TsAGI continues Yak-152 test cycle
11 October 2017
In late September specialists of the Zhukovsky Central AeroHydrodynamic Institute (TsAGI, a member of the National Research Center "Zhukovsky Institute") completed the next stage of the static testing of the Yak-152 training aircraft.
Having studied the wing, the pilot canopy, the horizontal tail assembly, and the underside structural stress and deformations, the scientists focused their attention on the undercarriage. They designed, manufactured and set up special test facilities where they conducted static tests of the nose-gear hinge fittings for four load scenarios and main landing gear for seven load scenarios. The tie-down restraints of the undercarriage in the stow position demonstrated the required level of its strength.
The next phase was the static testing of the pitch control system, which yielded positive results. Next, the research team plans to carry out pilot positioning and aircraft engine attachment tests.
“Hinge fittings of undercarriage and aircraft construction successfully withstood the load,” said Victor Tsygankov, the head of TsAGI’s Static and Thermal Strength Department. “The integrity of tie-down restraints also met aviation requirements. This means that the aircraft has successfully passed all the static tests so far.”
The Yak-152 is a single-engine, two-seat flight trainer 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 techniques, navigation fundamentals and the principles of group flights. The aircraft development project started in 2014; the first aircraft flew in September 2016.
