Hi,

on the site " Forked Ghosts ", I´ve found a pic from the P.36. There also speak about the mostly like projects P.35 and P.37.
Any pics, drawings or technical data?

Provisional data : from The Aeroplane , February 18, 1944

High-wing monoplane.
Span:158 ft.
Lenght :103ft
Weight all-up:150.000lb
Six or four engines of 2.500hp each (type not specified)
Max range with 150.000lb - 1.650 miles
Top speed :328 mph
Cruising speed at 50% of max.power:316mph
 
error: cruising speed must be 216mph... sorry.
 
BSP: Fighters & Bombers 1935-1950 mentions the Percival P.26 project for an engine testbed dated 1938.
No other fighter or bomber designs are noted, did they design anything else during the war? Or is it a case of lost archives?

but also communications and training aircraft, not to be despised. (Proctor etc)

I seem to remember a proposal to fit Percival Mew Gull racers with a couple of machine guns as a stopgap emergency fighter, I have no references though.
 
A.A. Bage,the Percival chief designer prepared a project for adapting
the existing 205 h.p. Gipsy Six Series II powered Mew Gulls for anti-invasion
ground-attack defence.
Designated P.32AA, the superb little racers were to be armed each with a pair
of .303 Vickers machine guns at a loaded weihgt of 2,400lb ,with which
a top speed of 210 m.p.h. was expected.

from : The British Fighter since 1912- Peter Lewis- Putnam/London 1967.

Now , we only have to find an artist impression or G.A drawing...

In John Silvester's book ('Percival & Hunting Aircraft') there are three photographs of a model of the four engined version of what is, it appears, the P.36 project. It also mentions that there was an article on this project in the February 1943 (?) issue of The Aeroplane.
 
Please see : Percival P.35 to P.37 bomber/transport projects..
 
A bit more about the P.32...

Span: 25ft
Lenght: 21.7ft
Gross weight:2400lb
Max Speed 210 mph
Tot. Hp :205

found in : The Aeroplane Spotter Febr7 1948.

As can be seen, the dimensions are close to the MewGull Mk II and MkIIA of 1935 and 1938.
 
Hi,


here is the Percival P.8 for Spec. 32/35.

Quick question, what is/who makes a Bombardier engine and what configuration is it? My only knowledge of the name is Bombardier the airframe manufacturer of too recent vintage to have built a powerplant for a Percival design.

The Bombardier was designed and built by Blackburn, it was a 4-cylinder inverted inline engine, a post-war replacement for the Cirrus. Was used in the Auster AOP.9 and one was trialled in a Saro Skeeter. Never seems to have been particularly successful.
There was also a planned engine - the Grenadier - which stayed on the drawing board.
 
Ah, thank you, Hood. Based on the original Blackburn Cirrus Minor, which was originally derived from Frank Halford's Airdisco Cirrus, half a war surplus Renault V8 and the invention of the inverted four that became so popular between the wars.
 
There were two variants of the Bombardier - the Mk. 203 (used in the Auster AOP.9 and B.4) and the Mk. 702 (used in the Cierva W.14 Skeeter IIIB (prototype) and V, Auster B.4 and Miles Messenger V (Source: 'British Piston Aero-engines & their Aircraft', Alec Lumsden (Airlife, 1994)).
 
By the time of the Munich Crisis, it was unclear to the British authorities if the production of the new monoplane Hawker Hurricane and Supermarine Spitfire fighters could be accelerated sufficiently to equip the 123 Squadrons that the Fighter Command required for the defence of the British Islands.

During the critical days of 1940 the 'Panic Effect' boosted numerous interim solutions to increase the number of fighters available: A.A. Bage, the Percival chief designer, proposed to build a version of the Mew Gull armed with two 0.303 in Vickers Mk.II machine guns. The projected light fighter, called Percival P.32 AA, would have 7.62 m wingspan, 6.57 m overall length and 1,087 kg maximum weight. But it was rejected in favour of the Miles M.24, the single-seat version of the Miles Master.

The projected fighter Percival P.33 AB, based on the aerodynamic configuration of the Mew Gull racer that competed for the Merlin XX engine, was also cancelled. It would have been a 556 km/h fighter armed with four Browning, with 12.24 m wingspan, 9.2 m overall length and 2,848 kg maximum weight.
