How does a feathering propeller work?

With a feathering prop, the blades are symmetrical and rotate around a central pivot point and offer as much thrust in reverse as they do in forward gear — a boon for getting into a tight slip. When sailing, the blades align themselves with the flow of water, reducing drag.

What is Auto feathering?

Autofeather is a feature of the engines on some turboprop or piston engine aircraft. When the power being produced by the engine drops to the point where it is not contributing to thrust, the propeller will go into a feathered mode to reduce drag.

What is meant by feathering?

Feathering is a technique used in computer graphics software to smooth or blur the edges of a feature. The term is inherited from a technique of fine retouching using fine feathers.

How do you feather props in War Thunder?

Toggle Engine controls mode.

What happens when you feather a propeller?

The inflight feathering of the propeller, on an engine that has failed or has been intentionally shut down, greatly reduces the drag that would occur with the blade pitch in any other position.

What is full feathering propeller?

A full-feathering propeller system is normally used only on twin-engine aircraft. This eliminates asymmetric drag forces caused by wind milling when an engine is shut down. A propeller that can be pitched to this position is called a full-feathering propeller.

What is the purpose of feathering?

This process is referred to as feathering. The inflight feathering of the propeller, on an engine that has failed or has been intentionally shut down, greatly reduces the drag that would occur with the blade pitch in any other position.

How do you describe a feather?

A feather is one of the soft, fringed plumes that cover the bodies of birds. Some feathers are tiny and downy, while others are large and brilliantly colored. Scientifically, feathers are described as growths or appendages that form on a bird’s skin — but this definition can’t capture how lovely feathers are.

How do you prop feathers?

Most feathering systems for reciprocating engines sense a drop in oil pressure and move the blades toward the feather position, and require the pilot to pull the propeller control back to disengage the high-pitch stop pins before the engine reaches idle RPM.

What happens when you feather the propeller on an airplane?

When the engine fails, the non-feathered propeller will simply spin about slowly, making it more of a hindrance than a help. Feathering the propeller puts the still spinning prop into a low-drag state (think palm down from the earlier experiment) which will make flying the airplane a bit easier with the loss of an engine.

Is there a way to turn off prop feathering?

Prop feathering will still be turned on when we switch back to the good engine. There is currently no way to deactivate prop feathering while we have no engines selected, and the game will think we want to feather engine one when we reactivate the controls.

When do you use feathering in an aircraft?

Feathering is not engine starting, and also is not used in turbine (excluding turboprop) aircraft. In a piston or turbo prop aircraft, in the event of an engine failure, to decrease drag so you can either glide farther or have better performance on the remaining engine(s), you can set the prop pitch lever so instead…

Which is better feathered prop or free spinning prop?

Yes glide and performance with a feathered prop is better than one spinning in the air like a kid with a pinwheel. But those are happy side effects due to the significant reduction in drag and adverse yaw caused by a free-spinning prop. Moreover a runaway prop can be deadly. The prop can far exceed its normal RPM limits and come apart!
