A prototype of the wing box MS-21 tested for strength

TsAGI ("Central Aero-Hydrodynamic Institute named after Professor NE Zhukovsky") completed strength testing of the prototype caisson composite wing. Studies were carried out on the request of JSC "AeroComposite" within the promising short-medium range aircraft MS-21.

Static tests have completed the set of strength studies and determined the limit load for a given instance of the prototype wing box. In the course of one of the most important tests of the prototype has been applied to an extreme load, the destruction occurred in the expected area.

In the previous steps have been carried out successfully and the frequency and stiffness testing of the prototype caisson, in which were deposited on a prototype artificial potential in the production and operation of defects and damage.

Studies have confirmed the compliance of design models and design parameters of the caisson embedded in the design phase. The data will be used for further engineering MS-21.

Measurement results supplement database for subsequent use certification and strength composite structures, including taking into account the regulated shock damage.

According to the head of the complex strength aircraft TSAGI Michael Zichenkova, during the testing process has provided important information to improve the testing methods of large composite structures of power. "The unique strength of the base of the complex aircraft TSAGI allowed the highest modern standards to hold such a complex and time-consuming research," — said Mikhail Zichenkov.

Currently, the TsAGI began work in preparation for the next instance of the resource test prototype composite wing box. The entire complex computational and experimental studies aimed at ensuring the safety of the terms of strength, aero-elasticity and resource aircraft with a composite wing.
