I'm okay with speed of the Merlin 'Gloster' to be half way between the Hurricane I and Spitfire I - 340 mph - even thought the early P-40 was faster still (with the fully rated V-1710). Puts it in the ballpark with the Bf 109E instead of the 35+- mph deficit the Hurricane had; it is also a tad faster than the Bf 110, unlike what Hurricane was able to do.
It should also dive and roll better than the Hurricane (ie. at least as good as the Bf 110), and not require a new wing to be constructed in order to rectify the weak points of the old wing.
The idea behind showing the weights was that both alternatives would wind up heavier than the Hurricane after the engine swaps. The Bristol could windup over 500lbs heavier (crediting the Bristol with over 100lbs for it's propeller).I accept the weight gain, just like the actual companies did in order to make better performing fighter.
Defending the installation of a Merlin on a British fighter is a completely new experience to me, to be frank. BTW - what happened to the often stated information of the (X)P-40 being 22% less draggy than the P-36
We have to believe that a smaller wing (by 30sq ft) Bristol that is 2-300lbs heavier than the 'equivalent' Hurricane is actually cheaper to build.
Wiki seems to be wrong (and may be in conflict with itself) and first flight of the unarmed prototype was in Dec of 1937. Armed 2nd prototype was flown in March of 1938 at which time the Hurricane has been issued to the first squadron and two more were equipped by the end of June 1938.
Chances of hitting 340mph with the existing landing gear????
I have serious doubts about the F.5/34 hitting the claimed speed as so much about it seems wrong. That or everybody (every British and American aircraft company) should have been given an F.5/34 for study.
the P-36B with a modified R-1830 engine giving 950hp at 17,000ft was only able to hit 317.5 mph compared to claimed 316mph at 16,000ft for the F.5/34 with 840hp.
Or compare to the MC.200 that did 313mph at 14,800ft on 840hp, granted the MC.200 engine cowl/fuselage was a bit of a clown show but the wing was 50 sq ft smaller than the F.5/34 and had fully retractable landing gear instead of semi/retractable.
Find another radial engine fighter with so little power with such obvious drag producing features that went that fast.
Ki-43 and A6M2 were similar in size, wing area, weight and had about 100 more HP, the Ki-43 was slower and A6M2 was faster.
If the F.5/34 truly was that fast the British lost the recipe for "Gofast paint" and/or "anti-gravity" paint.
Also needs a new tailGranted, MB.2 needs to be designed with the Merlin in the nose from the get go, if it is to be accepted into production in a timely manner.
This was the modified tail after the first/s flights
Now ask the Air Ministry to risk an Merlin engine in that thing with the vertical stabilizer cut down to the top of the fuselage?
It took the designers at least one more try after the photo and maybe two give up on the idea of using using the rear fuselage side area for stabilization.
