Anybody got drawings from the Hawker P.1004 project?

[Justo Miranda]

Early in 1940 the Air Ministry issued Specification F.4/40 calling for a two-seat, high-altitude interceptor to counter the threat posed by high flying reconnaissance Junkers Ju 86 P.

To meet this requirement, Hawker proposed the project P.1004, a 25 per cent scaled-up version of the Typhoon with a second crewman, pressurised cockpit and six wing-mounted Hispano cannons.

Early 1941 the Specification was revised as F.7/41 and the P.1004 was dropped in favour of the Westland Welkin.

P.1004 technical data

Power plant: One Napier Sabre Mk 1 S.M, 24 cylinder ‘H’, liquid cooled engine, rated at 1,850 hp, driving one de Havilland three-bladed constant-speed airscrew, wingspan: 52 ft (15.8 m), length: 39 ft (11.9 m), wing surface: 405 sq.ft (37.7 sq.m), estimated maximum weight: 13,930 lbs (6,319 kg) with 283 gal. fuel, estimated maximum speed: 380 mph (611 kph), estimated ceiling: 37,000 ft (12,280 m), rate of climb: 2,250 ft/min, armament: six wing-mounted 20 mm Hispano Mk.II cannons.

Brooklands Museum would be a good start, Chris Farara has amassed a great collection of P.xxxx drawings.

I have attempted a reconstruction of the P.1004 project based on the description of page 47, any opinion will be well received.

Thanks for posting those, makes my day properly when I see craftsmanship like this. Most images are so grainy they wreck my eyesight, these are proper cracking, Sir.

I was just reading about Hurricanes, Henleys, Tornado, Typhoons in Putmans (3rd edition) last night --- Hawker projects P.1001 to P.1003, P.1006 were all associated to the Henley, one being to B.7/40. Another was an escort fighter. Putmans says P.1004 was to F.7/40 so maybe another Henley project.

 

[Justo Miranda]

Henley was a light bomber, I preferred to draw a cockpit similar to the Hotspur, but something shorter because the second crewman was seated with his back to the pilot.

Some of the Henleys were light bombers, but there was a Henley long-range two-seat fighter, P.1003 Henley Escort Fighter then there were two other fighters, P.1007 Single-seat high Altitude Fighter and P.1008 Night Fighter although it doesn't say these two were Henleys. I can't find any other reference to this group of 'P' numbers mentioned above and here though.

Hi Justo:

Could I you ask to create a drawing of the P.1004 in 1/72 scale? I think I can build it in 1/72 starting with the Brengun Typhoon model as the base.

I would need a 6' fuselage inset starting at the end of canopy.
The wing chord taper is good. Need to find/build the 4 1/2' extension.

Attached are photos of the Brengun Typhoon overlaid on your current drawings (98-99% to 1/72 scale).

Any thoughts on the purpose of the 2nd crewman? Note the Welkin only had the pilot.

Thanks

The original is drawn at 1/72, you can print the drawing 123.jpg published here in February 14, 2021 at any size and then multiply 219 by 100 and divide by the wingspan that measures the plane in the copy you have printed. With that you get the percentage of magnification or reduction that you must apply to your printed copy to obtain the same drawing at 1/72. It is a very simple operation that you can do in any photocopy store.
