Advanced Sensor and Packaging Technologies for Intelligent Adaptive Engine Controls (Preprint).

摘要

The development of a pressure/temperature multi-sensor based on a combination of micro-electromechanical systems (MEMS) sensor technology, novel ceramic materials, high-temperature electronics, and advanced harsh-environment electronics packaging is discussed. The pressure/temperature multi-sensor enables unprecedented monitoring of propulsion, energy generation, and industrial systems. A multi-sensor approach will reduce control system weight and wiring complexity, design time, and cost. Multi-sensor control strategies do better than the single-sensor strategy on the basis of both to raise the accuracy and fault tolerance ability effectively. The resulting sensors and packaging can be manufactured at low cost and operate in corrosive environments, while measuring temperatures up to 2,552 deg. F (1,400 deg. C) with simultaneous pressure measurements up to 1,000 psi. The combination of a high-temperature, high-pressure-ratio compressor system, and adaptive engine technologies enables high thrust and efficiency.
