An aircraft drive system having two propellers, each of which is driven independently by a drive belt which is connected to a separate engine. The engines are mounted in cantilever fashion in a spaced relationship on a hollow sleeve. The sleeve is attached by a pair of spaced brackets to the frame of the aircraft. A shaft is rotatably telescopically mounted within the sleeve by bearings located on the ends of the sleeve. A pulley is fixedly mounted on one end of the shaft and is driven by one of the engines for rotating one of the propellers which is fixed on the other end of the shaft. Another pulley is rotatably mounted by bearings on the sleeve and is driven by a drive belt connected to the second engine. The second propeller is telescopically located about the sleeve adjacent the first propeller and is firmly connected to the second pulley which rotates said second propeller completely independent of the first propeller and in an opposite direction than the first propeller. The sleeve which is attached to the aircraft frame provides the entire support for the two drive engines, pulleys, propellers and associated drive belts.

A drive system for an aircraft including: (a) elongated longitudinally extending support means adapted to be mounted on a frame of an aircraft for operatively supporting all of the components of the drive system thereon, said support means including a fixed outer sleeve and an inner shaft rotatably mounted within said outer sleeve, said outer sleeve and inner shaft each having an extended end; (b) first and second propellers, said first propeller being rotatably mounted on the extended end of the fixed outer sleeve and said second propeller being mounted on the extended end of the shaft in close proximity to said first propeller; (c) first and second engines; (d) bracket means for mounting the first and second engines on the support means; (e) drive means mounted on the support means and operatively connected to each of the engines and respective propellers for drivingly connecting each of the propellers with its respective engine to rotate said propellers in opposite directions with respect to each other; and (f) means for mounting the elongated support means on the frame of an aircraft.
