Brief

    The Central Aerohydrodynamic Institute (TsAGI) was founded on December 1, 1918 under the initiative and leadership of N. E. Zhukovsky, the father of Russian Aviation. Today’s TsAGI is the largest scientific research center in the world. Under the Russian Federation Government Decree No.247 of March 29, 1994 TsAGI was designated a State Research Center. It was the first scientific institution to combine basic studies, applied research, structural design, pilot production and testing. During its distinguished history TsAGI has developed new aerodynamic configurations, aircraft stability/controllability criteria, and strength requirements. TsAGI was a pioneer in the theory of flutter along with many other theories, applications and experimental studies.

    During the last two decades TsAGI has achieved significant advances in Aerodynamics, Flight dynamics and Flight control systems, as well as improving static material strength, service life and reliability of civil airplanes. Our methods for structural analyses and optimization make it possible to reliably design new-generation aircraft so as to ensure a 50,000- to 60, 000-hour service life. These results were applied while developing the Tu-204 (by General Designer A. A. Tupolev) and the Il-96—300 (by General Designer G. V. Novozhilov). In the 1980s the TsAGI’s scientists worked on improving the maneuverability of modern fighters. Solutions were obtained for many problems concerning the aircraft control when flow separation conditions took place at high incidences. This is demonstrated in the maneuverability of the MiG-29 (by General Designer R. A. Belyakov) and the Su-27 (by General Designer M. P. Simonov) and has been verified through performance of the «Pugachev Cobra» maneuver.

    While developing the «Energia» launcher and the «Buran» reusable aerospaceplane, TsAGI made significant investigations into aerogasdynamics and flight dynamics, assessing structural strength for velocities from orbital to landing. These new designs met challenges of hypersonic flight physics, new control systems for a wide range of velocities, while mathematically modeling numerous processes and studying a wide range of motion on flight simulators.


Research

Fundamental investigation of structural static/fatigue strength. This includes:
– Specifying the load spectra and environmental factors;
– Analytical and experimental evaluation of the stressed state;
– Structural optimization under conditions imposed by static strength, thermal strength,aeroelasticity, fatigue and crack resistance;
– Determination of the aeroelasticity-critical parameters of aircraft including an aircraft equipped with an automatic control system;
– Study of thermophysical, thermochemical and radiation properties of thermal protection/insulation materials, their catalycity and service life;
– Study of thermal strength of thermal protection/insulation, internal and external heat exchange.

Practical work with designers and industry, including:


– Development of Structural Strength Requirements for particular aircraft;
– Development of structural analysis methods for aeronautical structures of current interest;
– Development of strength test methods & programs and acceptance procedures;
– Development of advanced thermal protection means;
– Participation in the strength certification of particular vehicles.

Development and improvement of test facilities, stands, wind tunnels, data acquisition systems, and software to control tests and to process test results. In order to solve the above problems, TsAGI has developed corresponding methods of analysis, and has acquired the necessary test equipment:


– Static test laboratory, which enables the testing of aircraft, weighing up to 250 tons;
– Fatigue test laboratory, which enables the testing of aircraft, weighing up to 300 tons;
– Thermal test laboratory, equipped with 9 thermo-vacuum chambers of varying size, including a unique thermo-vacuum chamber with a volume of 4500 m3,enabling the testing of structures in the temperature range 100-1750K and pressure from normal to 0.1 Pa;
– acoustic chamber, 1600 m3 in volume, with maximum acoustic load level of 164 dB;
– Element/subcomponent test laboratories equipped with many electro-hydraulical and electro-mechanical test machines, to test samples, structural elements, and subcomponents under a load of up to 1000 tons;
– Complex of wind tunnels (conventional, shock, hot shot)providing a broad range of Mach numbers (up to M=20) and Reynolds numbers (up to Re=2.3 107 );
– Wind tunnels with arc jet heaters, creating air temperature up to 4500K and pressure up to 30 bar;
– Setups with air induction heaters, providing high cleanliness of gas and plasma flow, which simulates the flight at altitudes from 60 to 300 km;
– Setups for studying the thermophysical and radiative properties of thermal protection materials.

Among TsAGI results in the field of interest over the last 15-20 years, the following are worthy of note:


– Test of more than 500,000 small samples, structural elements and thermal protection elements;
– Support of development of about 30 types of aircraft and spacecraft;
– Tests of about 20 types of aircraft and spacecraft;
– Certification/qualification of about 30 types of aircraft and spacecraft;
– Issue of about 40 basic Strength Regulations/Requirements;
– Investigation of several flight accidents.
