TsAGI introduces into operation a new hydraulic system to study loads on aircraft actuators

16 November 2016

The Central AeroHydrodynamic Institute named after professor N.E. Zhukovsky (TsAGI, part of the National Research Center “Institute named after N.E. Zhukovsky”) conducts works on modernization of the experimental facilities of the Flight Dynamics and Control Systems Department.

At the present time, specialists are introducing a new hydraulic system in the testing process. The equipment is designed for power supply to the hydraulic power loaders, which are then used to simulate flight loads on aircraft control actuators, such as elevators and rudders, ailerons and mechanization elements. This system, which is a standalone oil pump station, also can supply hydraulic power to the actuators, in the same manner as it occurs during a real flight. The key advantage is more powerful equipment, if compared with previous apparatus. This allows scientists to study simultaneously several actuators and to simulate the loads that may occur on these actuators during actual operation of the aircraft.

Sergey Bazhenov, the Head of the Flight Dynamics and Control Systems Department, explained: “Thanks to the new hydraulic system, we will be able to reproduce with higher accuracy the flight operational conditions of the actuators and to analyze their actual performance. In particular, the use of this equipment can be indispensable in the studies of large unmanned aircraft controls — their actuators consume a lot of electrical power and are fault-critical.”
