General information

Name of the project: Computational and experimental aerohydromechanics, aerodynammics and aeroacoustics of helicopters

Goals and objectives

Research directions: Mathematics and mechanics

Project objective: Development of instrumental means and methods of physical and numerical modeling in problems of designing aerodynamic layout of helicopters

The practical value of the study

Scientific results:

  1. The Laboratory has created a complex of measurement and computation tools and methodologies for conducting the experiment and a mathematical modeling  in the  aerodynamics and aeroacoustics of helicopters, a database of results of experimental and numerical modeling.
  2. We have created a database of construction elements of designs of helicopter fuselages for the purpose of assessing their impact on helicopter aerodynamics and verifying numerical moldering methods.
  3. Our researchers have created designs for a number of commercially manufactured light aircraft and drones.
  4. Using the genetic algorithm, we have developed a methodology for optimizing helicopter fuselages for the purpose of decreasing the aerodynamic resistance.
  5. We have developed a methodology for researching the influence of the shape of the tip of a rotor blade on the aeroacoustic characteristics of the main rotor of a helicopter in the near and far field.
  6. A methodology has been developed for determining load distributions across the surfaces of the disk of the active rotor for horizontal flight.
  7. We have proposed a modification of a criterion for determining of the position of the core of the rotor blade tip vortex with the use of the results of a numerical and physical modeling. 

Implemented results of research:

  • For the «Russian Helicopters» holding company we have analyzed the modern state and  prospects of the development of structural elements of designs of helicopters and on-board radio-electronic equipment.
  • We have proposed design solutions for  the optimization of the shape of the fuselage of the «Ansat» helicopter («Russian Helicopters» OJSC) for the purpose of improving its flight quality, technological and economic indicators.
  • In collaboration with the Central Aerohydrodynamic Institute — TsAGI we have conducted a research to measure the shape of the cargo compartment of the Mi-8 helicopter type to improve the aerodynamic characteristics of the helicopter. We conducted research to investigate the aerodynamic characteristics of a convertoplane that is taking off veritably. 
Education and career development:

  • For the Kazan National Research Technical University we have developed and are currently delivering lectures in the disciplines «Mathematical modeling and computational methods in aeromechanics», «Numerical methods of sovling problems in aerodynamics», «Design of helicopters», «Design of components of helicopters».
