IL Planes 120 Anniversary: a Peek into IL Labs

Posted on April 4, 2014 by tim

The 120th anniversary of the famous Russian airplane creator, Sergey Vladimirovich Ilyushin, was celebrated in the House of Scientists yesterday. Here are some photos of the testing department of “IL” airplanes.

The creation of any aircraft is a long and complicated process. It includes a lot of tests, including tests for structural strength. During static and fatigue tests, the calculated limits and working loads are confirmed experimentally. Tests confirm the accuracy of the design process under the specified load, and the question of the accuracy of the load is answered by using flight strength tests.


There are two independent disciplines of strength calculations. The first is a calculation of strength and the second is a static calculation of the resource.

The wing, as the most vital part of the aircraft structure, is tested with calculated loads up to 120%. The fuselage has tests on 100% load.
