The composite wing of the new Russian "Tango" training aircraft successfully withstood static tests with a total load of over 4 tons. This was reported by the "Tekhnosfera Rossiya" publication, citing the project developers and Spectra Aircraft, where the next stage of the factory testing program was completed in June 2026.
During the tests, specialists checked the strength of the wing consoles before their final mating with the center section. The structure confirmed compliance with the design parameters and maintained the necessary characteristics after the application of test loads.
The "Tango" aircraft is entirely built using modern composite materials. The fuselage, wing, spars, and tail unit are made of carbon fiber and other polymer composites. Some of the materials are supplied by Rosatom.
During the tests, engineers changed the control methodology. Before reaching half of the design load, preliminary equipment setup was performed at 30% of the required values. Climatic conditions, maximum and residual deformations of the structure were additionally controlled, and all stages of the tests were recorded simultaneously by six cameras.
After modernizing the test center section, which received a universal installation scheme, the wing consoles underwent ultrasonic inspection and leak testing. The load was applied with the wing inverted, which allowed simulating the effect of lift in turbulent conditions according to the critical design case GUST C+.
The next stage of the program will be repeated tests of the fuel tanks for tightness and another ultrasonic inspection of the structure. After completing these works, the developers will continue preparing the aircraft for the next stages of testing.
