Model 8700 Aircraft Roll Dynamometer


The LINK Roll Dynamometer is utilized for laboratory testing of aircraft wheels for measuring the performance of wheel designs. The roll machine is capable of performing controlled load applications to reproduce radial forces acting upon the wheel per endurance test requirements and standards. Yaw and camber angles are adjustable to induce side load.

The roll is hardened to allow for conducting Roll-on Rim testing. Radial load is applied and controlled by means of a servo valve, hydraulic cylinder and hydraulic power unit. Tire pressure is controlled remotely through a rotary coupling for automatic inflation and deflation.
