Strength researches

Strength test complex of ANTONOV Company is one of the biggest in the Europe. The unique modern equipment of the complex allows performance of full-size certification strength tests of aircraft of any class from hang gliders to airplanes of “Ruslan” and “Mriya” type, products of engineering industry and to design test equipment. Dimensions of the laboratory are 100x100x35m with square of force floor to 9000m², cargo capacity of the universal portal system to 3000 tf, productivity of pump station is 7000 liters per minute.

 Strength test complex performs:

 -  static strength tests of the airplanes and their components with use of different kinds of loading (distributed, concentrated forces, excess pressure) by mean of multichannel systems (to 140 channels of loading) with research in tempo of experiment of deflected mode of construction (to 10000 indicators with the speed of poll to 1000 measurements per second);

-  resource strength tests of airplanes and their components with use of full spectrum of operational loads on complicated multilevel programmes with provision of functioning of mechanical hydraulic and electric systems of object under testing with simultaneous automated measurement of  deflected mode, bendings, registration of appearance and development of the strength cracks;

-  strength tests of constructive and technologic patterns, materials and constructions with loadings to 600 tf and frequencies to 30 Hz in order to determine standard physical characteristics, evaluation of static strength and making decisions, methods and technologies on development of constructions.

-  frequency tests of airplanes and their componrnts with record of parameters of frequencies for studying dynamic aeroelasticity in order to prevent flatter;

-  vibroacoustic tests of elements of construction under action of jet engines noise;

-  tests of seats of the crew and passengers to overload of 20g;

-  especial strength tests, for instance, dynamical on impacting of the airplane components of the aircraft with the bird with mass to 2 kg, diameter 150-400 mm and speed to 600 km/hr (with help of pneumatic gun);

-  development, design and manufacture of test stands and machines (machines of uniaxial and biaxial loading at a range from ±5 tf to ±400 tf). Completing of stands and machines includes mechanical systems, force measure devices, hydraulic systems, automatic control system and especial software;

-  production and delivery of ready designs including:

  • · multichannel automated systems of control of “Multitest-AN” strength 

experiment (8, 16, 24 channels of control in the strut); 

  • · АТИС multichannel tensiometric information-measurement systems (to 16000 channels)
