Measuring Technique and Metrology
Central Aerohydrodynamic Institute named after prof. N.E. Zhukovsky (TsAGI) — is one of the major centers of world aeronautic science. A wide scope of fundamental and applied researches in aerodynamics, flight dynamics, static strength, aircraft lifetime and safety is performed in the institute. The unique experimental base that includes more than 60 wind tunnels and hydrodynamic installations, static and dynamic strength laboratories and flight simulators is at disposal of TsAGI.
To meet the becoming ever-tougher requirements of up-to-date experiment the fundamental and applied researches and developments are performed in institute. These activities aim to enhance the available measuring means and methods and to design the innovative ones, the greater part which of are of world priority level.
To enhance the experimental research cost-efficiency and informativity a number of measuring and computing integrated systems of new generation is developed and implemented successfully at TsAGI in order to improve the accuracy and information content of the experimental research. In Russia TsAGI plays a leading role in development of the strain-gage method to measure forces and pressures; the optical-physical methods and measurement means are developed and widely used. The special standards for checking the metrology system accuracy characteristics are created that have no analogues in RosStandard organizations.
Development of new techniques and means for experimental researches at TsAGI significantly facilitates the progress of future aeronautic science in Russia.
