According to modern aviation standards, which pose stricter safety requirements, all new transport and passenger helicopters are to be equipped with a crash-resistant fuel system to protect the vehicles from the aftereffects of hard landings typical for this type of aircraft. Technodinamika has developed such a system for the first time ever in Russia and proved its performance by dropping dummy fuel tanks, as well as successfully testing other system units.
The final performance tests, held in Ulyanovsk today, included dropping a 500 kg dummy fuel tank filled with indicating liquid from a height of 15 m. The tank's shell and built-in innovative elements prevented the indicating liquid from flowing out. Under real conditions, this means that fuel will not leak out and the vehicle will avoid inflammation.
The know-how of the system is that in case of a crash, the tanks will retain their integrity, while joint breaks will take place in special elements that prevent fuel leaks. The innovative materials of the fuel tanks retain the fuel tank seal upon impact and are resistant to punctures, while fluoroplastic hoses and titanium fittings withstand high temperatures and pressure.
"This design was developed by Technodinamika under the RF Ministry of Industry and Trade program, and we are seeing real results of the Holding's work," says Andrei Boginsky, Deputy Minister of Industry and Trade. "It is important for Russian helicopters to be equipped with the new system because it will substantially enhance their reliability and safety, which will enhance their competitive power on Russian and worldwide markets as well."
"Successful completion of the extreme-conditions performance tests is a great success. Such systems have never before been developed in Russia, and there are just a few counterparts in the world," notes Maxim Kuzyuk, CEO of Technodinamika. "In 2016–2017, after optimizing the weight and performance for a specific helicopter, we will carry out complex reliability testing of the system. After that we will be able to certify our design in line with the international standards and offer it to Russian and international helicopter equipment manufacturers."
