Postwar Aircraft Projects / Re: British AST-412 light aircraft
« Last post by ursrius on Today at 11:10:22 am »
AST.412 was eventually fulfilled by the Embraer (Shorts) Tucano. Other competitors on the final shortlist were the Norman Firecracker. Australian Aircraft Consortium (AAC) A.20 Wamira II and the Pilatus PC.9. Flight lists a full list of contenders here: https://www.flightglobal.com/pdfarchive/view/1983/1983%20-%202009.html?search=AST 412

It was a private venture designed as a successor to the company's successful Dragon and using features from their less successful Express

Or maybe un-interested designs for Brabazon Committee,
No, the Committee did not specify any new flying boats, only interim machines from converted Sunderlands

Hi,

can I ask if there was a competition led to develop the De Havilland DH-89 Dragon Rapide
or not?,as I remember,the Westland submitted a rival concept,a twin engined eight seat
monoplane Project ?.

This is a York fitted with a flying boat bottom, and therefore very similar to the 1943 Saro S42 project which was had a new Saro hull fitted with Lancaster wing and tail. Both were speculative designs I suspect, perhaps something shown to the Brabazon Committee in the hope that they may be included in their recommendations

Or maybe un-interested designs for Brabazon Committee,also we cana sk about Avro-686,and
if it was  submitted to a specification or not ?.

Hi,

also we can ask if Avro-685B long-range flying boat transport Project wa just
a private venture or it was submitted to a specification ?.

I expect that HP did the same as Avro and concentrated on submitting a project to P.13/36. If Fairey worked on a project, and I am sure they would have given it some thought as they had for B.1/35 and later B.1/39, it would almost certainly have been something like a development of the Hendon.

Graugrun, I'm trying to figure out if the ATAR upgrade programme is the same as the ATAR Plus.
It seems to me like they weren't..more than one person intimate with the project has mentioned single crystal work done on the blades for the Upgrade. It also seems the Upgrade was worked upon in the late 1980's (?) as an engine option for the Carver, with an increase in thrust seeming to be a vital aspect, whereas the Plus seems to be a couple of years later and doesn't seem to have involved the blades or a thrust increase. It also meant open collaboration with France and Spain.
This is me surmising of course and I could be wrong.
