TsAGI puts into operation programmable movement stand for models

18 May 2017


The experts of the Central AeroHydrodynamic Institute named after professor N.E. Zhukovsky (TsAGI, part of the National Research Center “Institute named after N.E. Zhukovsky”) have developed and put into operation a multi-grade stand for programmable movements of aircraft models.

This stand is intended for the study of the characteristics of an aircraft during maneuvers — when changing angle of attack, skid, etc. These characteristics are unsteady and influence the stability and controllability of an aircraft.

The stand will be used for tests in TsAGI’s subsonic wind tunnel. This setup will allow simulating linear and angular movements at any degree, as well as all complex movements of an aircraft model.

“This stand provides us with new qualitative opportunities for studies,” explained senior researcher of Dynamics and Control Systems for TsAGI aircraft and Candidate of Technical Sciences Vladimir Markov.. “It is an advanced development in a league of its own in our country. It will help to save significant amount of test time, as it does not require reinstallation of the stand for reproducing different types of movements of a model. The Multigrade system allows us to simulate maneuvers of any aircraft.”

Institute experts successfully performed with the help of this stand studies of unsteady aerodynamics characteristics of a passenger long-range aircraft model under different angles of attack and skid. The data received from the results of these tests will be processed and analyzed, and then used for the creation of mathematical models of dynamic motion of an aircraft under study.

The next test run is planned for the end of this year. TsAGI scientists plan to study the new passenger long-range aircraft model in a wider range of speeds and Reynolds numbers.
