The Hercules got a substantial redesign in the 200 series. This included new main bearings with larger diameter rollers in the rolling bearings, Only the new power section was rated at 2000hp or close to it. It was an amazing achievement but effective use was post-war. 1938-39 Bristol was having...

Perseus = 24.9 liter engine Taurus = 25.4 liter engine we are depending an awful lot on higher rpm and the advantages of small cylinders for a significant increase in power. R-1830 = 30.0 liter engine for comparison.

Main thing is to throw the cylinders and heads out and start over. There were a couple of prototype engines used the Gloster twin that disappeared after the crash and never came back again. The Service engines had a lot of trouble overheating and if the engines are overheating at 3000ft trying...

Hoping this is joke, reported by the Onion?

First flight of the prototype was 27 May 1955. First service flight was April 1959. The Caravelle was innovative and did a lot of things right. Jets got to be very reliable in the 1950s but it took 7-10 years from 1945 to really start fulfilling the promise. Granted with a limited design...

Yes and no. Military was very focused on jet propulsion. Civilian aviation.........not so much, at least in the 1940s and early 50s. The promise for civilian aviation was there. Actual delivery kept getting put off. Jets could use cheap fuel (although some 1944-47 jets used gasoline) but they...

True but the Pz-IVH didn't start production until April of 1943 (?). The Pz-IVG started in production in May 1942 with the slightly less powerful L/43 gun. The L/48 didn't show up until March 1943. A number of Gs got heavier armor, 30mm on top of the normal 50mm. But this was roughly 1/2 of...

Post war the French also had production facilities that could build Jumo 213 engines and facilities that could make BMW 801s (or a large part of the components that made up BMW 801's). Problem was selling them. Nobody, except the US, had money for new planes (or at least more than handfuls) and...

Thank you. Point I am trying to make is that the equivalent of the KwK 40 or 77mm HV doesn't really do anything for the Soviet artillery (Field or AT) in 1941 or 1942 or even for much of 1943. Difference in shell weight in minimal. Difference in max range, unless you provide for the same or...

Revisiting this Maybe not but for some of those years does it really give the Soviets any real advantage? And in 1943/44 are higher powered 76.2mm guns offer any advantage over the historic 85mm guns? Advantages of higher powered (higher velocity) 76.2mm guns are. 1. more armor penetration...

Aside from the first P-40Ns there wasn't more than 300-500lbs you could easily take out. About 130lbs for two guns About 140lbs (?) give or take for the ammo. about 150lbs for difference in fuel between 120 gal and full tanks. While the factories did pull the forward tanks and squadrons did...

I am not sure if the British ever got any French fighters to test in England or maybe they did some tests at French airfields to see if a more extensive test was warranted. There may be French tests in French language literature.

There is a manual for the P-40D&E. on this web site. https://ww2aircraft.net/forum/threads/p-40-flight-manual.7478/ Post #2 The manual starts with the empty weight (with radio) of 5894lbs which is 220lbs(?) heavier than the P-40C. P-40E is about 90lbs heavier but this is without guns/ammo and...

Vokes filters seemed to be a double wammy. A lot of external drag and reduced RAM effect (or even hurting intake pressure at low speeds). Most of the American air filter systems didn't seem to hurt things as much although some of the bomber intakes look like they were high drag. But then a...

and the War Office said we didn't need float planes !
