US: Northrop Grumman has been selected by AgustaWestland to provide flight-critical inertial instruments on the new AW609 TiltRotor aircraft undergoing civil certification through the Federal Aviation Administration. "This suite of combined equipment provides critical flight control and navigation data to help the aircraft achieve required availability, precision and the highest levels of integrity. Our products enhance precision navigation operations, improve safety margins, save weight and volume, and provide attractive commercial advantages,” said Eckehardt Keip, Managing Director, Northrop Grumman LITEF.
The LCR-110 features a high-performance, fibre-optic gyro-based inertial measurement unit and an advanced micro-electromechanical system (MEMS) triad accelerometer. The system offers hybrid navigation via GNSS data, in addition to aircraft autonomous integrity monitoring for GPS signal integration and integrity checks. These features are essential for precise Required Navigation Performance (RNP) flight operations. The LCR-110 evolved from the successful, longstanding LCR-100 product family that has been selected for numerous rotorcraft and fixed-wing platforms. The LCR-300A is being introduced after several years of independent research and development. The system's MEMS gyro provides advanced attitude heading reference system performance in combination with a magnetic sensing unit. It also features directional gyro mode, which minimises magnetic compass errors.
