A twin-engine aircraft is fitted with single-acting propellers and counterweights. In the case of a complete failure of an engine, what will the propeller of the affected engine do?

Answer :

Final answer

In the event of a complete engine failure, the propeller of the affected engine will feather automatically. This is due to the presence of the single acting propellers and counterweights.

Explanation

When we talk about aircraft propellers, one of the critical features to understand is the feathering mechanism. Feathering means adjusting the blades of a propeller so that they are parallel to the airflow. This reduces drag and is particularly useful when an engine fails in flight.

Single acting propellers equipped with counterweights are designed to feather automatically upon engine failure. Here's how it works step by step:

1. Under normal operations, the oil pressure from the engine pushes against the counterweights, holding the propeller in its operational pitch (often a fine pitch for takeoff and climb).

2. When there's an engine failure, the oil pressure drops immediately. Without the oil pressure to counteract them, the counterweights come into play.

3. The counterweights, due to their design and placement, force the propeller blades to rotate into the feathered position. This means the blades align themselves almost parallel to the oncoming airflow.

4. By feathering the propeller, the drag is significantly reduced. This is essential for twin-engine aircraft as it allows the aircraft to maintain a safer and more controlled flight on the remaining working engine.

5. While the process sounds manual, it's all automatic. As soon as the engine detects a failure (primarily through the loss of oil pressure), the counterweights immediately start the feathering process without pilot intervention.

Feathering propellers are a critical safety feature for multi-engine aircraft, ensuring that if one engine fails, the drag from a windmilling propeller (a propeller freely rotating due to the wind) doesn't hinder the aircraft's performance. By automatically feathering the propeller, it aids the pilot in maintaining control of the aircraft and allowing for a safer emergency landing or continued flight on the other working engine(s).
