Bristol Type 147 & 148

[hesham]

Hi,


the Bristol Type 147 was a day and night turret fighter project,powered by
one Pegasus engine,intended for F9/35 Specification.


The Bristol Type 148 was a two seat army co-operation low-wing monoplane,
actually built,and had two anther variants; Type 148A and Type 148B.

The type 147 was intended to carry, what seems to me a very advanced turret :
From C.H.Barnes "Bristol Aircraft since 1910 " : "..., but the gunner had a rotating
seat with remote controls for operating a flush-fitting four-gun dorsal turret. The
movement of the guns through 90 degrees in elevation and 180 degrees in azimuth
was copied mechanically from movement of the gunner's reflector sight which he
controlled by two handwheels."
Was this turret actually fully developed ? Cannor remember seeing it on another type.

New Info my dear Jemiba,thank you.

Supermarine planned a similar turret system on the Type 305, also to spec F.9/35

Indeed, in Tony Buttlers BSP 1935 - 1950, there's a drawing showing the field of fire. It seems, the guns couldn't
be depressed to fire directly abreast (level with the wings) , as can be assumed by the drawing of the type 147, too.
That could be regarded as a tactical disadvantage, I think !

Hi

Leslie Frise and Bristol took out 10 or more patents relating to gun turret designs between 1935 and 1939 It was certainly something they spent a lot of time and effort designing although I don't know how many types were actaully built and tested
