This is my latest project. It is basically an autogyro time-framed in 1969-1972. Two paired turboshaft engines are coupled to a rear, contra-rotating propeller. Lift are created by the two, counter-rotating intermeshing rotors. Pressure air purged from the compressors can be used to put on rotation the rotors to obtain an early lift and so reduce take-off run. Pilot get forward view (in visible and IR wavelenght) by means of a forward-looking camera pointed through a clear panel. Oblique view is obtained through the oval windows, to control visually the rotor heads. Armament comprised two 20mm cannons and a six-barrelled 12.7mm Gatling gun. A radar allows for target acquisition and rangefinder duties.

I needed two weeks from his inception in hand-draw sketches to the final render.
