Application and Development Trend of Annular Damped Hinge in Aerospace Field

Annular damped hinge, also known as ring damper hinge, is a mechanical device that can provide damping in rotational movements. It is widely used in aerospace field due to its ability to reduce vibrations and increase stability of the system. In this article, we will discuss the applications and development trend of annular damped hinge in aerospace field.
Applications:
Aircraft Control Surfaces:
Annular damped hinge is used in aircraft control surfaces, such as ailerons, rudders and elevators. These control surfaces are responsible for maneuvering the aircraft in different directions. The annular damped hinge can provide damping in the rotational movements of these control surfaces, reducing the vibrations caused by turbulence, gusts, and other disturbances, and thus improving the stability and control of the aircraft.
Helicopter Rotor Blades:
Helicopters use annular damped hinge in rotor blades. The rotor blades are responsible for generating lift and controlling the movement of the helicopter. The annular damped hinge can provide damping in the rotational movements of rotor blades, reducing the vibrations caused by rotor blade flapping and lagging, and thus improving the stability and control of the helicopter.
Spacecraft Deployment Mechanisms:
Annular damped hinge is also used in spacecraft deployment mechanisms. These mechanisms are responsible for deploying solar panels, antennas, and other equipment in space. The annular damped hinge can provide damping in the rotational movements of these deployment mechanisms, reducing the vibrations caused by the deployment process, and thus ensuring the proper functioning of the equipment.
Development Trend:
Lightweight Design:
The trend in aerospace industry is to reduce the weight of the aircraft or spacecraft in order to improve their performance and reduce their fuel consumption. Annular damped hinge is no exception. The development trend of annular damped hinge is towards lightweight design, using advanced materials and manufacturing processes to reduce the weight
