The climatic and strength testing of inboard flap and an interceptor’s section of Tu-204 is being carried out at TsAGI’s static strength laboratories, press-service of TsAGI reports. AEX.ru

"These lift devices are made of new composite materials, which require additional confirmation of strength properties under various operation conditions. In particular, after humidification coupled with mechanical loading and heating. These conditions correspond to the temperature and humidity changes, which may occur during a single flight cycle", - TsAGI noted.

The lift devices made of new composite materials are intended for new modification of Tu-204SM aircraft. As compared to their “predecessors” these devices have higher reliability and resistance to the climatic loads along with lower weight.
