Abstract

A Litton LN-200 fiber optic gyro IMU has been successfully adapted to provide flight control and AHRS data messages via a dual rate AS-1773A fiber optic interface to the FLASH demonstration system. To provide a rugged, reliable demonstration unit, the production LN-200 IMU is mounted in an adaptive housing along with the circuitry to convert the LN-200 RS-485 SDLC electrical interface to the FLASH 1773A fiber optic interface. A dc/dc converter is also incorporated to provide the additional voltages required for LN-200 and conversion circuitry operation. Software modifications to generate the requisite output data from the LN-200 IMU incremental angle and velocity data were developed for the VFCS program. Following integration, the FLASH IMU completed demonstration testing at Litton and was delivered to McDonnell Douglas in February 1996. There, the unit successfully completed laboratory flight control testing in the integrated fiber optic configuration.
