors:
