This angle is called the zero-lift angle of attack. In this … Webon the aircraft by feathering the propeller in the event of an engine shutdown. Efficiency and speed control. Since all turbine engines are most efficient within specific RPM ranges, it is desirable to have a propeller with the ability to change thrust while maintaining the most efficient engine RPM possible. In a Webfailure is to immediately “feather” the propeller on the aﬀected engine. The purpose for feathering is to align the propeller blades into the wind stream. This action provides minimum drag from the failed engine. The aircraft would then be more controllable with thrust from the “good” running engine. fairview nursery raleigh

What does feathering mean and how does it work …

WebMar 3, 2024 · Constant speed propellers work by varying the pitch of the propeller blades. As the blade angle is increased, it produces more lift (thrust). At the same time, more force (torque) is required to spin the prop, slowing the engine down. The opposite is true when the blade angle is decreased: the torque required is decreased, and the engine speeds up.
