I figured with the large international community we have here, it would be a good place to start. Below are three short Youtube videos in Italian. I would like to...

    P-47 Top speed without wing Pylons?

    I was curious of what the top speed of the P-47 would be without wing pylons. I found that the Fw-190 found a 8-10kph increase in speed with the removal of its ETC 504(Which is located under the fuselage. By using common sense, it would only make sense if the P-51 had a better increase of speed...

    What is the real reason the Spitfire 5 had single speed Merlins

    Most descriptions of the rushed production of the Spitfire 5 state that the two speed Merlins could not be accommodated because of their extra length. This is of course rubbish since the ever adaptable Spitfire easily accommodated the very much longer two speed two stage Merlins and even the two...

    Allison P-40 vs Merlin P-40 (or 1 speed vs 2 speed)

    In terms of outright speed, perhaps not. But where the performance was achieved was different. Here are tests of the P-40E and the P-40F http://www.wwiiaircraftperformance.org/P-40/P-40F_41-13601_PHQ-M-19-1440-A.pdf...

    Horton HO 229 Vs Vampire...

    Had WW2 dragged on a year or two longer the the Horton HO 229 and early Vampire jets may have met, I note the Hortons higher cieling and speed, that said, which do you think is best and would have fared better if flown by equal pilots?

    He116 vs. Fw200

    For the naval recon role it seems that there was a better choice than the Fw200, the He116; it had comparable range using much weaker engines; with the same engines the He116 could have performed even better. Was there a reason it wasn't tried? Heinkel He 116 - Wikipedia, the free encyclopedia...

    Do Not Exceed speed later Bf109s

    Someone posted on an internet site the Do Not Exceed speed of the Bf109 was almost always 750km/hr /466mph He also wrote the Bf109 was one of the slower-diving planes of WW2 With Bf109G-10 speed of 428mph or there about Bf109K-4 a tad faster, then some crazy stuff in anti-Mosquito units...

    Optimize the Ju88 for speed

    Question: air intakes

    Hello, Reading a bit about the Bf 109F, it seems that the 109F-4 introduced, after a small number were delivered, the air intake duct of increased size/area. The new duct provided better use of ram effect vs. the old, more restrictive one found in earlier 109Fs. The aircraft top speed was at...

    In-Vulnerable Fortresses?

    How vulnerable were early model B-17s (C-Fs) in the Pacific when flying at 20-30K feet? While they may not be able to hit anything, when flying at top speed at altitude, couldn't they outrun Zeros? If so, they could be useful for reconnaissance and harassment.

    Long wing Fw-190A

    Does there exist a document that describes the flight characteristics in the Fw-190V27 aircraft with the long 12.3m wing instead of the standard 10.5m wing? I would like to know how much the longer wing with increased wing area of 20.3 sq/m vs the standard wing are of 18.3 sq/m affected things...

    P-47 nose

    I am wondering that if anybody put a spinner cone on the nose of a P-47, how fast would the plane fly? And is there a mathematical solution? I am 12 years old and I like to know these things.
