TsAGI conducted aerodynamic and strength tests of the SJ-100 aircraft model with PD-8
engines
Scientists of the Central Aerohydrodynamic Institute named after Professor N.E. Zhukovsky (TsAGI) continue research work on the import-substituted SJ-100 aircraft. This time we carried out aerodynamic and strength tests of a model of the airliner with PD-8 aircraft engines.
Researchers simulated the run of an aircraft along the runway after touching down at speeds of up to 80 m/s, and simulated the operation of the reverse for various wing mechanization configurations. The plane's run along the runway after touching down was also simulated.
As noted at TsAGI, for the new series of experiments they used the method of spatial visualization of the PIV flow (Particle Image Velocimetry — anemometry by particle images). Another feature of the work was the use of high-frequency sensors, with the help of which the static pressure was measured on the surface of the horizontal tail.
