Andrey Andreyevich Kargapolcev  Head of Division 

FULL SCALE AIRFRAMES STATIC AND FATIGUE TESTS

Full scale testing of airframes and its components with automated loading control, continuous test monitoring of airframe loads and states using the methods of non-destructive testing and strain measuring.

Virtual test simulation with finite element models designing, and drawing-up recommendations on improvement of the airframes under testing.

Formation of pneumatic systems aimed to simulate operating loads during aviation equipment and engineering tests, production of test-benches for hydraulic equipment, and hydraulic equipment repair.

Development of multichannel automated load control systems.

NUMERIC STUDIES OF AIRFRAME STATIC AND FATIGUE STRENGTH, AND STABILITY

Finite element analysis of local strength and calculation assesment jf full-scale airframe elements fatigue life.

Solving problems of elastic-plastic strain and skin creep under unconstrained motion.

Finite element analysis of significant nonlinear deformation and static aeroelasticity of flexible structures.

RESEARCHES OF MATERIALS AND AIRFRAME SAMPLES, AND THEIR FRACTURE KINETICS DURING FULL-SCALE TESTS AND OPERATION

Metallographic studies of material structure with the aim to determine its affect to the fracture processes.

Quantitative analysis of metallography and fractography results using the digital image processing complex.

Standard static and cyclic tensile, compression, and bending tests of samples at normal and high temperature.

Static and cyclic crack resistance test of material samples.

Creep rupture strength tests.

Corrosion resistance testing under load.

Experimental evaluation and improvement of design and technology concepts with consideration of operational factors.

Material samples and airframe elements tests in terms simulating factual operational impacts — load spectra, temperature conditions, and environmental impacts.

CONVERSION ACTIVITIES

Nondestructive test of general industrial objects (including die-cast parts of railway carriages, bridges and rails, boilers and pipelines) using acoustic emission systems.

Testing on static strength and fatigue life of industrial objects (structural beams, flooring, components of stairs, bridges, railway vehicles elements, mining, rigging, lifting and transporting equipment, and pipelines) with the overall parameters less than parameters of the static testing laboratory (80 × 80 × 35 m) and the load per one point less than 500 tons.
