XF-7 Mid-Rear

7,203 Xogo  7.7 years ago

A fictional late WWII experimental aircraft utilising a unique engine layout, mounting two powerful piston prop engines in the mid-rear section of the fuselage, each with a 5 bladed prop and a fuselage-flush spinner. The idea was that the craft could be made incredibly streamlined, while also giving the pilot incredibly good forward visibility, and having a further back CoM. While the prototype was indeed very fast in level flight, climb, and ever maneuvers, the project showed a major flaw on the first test. During a high speed turn, the entire tail of the plane detatched. The propellor design meant that, even with a very thick, hollow prop shaft, the tail had to be atatched through a very thin section of fuselage, which lacked the structural strength for real combat flight. Unable to remedy this, the project was ditched. This is what it could potentially appeard like had it gone into production as a fighter.

    Thanks @Liquidfox
    @szeged6724 The contra prop is just two engines (one inside the other, slightly offset) spinning different ways. You position them with the nudge function (shift and QWEASD)

    How can you make Contra-prop in the fuselage?
