Engineers of the Flight Test and Refinement Complex (LIiDK) of PJSC "Yakovlev" at the airfield in Zhukovsky began ground tests of all systems of the SJ-100 prototype with tail number 97021 as part of preparations for certification tests.
Yakovlev engineers checked the operation of individual elements of the landing gear struts, including extension and retraction. They will also test the aircraft's doors and hatches, cabin pressurization, and the availability of rapid evacuation.
Experts will assess the correct operation of all onboard instruments, and the indication in the cockpit of the SJ-100. During the tests, they will monitor the mobility of ailerons, flaps and other aircraft guides.
LIiDK faces many tasks within the MC-21 and other projects. The gradual integration of our flight test complexes into a single whole is also of particular importance
The SJ-100 aircraft with tail number 97021 arrived in Zhukovsky from Komsomolsk-on-Amur at the end of April after completing refinement tests at the factory. To speed up certification, the aircraft was equipped with SaM146 engines of Franco-Russian design. At the same time, the key systems of the aircraft remained Russian.
