most if not all the surviveing models of Airspeeds projects can be found at the Mosquito museam at Hatfield house. They are displayed in the same hanger as the mossi prototype, the AS 69 MPA is there but i dont recall the turbo Ambassador

Hi ! First I introduce to You. I'm Polish and I'm sorry for my Polish - English language
as I used to learn English million years ago just from the Beatles songs and recently I practiced it
mostly in Luton, London and Cardiff pubs, but I hope that You'll understand what I mean.
English and Welsh pub mates did :)
While trying to post here I noticed the warning : " This topic has not been posted in for at least 360 days.
Unless you're sure you want to reply, please consider starting a new topic.
",
but I thought to myself, that there would be much better to refresh still existing thread
than to make a new topic, all the more so as I wanted in my post to treat the flightglobal list
enclosed by hesham. By the way thanx to him :) 'cause it helped me to complete
my own military aircraft designations register.
Unfortunately I never interested in Dutch aviation, having my time only for US, British, Australian,
German, Japanese, Soviet and Polish military airplanes, so now I have no idea
how the Fokker's fighters D.XIX as AS.19 ans D.XX as AS.21 looked like.
I would be very grateful for any information about those planes, the best for the links to photos
as in my registers every aircraft has a shortened description indicating configuration and role,
for example :
A.S.30 Queen Wasp 1II–W Tn. 33
...
33 D. Mondey : British Aircraft of World War II, s. 12.

Next question is if the Airspeed Powered Horsa, prototype of famous transport glider
with two Armstrong Siddeley Cheetah 275 kW engines, has a separate designation ?

harrier said:
Does anyone know anything about the Airspeed AS.49 (I don't have the Putnam)?

Here's the A.S.49:

Designed to meet Air Ministry specification T.24/40 for an intermediate single-seat fighter trainer, the AS.49 was a low-wing aircraft with fixed cantilever undercarriage and, in one form, a supercharged 295 hp de Havilland Gipsy Six IIIS (the RAF Gipsy Queen 51) with constant-speed propeller. Another version had a 250 hp Gipsy Six IV (the RAF Gipsy
Queen 31). For simplicity, cheapness and the conservation of other materials, it was to be built largely of wood with a two-spar ply-covered wing in three sections and a ply-covered fuselage.
Progress on this design had gone quite a long way when, as recorded in the company history, bombs on Hatfield (where the Airspeed design team were then working) from a raiding Ju 88 destroyed the mock-up and caused a fire which burned the design calculations and drawings.

Span 25 ft (7,6 m); overall length 22 ft 7 in (6,87 m); wing area 98 sq ft (9.1 sq m).

AS.49 (Gipsy Six IIIS). Loaded weight 2,540 lb (1,152 kg). Maximum speed at 8,000 ft (2,438 m) 228 mph (367 km/h); maximum economical cruising .speed at 8,000 ft (2,438 m)
202 mph (325 km/h); rate of climb, sea-level, J,940 ft/mIn (9-8 m/sec). Range at economical cruising speed at 8,000 ft (2,438 m) 390 miles (628 km) excluding 30 min climb.

AS.49 (Gipsy Six IV). Loaded weight 2,350 lb (1 ,066 kg). Maximum speed at sea-level 196 mph (315 km/h); maximum economical cruising speed at 6,000 ft (1,830 m) 177 mph
(285 km/h); rate of climb at sea-level 1,250 ft/min (6.3 m/sec). Range at economical cruising speed at 6,000 ft (1,830 m) 360 miles (580 km) excluding 30 min climb.

Thanks a lot Stargazer! The link I posted omitted the crucial word 'trainer'! I was thinking it was perhaps some sort of emergency fighter with a tiny engine!

Dear colleagues, hasn't somebody a list of year-by-year production of AS.10 Oxford? It's well known that 8586 aircraft were produced, but I never seen the distribution year-by-year. Please, help.

I've gathered up the AS designations in plain text to make them 'search engine friendly'. A few details, corrections, and links have been added but there are still descriptive 'holes'. Other than two designation numbers which were apparently not used - 13 and 25 - there are a number of entries which are quite sketchy, (As always, further additions and/or corrections are most welcome.)

Directly below are listed those Airspeed projects for which no AS designations are known. It is just possible that the powered Horsa and General Coastal Reconnaissance Envoy concepts received sub-type designations. That's less likely for the flying boat jet fighter and highly improbable for the Sabre-powered fighters. I've also included the Airspeed-built Shackleton-Murray SM.1 light plane prototype - mainly because it seems to have acquired an Airspeed construction number.

Can anyone add further details to any of the Airspeed AS designations?

__________________________


Undesignated Airspeed Aircraft Designs

Recce Envoy
: It is often claimed that Air Ministry Specification 18/35 had been written around the winning Avro 652A proposal (which became the Anson). However, that story may be apocryphal since Airspeed also submitted an unsuccessful bid to Specification 18/35. This was in the form of a General Coastal Reconnaissance variant of the AS.6 Envoy.

Sabre Fighters: In 1940, Arthur Hagg designs for Napier Sabre-powered fighters constructed mainly from non-strategic materials (one with straight wing and retractable undercarriage; one with cranked wing and fixed, spatted main gear). Some similarities to Hagg's Napier-Heston Racer design.
-- https://www.secretprojects.co.uk/threads/airspeed-napier-sabre-fighters-june-1940.27685/

Flying Boat Jet Fighter: Airspeed sketched out a flying boat jet fighter for airfield-free use in the Pacific Theatre. This blended-hull fighter was closely based upon the AS.37 flying target. However, the cockpit-top-mounted piston engine was replaced by a forward-placed centrifugal-flow turbojet engine with bifurcated jetpipes. Proposed armament was four 4.5 inch recoilless guns.
-- https://www.secretprojects.co.uk/threads/airspeed-flying-boat-jet-fighter.3460

Horsa Powered-Glider: Listed under AS.52 is a proposed self-recovering, powered Horsa variant which seems to have no designation. This aircraft was to have twin radial engines of modest output - either Armstrong Siddeley Cheetahs or Pratt & Whitney Wasp. Neither engine type would have sufficient power to turn the Horsa into a transport aircraft. But, there would be enough power for empty gliders to be flown out of their landing fields.

Piece Work - The Experimental Shackleton-Murray SM.1 Light Aircraft

William Stancliffe Shackleton began with Bleriot/ANEC before becoming Chief Designer for Beardmore in 1924. His health took Shackleton to Australia where he became Chief Engineer at LASCO. When LASCO failed, WS Shackleton returned to the UK and joined forces with Australian Pilot, Lee Cameron Lathrop Murray. In 1931, the pair formed Forward View Aeroplanes, Ltd. and designed an ideal light aircraft, the Shackleton-Murray S.M.1. In Sept 1932, a contract was signed with Airspeed Ltd. to build the prototype S.M.1.

Construction work on the 2-seat SM.1 was begun in Airspeed's rented premises in York but completed after the firm's move to Portsmouth. The protoype SM.1 - Airspeed c/n 8 - was completed in 1933. For completeness, basic SM.1 details are given below:

SM.1: 1933 2-seat, dual control light plane, x 1
- SM.1: Open tandem-seat parasol pusher prop
- SM.1: Mainly fabric-covered wooden structure*
-- * W/ welded/pinned steel-tube centre section
-- * Wings capped with papier-maché wing tips
- SM.1: 1 x 70 hp Hirth H.M.60,** span 12.20 m
