Obninsk Research and Production Enterprise Technologiya named after A.G. Romashin has developed a new radar-transparent radome production technology for helicopter navigation systems. Thanks to the use of advanced quartz fabric composites, the airborne radar performance was improved by more than 10%.
Airborne radars on civil helicopters are necessary for navigation and prevention of collisions with ground and aerial objects. They are protected against external impacts by radomes, which shall have an aerodynamic configuration, shall be robust and radar-transparent. The radome designed by ORPE Technologiya is made from a quartz fabric composite. Therefore, it can better pass signals and consequently improves radar performance on helicopters and other low-speed aircraft.
“The use of advanced materials in aircraft equipment facilitates significant performance improvement. When working on radar-transparent radome for airborne radars, Technologiya professionals used their experience in developing similar systems for high-speed aircraft. As a result, it was possible to improve the equipment performance by 10% and to reliably protect it against external impacts. We are now working out the opportunity to introduce this development into manufacturing of new Russian helicopters,” said Andrey Silkin, General Director of ORPE Technologiya.
The radome was tested on a special stand with an active airborne radar. The tests have shown that it provides an electromagnetic wave transmission coefficient of at least 90-92%, which is on average 10% higher than required by international standards for such products. The development is protected under the patent law.
