Designed to meet and tested to exceed ASTM F2506 (Standard Specification for Design and Testing of Light Sport Aircraft Propellers), AXSport Aviation’s range of lightweight three-blade electric constant speed propellers are designed for non type certified aircraft using the popular Jabiru 3300, Rotax 912/914 and Lycoming O-235/320 series engines.
We often hear “Constant speed propellers are great, but they’re too complex, heavy and expensive for my aircraft.” That’s no longer the case with our range of constant speed propellers. The AXSport propellers are simple to operate and weigh little more than ground adjustable propellers.
Ground adjustable, and even more so, fixed pitch propellers, are a huge compromise. The propeller pitch is optimised for one operating point (speed and RPM) only. This could be for climb, cruise or in between. At all other operating points the engine will not be producing full power. This is not the case with a variable pitch propeller. The constant speed propeller is the ultimate refinement of the variable pitch propeller, as the microprocessor controller automatically adjusts the blade pitch in order to maintain a chosen RPM, irrespective of the amount of engine torque being produced or the airspeed. Full engine power is now available for takeoff, climb, cruise and effective propeller braking is available to slow the aircraft down on landing.
