Ground-Adjustable Propeller The ground-adjustable propeller operates as a fixed-pitch propeller. The pitch, or blade angle, can be changed only when the propeller is not turning. This is done by loosening the clamping mechanism that holds the blades ... tightened, the pitch of the blades cannot be changed in flight to meet variable flight requirements. The ground-adjustable propeller is not often used on present-day aircraft. Controllable-Pitch Propeller The controllable-pitch propeller permits a change of blade…
- Chapter 7: Propellers › Propeller Location › Pusher Propellers
Pusher Propellers Pusher propellers are those mounted on the downstream end of a drive shaft behind the supporting structure. Pusher propellers are constructed as fixed- or variable-pitch propellers. Seaplanes and amphibious aircraft have used a greater percentage of pusher ... propellers than other kinds of aircraft. On land aircraft, where propeller-to-ground clearance usually is less than propeller-to-water clearance of watercraft, pusher propellers are subject to more damage than tractor propellers. Rocks, gravel, and small objects dislodged…
- Chapter 7: Propellers › Propeller Aerodynamic Process › Propeller Controls & Instruments
Propeller Controls & Instruments Fixed pitch propellers have no controls and require no adjustments in flight. The constant-speed propeller has a propeller control in the center pedestal between the throttle and the mixture control. [Figure 7-10] The two positions ... control are increase rpm (full forward) and decrease rpm (pulled aft). This control is directly connected to the propeller governor and, by moving the control, adjusts the tension on the governor speeder spring. This control can also be used…
