    Secrets of the D-30F6 Turbofan

    I've always wondered about how the Perm D-30F6 turbofan is able to power the MiG-31 to Mach 2.83, when it appeared to be a relatively conventional adaptation of the D-30 commercial turbofan family. Source is ENGINES OF RUSSIAN COMBAT AIRCRAFT by Kotelnikov V. R., Khrobystova O. V., Zrelov V...

    new big 'Ogre' tank that combines functions of tank and self-propelled howitzer?

    Like those of most countries, US Army tanks have relentlessly increased in weight since the M4 Sherman in World War 2. As you have heard, for decades now voices have advocated entirely replacing the M1 Abrams with a much smaller, lighter tank, even a wheeled vehicle. The lighter tank would have...

    Flashpoint - Cold War gone hot, 1948

    Just came across Operation Downfall, and was pondering. What might be the political situation that would warrant the plan coming to fruition? What projects would be pursued and put into production, and what wouldn't? Who would win the war? Perhaps the 3rd world war would be caused by a...

    MiG 19 -> Soviet F-5 -> Soviet F-20?

    Lets send the MiG company on the path not chosen wrt. their 'budget' fighters. Instead, they make a spin-off of the MiG 19 that has a wing better suited for high speeds (not 8.74% t-t-c at root as on the -19, but under 4.5% as it was case with MiG-21; wing is also of the shorter span), and...
