AP332CTF-WWR75W

Airmaster Propeller System

The AP332CTF-WWR75W is a three blade propeller for use on the Rotax 9 series of engine. Its configuration is clockwise/tractor with the addition of a feathering facility.

The performance gain from the AP3x constant speed hub, combined with the outstanding design of the Whirlwind W series blade, make this the ultimate STOL propeller. If you have the room to swing 75in, then the 75W gives more STOL performance on a Rotax engine than any other propeller.

Features include

Designed for Rotax 9 series engines
High strength AP332 CS hub with steel retention components
Fast response from high precision Maxon servo drive
Max STOL performance from Whirlwind 75W blades
Hard wearing composite blade construction with inlaid Nickel leading edge protection
Easy to use AC200F electronic governor/controller
Easy installation with a wide range of pre-made installation kits

Precision Hub Mechanism At the heart of each Airmaster propeller is a high quality hub mechanism. The single piece hub shell and steel retention parts ensure the hub is lightweight and strong. The high quality aerospace materials used throught the hub ensure a long life with superior fatigue resistance. High strength single piece shell Precision pitch change mechanism Durable steel retention components Fast and reliable electric PC motor
	Simple Operation The Airmaster propeller is extremely simple to operate thanks to the AC200 control system. The automatic management of the engine rpm is essential in reducing pilot workload during the critical phases of flight like landing and taking off. Easy selection of engine speeds for Take Off, Climb and Cruise Flexible speed selection using Hold function Precise speed regulation from solid state governor Clear pilot feedback of propeller operation Semi automatic 'Feather' function
High Aerodynamic Performance Airmaster propellers offer the 75W blade from Whirlwind, for exceptional STOL performance and high durability. The high temperature cure prepreg carbon technology ensures an exceptionally stiff, lightweight blade. This increased strength allows thinner sections and more complex shapes to be formed resulting in highier efficiencies, over a wider speed range. The WWR75W blade from Whirlwind (USA) offers many features useful to modern Rotax powerered aircraft. Modern aerodyanmic design ensuring good cruise speeds Very large 75in diameter for ultimate low speed thrust Strong and lightweight hollow carbon construction High gloss natural carbon finish with white tips gives good looks and long life Tapered blade tip giving quiet and efficient operation Fully shaped nickel leading edge protecting the leading edge
	Easy installation The installation of the propeller is very straight forward and is designed to be accomplished in a short time by any competent layperson. Included is a very comprehensive operators manual and propeller log book. The propeller comes pre-lubricated and statically balanced with all the necessary hardware supplied. Pre-lubricated Pre-balanced Pre- finished wiring Detailed manual Assembly boms
