An excuse to look in de Havilland Twin Boom Fighters by B Jones I bought recently;

TG278 had the winds extended to 48ft by the addition of pointed outer wing sections. The Ghost engine was 5" longer and 3" greater in diameter requiring the engine bay to be enlarged. The access doors don't look particularly different to the normal Goblin engined versions. The pressurised cockpit was strengthened by having a metal canopy with circular portholes on each side.

thanks red admiral.
is there any drawing ?

No drawings but four pictures.
#1 is a close up of the rear fuselage with the enlarged engine bay
#2 is from 23/03/48 as TG278 comes in to land after establishing the record
#3 and #4 are pictures of when it was on static display at 1948 SBAC display painted white

Its interesting that the picture of TG278 in flight is different from the one Justo posted. The wings are much higher aspect ratio and have a very pronounced point at the tip. Also, no cannon installation.

I can't give a book review on it yet as I haven't had time to read it since buying it over Christmas.

Hi all
I've three photos of the TG 278. two before modification
(as the one above) and one with the modified wings
This plane is said to be the 5th MK 1 construted by
English Electric and later modified with a Ghost engine.
I have also a photo of the TG 276 with additional air
intakes above the engine bay and no detail.
Has someone an answer. thanks

TG 276 was fitted with a Rolls-Royce Nene engine. The elephant ears behind the cockpit are for extra air to be delivered to the rear side of the compressor.

E.6/41 was the Ministry specification for which de Havilland designed the DH 100 Spider Crab, later renamed the Vampire. This drawing shows a preliminary version of that design and therefore belongs in that thread, it should not have one of its own. How do we get it merged across?

done !
