We know very well CW company

During my training as a teacher, I was once advised to never consider something as self-evident. I have noticed you often start your threads by such phrases as "we know very well", but isn't it better to consider there might be some on the forum who don't, and who would be glad to? But if you say "we all know" they may feel like idiots and so they don't dare to ask!

This time around I will take the risk of sounding like a complete ignorant: I DON'T know the C.W. company at all! To me, these initials are short for Curtiss-Wright, which this aircraft obviously isn't. So please tell me more if you will, hesham...

C.W Aircraft Limited was not a well known company, formed around 1935/36 at Slough, buckinghamshire, in England, by C.R.Chronander and J.L.Waddington, for the purpose of designing and building a 2 seat all metal light aircraft. The aircraft known as the C.W Cygnet, ( G-AEMA) first flew around May 1937 powered by a 90 h.p Cirrus Minor. Development work and flying continued up until March 1938, when as no orders had been forthcoming and large sums had been spent on the C.W Swan project, the company foundered. The Cygnet design was sold to General Aircraft Limited, who after modification built a batch of ten under the G.A.L.42 Cygnet II designation, and a futher one-off development known as the G.A.L 45 Owlet trainer.

Another version of the Swan from "Flight" magazine. Twin-Cygnet would be a better name.

Nice find, certainly a different proposition to the later design. and would have possibly cost a lot less to develop. Engine choice is interesting.

From "British Piston Aero-Engines And Their Aircraft - Alec Lumsden"

Villiers 4-L-318 Maya I, 130h.p. (1936) 4-cylinder, inverted in-line air-cooled poppet-valve engine. It was unsupercharged and its propeller was direct, tractor-drive. It featured ' radial ' cylinder heads, with widely played valves for efficient cooling. As a result of carefully balanced design, the Maya was notable for its smooth running. The onset of war in 1939 prevented the production of a more powerful MkII version. Bore/Stroke 5.5:1, later raised to 6:1, when maximum power increased from 130 to 135 h.p. Direct R.H tractor-drive. Length 43.88 in, width 15.75 in, height 22.75 in. Flight tested in Miles M.11B Whitney Straight G-AERC.

Regards Bailey.

I think that's all aircraft designed by this company,right ?.

Yes. Having sold its aircraft designs and manufacturing rights to General Aircraft, C-W Aircraft became the Chronander Waddington Aircraft Ltd in 1938. The new company shifted its focus to providing tooling, etc. to aircraft makers. They lasted until 1949.

I notice that Wiki credits Chronander and Waddington as designers. No mention of J. A. Heron as chief engineer. According to The Aeroplane, Heron was with Hiduminium Engineering, Ltd. until its parent firm - High Duty Alloys, Ltd. - closed Hiduminium in 1943.

And the Swan was the design work of Roger Dickson, ex-Supermarine, Cloudcraft and Saro. After CW sold their projects to GAL Dickson went with them where he worked on the GAL40 & Owlet [edit: - sorry, that should say GAL33 Cagnet] before rejoining Supermarine on the outbreak of war and then emigrating to the US in 1952
