RJ Boulton-Paul P.99B Bulwark 3.2

235k RamboJutter  4.3 years ago

Introduction

Specification F.6/42 called for a fighter with a high rate of climb (4,500ft/ min to 20,000ft), good acceleration and good manoeuvrability. Boulton Paul's first design was the P.98, a tail first pusher that was judged to be over-weight. This was followed by the P.101, a staggered biplane with cantilevered wings and the cannon carried within the spats for non-retractable main wheels.

After both of these projects were rejected by the Air Ministry, Boulton Paul submitted two designs with lower project numbers.

The P.99 was a twin boom fighter, powered by a Rolls-Royce Griffon that powered contra rotating pusher propellers. The pilot's cockpit was in the nose, and was covered with a bubble cockpit. In case of emergencies the pilot was to escape downwards, using a system that involved jettisoning part of the lower front fuselage. The armament would have been carried in the nose.

The P.99 was to be armed with either one 47mm cannon, with a 20mm cannon in either side, or two 20mm cannon with a 40mm cannon on either side.

In September 1942 all of the designs submitted to F.6/42 were examined at the RAE, and all of the Boulton Paul designs were dismissed for being too futuristic. However Boulton Paul perservered and produced a prototype of an evolved design, the P.99B which was armed with 4 20mm Aden cannon in the nose, powered by a RR Griffon engine and the originally proposed counter rotating propellors. The RAE re-considered the proposals after testing the prototype and requested a production run of a limited number of aircraft to fit out 1 squadron provisionally.

(Thanks to history of war for some of the speil above)

    Lol no I mean an aircraft like this would realistically not be capable of 4k a min. But it is a fictional airplane so who's to say that it can't! But no lol I didn't mean in game.@RamboJutter

    @NAD thanks, no need to worry about that though, I think that even if I just finish my incomplete builds it will last the rest of the year :)

    @Hedero aw man I never even checked climb rate, I worked on manoeuvrability primarily, it does have a large hp Griffon engine with 2 sets of props so torque / power would have been impressive but if I've over egged it I apologise.

    I am a fan of this design! Absolutely stunning. But how in the crap can this thing climb at that rate a minute?@RamboJutter

    Lol same, I have finished builds some days and I just upload these in 1 day, but I heard it isn’t the best idea@RamboJutter

    @Tang0five you would have to ask Boulton Paul =) i just traced the rear end of the p99 but due to the awkward shape of the fuselage i had to add a tube to connect to the spinner.

    @Diloph lol, i have a folder full of completed builds that i havnt released, so from time to time i just dip into it and put some out there. I also tend to mess around with a load of different ideas and then end up completing a few in one go.
