Looks like the Folland Fo.108.

Good spot. I agree, the undercarriage struts are quite distinctive.

Cheers

Saber VII was similar to V; The main difference was the use of ADI and the strengthening of internal components. Of your 2238 cu.in. Displacement a phenomenal 3500 hp was achieved at 3850 rpm. Finally, Napier tested a Saber at 4000 hp with ADI. No other production aircraft engine has ever equaled those really impressive numbers!

Napier Sabre v-11
From the end of 1942 the English Electric Co
.Grou
p acquired D. Napier
&
Son Ltd, Sir George Nelson
becoming Chairman of the new Board, at which point
Halford
then resigned.
After sleeve valve
seizure problems had been overcome, (this done
after
assistance received via the M.A.P. and courtesy of the more "sleeve" experienced
Bristol Engine Co.), supercharger
enlargement was pursued further, until a
changeover was made to the Hobson
-
RAE injection
carburetor
, which supplied
fuel directly into the supercharger eye, a system taking fuller advantage of the
efficient sleeve valve induction design. The "Sabre
5A" was first to use this
system, but was limited to less than 2600
bhp at 3850 rpm and 15 psi boost, due to
higher power "detonation
". This finally needed also the injection of Water-
Methanol
into an even larger supercharger to suppress the problem (Figure 10),
enabling an unprecedente
d power of 3050 bhp at 3850 rpm using 17 psi boost, to
be produced at sea level for Hawker
fighters on take-
off. The one ton "Sabre"
engine had finally achieved the very low 0.83 lb. per bhp weight
-power ratio in the Sabre 7
version in 1945,
which gave that 490 mph speed in level flight to the
prototype "Fury Mk 1".
Design and development continued after WW2
, with the "E122 Sabre
" variant
intended for civil or service use, this having contra
-rotating propeller
shafts, and 25
P.S.I. of boost from its two
-stage supercharger
, with inter
-stage cooling, to produce
an output of 3350 bhp at 3750 rpm. This project was "nipped
in
-bud" while under
manufacture

Thank Gawd the jet was invented.

This says it is a typhoon with an annular radiator not produced because they wanted more numbers.

Tempest V NV768 ,Annular Radiator test aircraft, this photo is one of at least two variations of the radiator configuration.

Tempest Mark V on completion at the Hawker Aircraft Company works at Langley, Berkshire. This aircraft, JN818, served with No. 3 Squadron RAF and was flown by the Commanding Officer, Squadron Leader K A Wigglesworth, when the Newchurch Tempest wings attacked a V2 launch site in a wood 20 miles north of the Hague on 13 September 1944. Wigglesworth fired on the target, causing an explosion which destroyed his aircraft and killed him.
