THE AIRBORNE-SYSTEM critical-design review for the GEC-Marconi Defence Systems-developed Integrated Health & Usage Monitoring System (IHUMS II) has been completed successfully.
The IHUMS II is scheduled for certification on the Sikorsky S-76C+ this year. The system uses high-speed computer processing to diagnosis engine, transmission and rotor-system health.
The company says that the first version of the system has so far accumulated almost 150,000 operating hours on seven different types, "...contributing to significant safety and maintenance benefits for operators of Sikorsky, Eurocopter and Bell twin-turbine helicopters".
