HELICOPTER RADAR ANTENNA-FEEDER ASSEMBLY Russian patent published in 2007 - IPC H01Q1/28 

Abstract RU 2291525 C2

FIELD: radar antenna-feeder assemblies for helicopters.

SUBSTANCE: proposed radar antenna-feeder assembly designed for trouble-free operation under variable- and vibratory-load conditions due to enhanced strength incorporated in its mechanical design and improved aerodynamic properties of elongated antenna array and feeder circuit has its receiving-radiating components forming flat elongated antenna array and high-frequency feeder circuit physically integrated with functional units; antenna array case accommodates its suspension unit for turning it by means of helicopter-mounted drive from horizontal transport position under helicopter fuselage to vertical working position and vice versa. Antenna array modules function as its stiffness ribs. Provision is made for easy disconnection of antenna array from helicopter under emergency conditions.

EFFECT: enhanced operating reliability, optimized mass and size, improved aerodynamic properties of antenna array.
