TsAGI completes Yak-152 strength tests
14 September 2017
At the beginning of September, the specialists of the Zhukovsky Central AeroHydrodynamic Institute (TsAGI, a member of the National Research Center" Institute named after N.E.Zhukovsky") completed another stage of static strength testing of the Yak-152 training aircraft.
The scientists investigated the behavior of the aircraft components under structural stress and deformations, receiving positive results for the wing and pilot’s canopy. They finished preparations for the joint static tests of wing mechanization (flaps and aileron), as well as the rudder and horizontal tail assembly. The undercarriage, engine hinge fittings and steering linkage will be studied in the future.
“We simulate aerodynamic effect on the individual structural components, and then on the entire machine,” stressed Victor Tsygankov, the head of TsAGI’s Static and Thermal Strength Department. “If a wing successfully withstands the loads equal to operation and close to computed values, this allows us to remove some maneuver limitations on an aircraft.”
The Yak-152 is a flight-training, single-engine two-seater aircraft used for initial training and professional selection of pilots. It is expected that students in training establishments will be able to learn entry level flight technique, navigation fundamentals and the principles of group flights. The aircraft development project started in 2014 and the first aircraft flew in September 2016.
