The U.S. Army Aviation Applied Technology Directorate (AATD) launched the Autonomous Sustainment Technologies for Rotorcraft Operations (ASTRO) program to demonstrate technologies to more efficiently design and maintain their current and future vertical lift aircraft fleet. The critical gearbox components to improve were identified as the planetary gears and bearings.

Boeing selected Sentient Science to provide prognostic life prediction models for the planetary gearbox and its critical components. In design and testing, these models will be used by Boeing to give engineers much better knowledge and insight into the planetary gearbox’s reliability and performance under multiple sensitivity tests, often under multi-variable conditions. By interfacing these models with their actual operating conditions, Sentient can suggest life extension options, such as surface treatment options, duty cycle options, and remanufacturing overhaul options – and then simulate the performance
improvement of those options for the fleet.

For operations and maintenance, these DigitalClone models will then be interfaced into Boeing’s existing on and off-board processors (HUMS) for autonomous monitoring. With DigitalClone prognostic models and live operational data, the U.S. Army will be able to predict and control their helicopter’s gearbox life and ensure missions are completed safely. By interfacing the models through the Internet to improve the life of fielded assets, we are supporting what GE and others now call the Industrial Internet.
