Could shifting the IFF into the pilot's seat correct the balance issues?

Why not take the wings off and mount the P-39 behind the pilot of a P-47? We need novel solutions to this impasse?Could shifting the IFF into the pilot's seat correct the balance issues?
Brilliant!Why not take the wings off and mount the P-39 behind the pilot of a P-47? We need novel solutions to this impasse?
We need to get a solution, this has been going on almost as long as the USA was at war. By 1942 the P-47 was being introduced, whether it had 8 x 0,5mgs 12 of the same or non at all would make very little difference to its tested performance. All fighters got heavier for all sorts of reasons. The Spitfire doubled in weight during the war but was still light compared to a P-51 or P-47, yet still we are discussing the weight of a pilot and an IFFing radio on the P-39. Everything is a trade off and weight didnt matter if it could be coped with and justified. The British used two planes with the Allison engine the P-40 and P-51(as Mustangs and P-51s), both were heavier than the P-39, which they didnt use, because it was rubbish. Much of the discussion is trending to a Reno race with a stipulation that the pilot has a Colt 45 to qualify in the "military" category. An aeroplane with no radio, no armour, and no guns with a crap engine isnt a military machine.Brilliant!
The average American GI was much heavier than that.Average American man in the Army in WWII was 5'8" and weighed 140lbs. Fast food hadn't been invented yet.
The US was still locked in a depression and the majority of recruits were going to eat better than they did in civilian life.re height and weight of US soldiers in WWII, skivies only
The average height/weight of the average US soldier in 1918 was 6'7.5"/154 lbs
The average height/weight of the average US recruit in 1943 was 6'8.1"/152 lbs
Regarding engine cooling, most of the early AAF models (P-38F/G, P-47D, P-51A/B) didn't meet cooling requirements as noted in the Wright Field tests either, just like the P-39. This was common until development of automatic cooling flaps in 1944. P-39 never got these.
Apparently the P-39C had semi automatic cooling flaps. At high speed the airflow pushed them shut.
There is also a difference between a plane that has trouble cooling in a long hard climb and one that overheats in high speed level flight.
No auto cooling flaps. Spring loaded, airstream pushed them back partly closed.
Most important, the P-40 was already in service with few problems with the RAF in N Africa before a P-39 was unpacked in UK, by the time the P-39 was sorted the P-40 was also sorted and being used increasingly as a fighter bomber.Well, on paper, the P-39 is faster, has a better climb rate, and a heavier offensive battery than a P-40.
But, the P-40 rolled better, held a turn better, and could take more punishment. Plus it could carry more external armament. And had better range. And was easier to service. There is a reason that P-39 equipped units in the field clamored for better aircraft. By the time better P-39s became available, P38s, P-47s, and P-51s were being produced in quantity. As to the USSR, the P-39 was the best on hand when it was introduced there. It was faster and more maneuverable, and had better pilot visibility, radios, etc., than the early LaGGs, MiGs, and even Yaks, and head and shoulders above the I-153s and I-16s the Russian pilots had been flying.
As one who stands about two turds and a half above ground fully stretched, I strongly protest against this recent fixation on height, first disguised as ceiling of aircraft but now blatantly heightist and clearly demeaning of us who are vertically challenged.re height and weight of US soldiers in WWII, skivies only

In my working life there were more jobs that required small people than tall ones. Eric Brown thought that he survived the Dh 108 going into rapid oscillation because he was small, it broke Geoffrey de Havilland's neck doing the same.As one who stands about two turds and a half above ground fully stretched, I strongly protest against this recent fixation on height, first disguised as ceiling of aircraft but now blatantly heightist and clearly demeaning of us who are vertically challenged.
Anybody sharing in my experience of being relegated a status as below average, is recommended to join us in the movement for equal heights.

P-47 didn't see combat until April 1943. I doubt the Spitfire doubled in weight but horsepower roughly doubled also. Weight did matter when the engine only developed 1150hp. Tell the Soviets that the P-39 was rubbish. And it had a radio, and armor plate/glass, and large caliber guns, and the engine wasn't crap. It was definitely a military machine. As long as you keep saying obviously false statements like this I will keep disagreeing with you.We need to get a solution, this has been going on almost as long as the USA was at war.

Instead of pondering and doubting why not look something up. Everything you say the P-39 had you want to take off, armour guns radios the lot. Thats why I havnt a clue what your point is.P-47 didn't see combat until April 1943. I doubt the Spitfire doubled in weight but horsepower roughly doubled also. Weight did matter when the engine only developed 1150hp. Tell the Soviets that the P-39 was rubbish. And it had a radio, and armor plate/glass, and large caliber guns, and the engine wasn't crap.
