Contra-Rotating Propeller Driven Aircraft
Aviation | Propulsion
The contra-roating propeller arrangement offers enhanced performance - and has been an aviation fixture for decades.
The contra-rotating propeller arrangement in aircraft utilizes a pair of multi-bladed propeller units ('airscrews') to achieve enhanced performance figures. The arrangement typically sees one unit seated aft of the other and each driving their respective blades in opposing directions, canceling out the inherent effects of torque witnessed when driving just a single propeller unit. A gearbox drives the pair with power supplied from a single (or multiple) engine setup depending on the design. Contra-rotating propellers also have the added benefit of seeing no rotatonal air flow as all of the air is cast through the propeller 'disk' assemblies - producing less energy waste than what is seen in conventional single-screw designs. For these reasons, the arrangement has been a constant fixture in military aircraft developments - both operational and developmental. Modern incarnations exist in the Tu-95/Tu-142 'Bear' strategic long-range bombers deployed by Russia.
