General information

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

Strategy for Scientific and Technological Development Priority Level: а


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

  • We have created a complex of measurement and computation devices, methodologies of experiments and mathematical modeling in the domain of helicopter aerodynamics and aeroacoustics.
  • The Laboratory has conducted research of aeroacoustics of the rotor wing of a multifunctional helicopter in the near and the remote range including research of various winglet shapes.
  • In collaboration with the Central Aerohydrodynamic Institute – TsAGI we have been conducting works in experimental and numerical modeling of the structure of air flow near lifting surface areas of various types.

Implemented results of research:

  • The Laboratory has compiled proposals for optimizing geometry of the fuselage of a light multi-purpose helicopter (for the Kazan Helicopter Plant) to improve its aerodynamics and to reduce harmful resistance, improving economic competitive ability and technical indicators.
  • We have developed layouts for a number of mass-manufactured light aircraft and drones.
  • A unique noise-proof chamber in an aerodynamic tube with an open working area. It does not have analogs in Russia and can be used for an aeroacoustic experiment with the main rotor of a helicopter in the near range.

Education and career development:

  • We have organized internships of 9 members of the academic staff of the Laboratory at universities at Liverpool and in other European university.
  • One doctoral dissertation and 6 candidate dissertations have been defended.
  • The Laboratory has published the monograph «Analysis of the modern level of development of helicopter technologies around the world».
  • We have developed a methodological and educational guidebook «Aerohydrodynamics».
  • The additional training course «Modeling aeroacoustic radiation in solving problems of external aerodynamics» has been developed.
  • Over 60 young professionals from other organizations have completed their additional training at the Laboratory.

Other results:

We have conducted international scientific conferences: «New technologies, materials and equipment of the Russian aircraft industry» (2018); «Problems of modeling and dynamics of complex interdisciplinary systems», the thematic session «Modern fundamental and applied problems of mechanics: Methods, models, applications in the aircraft and space industry» (2017); the 11th International Chetayev Conference «Analytical mechanics, stability and control» (2017);  «Tupolev's readings» (2017), «Problems and prospects for development of the aircraft industry, ground transportation systems and the power industry» (2015)

Collaborations: Central Aerohydrodynamic Institute – TsAGI, Kazan Helicopter Plant, Russian Helicopters Holding Company: joint scientific research
