TsAGI successfully completes Yak-152 static tests

23 May 2018

Specialists of the Zhukovsky Central AeroHydrodynamic Institute (TsAGI, a member of the National Research Center “Zhukovsky Institute”) conducted the final stage of strength static tests of the Yak-152 trainer aircraft. The aircraft successfully withstood the loads and did not suffer permanent distortion.

The full cycle of experiments lasted for more than a year. TsAGI structural engineers at the preparatory stage designed and installed loading systems, prepared instrumentation, and loaded an automated control system. Then engineers successively tested the wing, pilot canopy, fuselage, wing mechanization, undercarriage, engine hinge fittings, pilot seat attachment structure and engine attachments, control wiring, and vertical and horizontal stabilizers. At each step the experts brought their efforts first to operational and then calculated (i.e. limiting) values and measured the intensity and deformations in the design.

The obtained experimental data confirm the aircraft meets domestic standards. In addition, TsAGI will give recommendations to remove speed and loading intensity restrictions, imposed after the first Yak-152 flight in 2016.

The Yak-152 trainer aircraft was designed at OJSC Design Bureau named after A. S. Yakovlev and built at the Irkutsk Aviation Plant, a branch of PJSC Irkut Corporation. The aircraft differs from all previous models of this class by its better flight performance characteristics and cutting-edge piloting and navigation equipment.
