What type of strut is designed to reduce rapid extension during landing gear operation?

The type of strut designed to reduce rapid extension during landing gear operation is an air-oil strut. This system utilizes a combination of air and oil to provide effective cushioning and damping as the landing gear is deployed and retracted. The air in the strut acts as a spring, while the oil helps to control the movement, preventing sudden or harsh extensions that could damage the landing gear or aircraft.

This design is crucial for protecting the integrity of the landing gear during the landing process, where forces can be significant, and for ensuring a smoother retraction and extension cycle. The ability to manage the rate of extension contributes to the overall safety and performance of the aircraft during takeoff and landing operations.
