A governor is an engine rpm-sensing device and high-pressure oil pump. In a constant-speed propeller system, the governor responds to a change in engine rpm by directing oil under pressure to the propeller hydraulic cylinder or by releasing oil from the hydraulic cylinder.

The component in charge of it all is called the governor. The governor moves oil back and forth through the propeller hub to make sure the prop is at the pitch and speed that you want. There are several parts to the governor that make everything happen. Let's take a look at what they all do:

2022年7月22日 · The prop governor is nothing more than an externally mounted oil pump that selectively “leaks” oil pressure from anywhere between 50 to 280 PSI as needed to the prop hub. There, it’s converted to mechanical piston motion to effect prop blade pitch changes.

AMERICAN PROPELLER provides new governor sales, overhaul services, exchanges and technical support for all major governor manufacturers including McCauley, Hartzell, MT-Propeller, Woodward, Hamilton Standard, Aero Technologies and Jihostroj.

2024年4月18日 · Propeller governors significantly enhance aircraft control by regulating engine speed and maintaining optimal propeller performance. These systems allow pilots to adjust thrust settings efficiently, ensuring consistent and stable flight …

Hartzell governors are available with the following features: • Normal or High Capacity • Feathering • Synchronizing • Synchrophasing. Use our Application Guide help you find the right propeller system for your aircraft or engine/airframe combination.

In a single-acting propeller system, oil pressure supplied by the governor, acting on the piston produces a force that is opposed by the natural centrifugal twisting moment of the blades in constant speed models or counterweights and large springs in full-feathering systems.

2012年1月5日 · Constant speed propellers allow the pilot to optimize performance by setting a desired rpm. The system then changes the blade angle constantly to ensure that rpm value is met. Oil from the engine applies constant pressure to a closed system called a governor. The governor consists of pivoted flyweights, a spring, a hollow gear drive shaft.

A prop governor is a device which automatically adjusts the angle of the aircraft propeller blade as necessary to maintain a constant engine speed under varying flight conditions. The range of adjustment of the prop governor is limited only by the blade angle range of the propeller.

2023年9月15日 · The prop governor is a variable speed and variable control oil pump that utilizes a combination of mechanical and hydraulic systems to adjust the angle of your aircraft propeller blades. The governor increases or decreases oil pressure against your propellers, adjusts their pitch, and responds to changes in flight conditions and pilot inputs in ...
