Need Help Researching DH Vampire T.11

Wed Mar 07, 2007 12:15 pm

Hey guys!

I am doing some flight modelling on a DeHavilland Vampire T.11 (two-seat trainer) but unfortunately information on the net on this particular variant is scarce.

Does anyone have detailed informations about this plane? I'm looking for performance figures, dimensions, fuel capacities.. everything! Anything and everything about this plane I could use.

Thanks guys.

Thanks for the reply. I've already used this site. I'm hoping someone perhaps has a book with some information, or technical drawings.. anything?

Aircraft of the Royal Air Force 1918-1958 has some info on the Vampire T.11, including 3-view line drawings. Are you interested? It gives some dimensions and performance that vary a bit from the web page referenced by 2h4.

Powerplant: one 3,500-lb. thrust de Havilland Goblin 35.
Span 38 ft. Length 34 ft. 6 in. Height 6 ft. 2 in. Wing area 262 sq. ft.
Weight: loaded, 11,680 lb.
Performance: Maximum speed, 549 mph at 20,000 ft. Initial climb, 4,500 ft./min. Range 787 miles. Service ceiling 40,000 ft.
Armament: two 20-mm guns plus eight 25-lb. or 60-lb. rockets and two 500-lb. bombs or two 100-gallon external tanks.

Here's the data block on the Vampire T.11 from Aircraft Pocket Reference Library Volume Three: Trainers, from 1964:

Power plant: One 3,500 lb. s.t. de Havilland Goblin 35 turbojet
Max speed, 538 mph at sea level, 549 mph at 20,000 ft.; cruising, 403 mph at 40,000 ft.
Range 853 miles
Initial climb 4,500 ft/min
Weights: empty 7,380 lb; max loaded 12,920 lb.
Span 38 ft. Length 34 ft 5 in Height 6 ft 2 in Wing area 262 sq. ft.
Armament: two 20mm cannon

This source also has a 3-view drawing

Note: It says that of 109 examples built by de Havilland in Australia, 36 were Vampire T.33s with imported Goblin engines (What powered the rest? - Astralian built Goblins, I suppose), 5 were T.34s for the Royal Australian Navy, and 68 were T.35s with increased tankage and non-skid hydraulic brakes.

A couple of more sources:

The Pocket Encyclopaedia of World Aircraft in Colour: Fighters, Attack and Training Aircraft, by Kenneth Munson (1966) has color side view and color split top/bottom view of the Vampire T.55, in the colors of the "Ilmasotakoulu (Air War School) of the Ilmavoimien". (What's that, Finland?) Its data block:
Engine: one 3,500 lb.s.t. de Havilland Goblin 35 turbojet
Span 38 ft 0 in. Length 34 ft. 6.5 in. Height 6 ft. 2 in.
Normal take-off weight 12,920 lb.
Max speed 549 mph at 20,000 ft.
Operational ceiling 40,000 ft.
Range with external tanks 853 miles

It says: The RAF trainer version is the T.11 (its FAA counterpart being the Sea Vampire T.22), while the export version is designated T.55.


Warplanes of the World by J.W.R. Taylor, 1966 has an entry for the Vampire with silhouette of the T.11, and gives the following data for the F.B. Mk. 6:

Power: One 3.350 lb.s.t. de Havilland Goblin 3 turbojet
Span 38 ft 0 in Length 30 ft 9 in
Weight empty 7,283 lb. gross 12,390 lb.
Max speed 548 mph at 30,000 ft
Max range 1,220 miles at 350 mph at 30,000 ft.
Armament four 20mm cannon in nose and up to 2,000 lb of bombs or rockets under wings.

Thanks everyone! This information is all good to use. I also found some pilot notes from the T.11. Those, in addition to this, should be sufficient. I appreciate the contribution to my thread!
