TsAGI resumes helicopter workshops
9 January 2017
In December, the Central AeroHydrodynamic Institute named after professor N.E. Zhukovsky (TsAGI, part of the National Research Center “Institute named after N.E. Zhukovsky”) held the regular meeting of the research workshop of the Helicopter Aerodynamics and Dynamics, Aircraft High-angle Spins and Aerodynamics Division. Aleksander Nikolsky, the leading research associate of the Division, presented the paper: “Mathematical models and applied aerodynamics methods of helicopter profiles.”
The significance and high value of the development lies in the fact that some of its outcomes are applied even now to main and tail-rotor blades of prototype helicopters. Thus, a main rotor of the innovative layout (that is of advanced profile layout and geometry) has been designed for a flying test-bed of an advanced high-speed helicopter. Its efficiency consists in significant upgrade of rotorcraft performance, in particular, in lower vibration and noise.
This meeting was the sixth one within the framework of the workshop devoted to helicopters and other research issues of the Division. The range of topics dealt with in previous meetings had been quite diverse. Papers on current phenomenology (results of experiments) of aerodynamic characteristics of main rotor large-scale models; application of a vortex method to solving related tasks of aircraft high-angle aerodynamics and dynamics; development of calculation methods for research of aircraft high-angle and spin aerodynamics; analysis of air flows on the surface with the use of a frequency and wave spectrum and a variable curvature profile mechanism, had already been presented.
Scientific meetings of similar type are planned to be held bi-monthly.
