Without a method of converting the power produced by the engine into useful thrust an aircraft would just be sitting still and creating a lot of noise and not get anywhere. In the past, all kinds of different propeller designs were tried: sometimes flat wooden blades, from one bladed counter weighted to multiple blade models rotating at various speeds.
Variable pitch propellers have a distinct advantage compared to fixed pitch models. This translates into a more fuel efficient, higher performing aircraft with much improved rate of climb and shorter takeoffs for those tight places!
The McCauley story begins in Dayton, Ohio, when Earnest G. McCauley, a pioneer in the field of aerodynamics and holder of numerous patents on controllable propellers, founded the McCauley Aviation Corporation in 1938. In the still expanding field of aviation, he determined that propeller and engine compatibility was crucial to achieving maximum efficiency and performance from an aircraft. McCauley built his company around this fundamental, significant and essential idea.
For more than six decades, McCauley has set the standard for innovative propeller design. Their engineering and performance accomplishments are unequalled in the industry. The line of piston and turbine propellers continues to push performance to new limits for every aircraft that uses them. McCauley's family of propellers is as diverse as it is durable, below a small overview.
A full line of aluminum fixed pitch propellers for single engine aircraft provides maximum performance and minimum operating costs.
Already in use with thousands of single engine aircraft, this propeller type is highlighted by McCauley's unique one piece, oil filled hub with a threadless blade retention system. That means greater dependability, coupled with low cost and high performance, a win win!
When these were introduced more than 30 years ago, McCauley's full feathering propellers for reciprocating twin engine and turbine powered aircraft utilized many of the design features found on the constant speed models. Since then, product enhancements that were specifically developed for full feathering propellers, like the oil filled hub and threadless blade retention, have become standard, not just on these models but also on all constant speed models.
The innovation McCauley builds into every one of their propellers comes out as an unique benefit. Benefits such as unequalled performance, unsurpassed safety and reliability. Every standard OEM propeller and every BLACKMAC STC model delivers advantages found only from McCauley. Below are just some of the reasons why McCauley provides high value to their customers.
McCauley's control system family is divided into two major and distinct product groups. The first group is a constant speed governor which is designed to deliver engine oil to the propeller to increase pitch. The second is a feathering governor which is designed to deliver engine oil to the propeller to decrease pitch.
Spinners were introduced to the product line in 1957, they serve both cosmetic and functional purposes. In addition to enhancing aircraft appearance and looks on the platform, spinners reduce unwanted drag by streamlining the airflow which provides much improved engine cooling and ram air intake on aircraft.
