Turbofan engine demonstration of sensor failure detection
TL;DR: In this article, the results of a full-scale engine demonstration of a sensor failure detection algorithm are presented, which detects, isolates, and accommodates sensor failures using analytical redundancy.
Full-scale engine demonstration of an advanced sensor failure detection, isolation and accommodation algorithm: Preliminary results
TL;DR: In this article, an advanced detection, isolation, and accommodation (ADIA) program is proposed to improve the overall demonstrated reliability of digital electronic control systems for turbine engines using analytical redundancy.
Summary of investigations of engine response to distorted inlet conditions
TL;DR: A survey of experimental and analytical experience of the NASA Lewis Research Center in engine response to inlet temperature and pressure distortions is presented in this article, which includes a description of the hardware and techniques employed, and a summary of the highlights of experimental investigations and analytical modeling.
Measurement Uncertainty for the Uniform Engine Testing Program Conducted at NASA Lewis Research Center
TL;DR: In this article, an uncertainty analysis was conducted to determine the bias and precision errors and total uncertainty of measured turbojet engine performance parameters, including engine inlet airflow, engine net thrust, and engine specific fuel consumption measured at high rotor speed of 8875 rpm.
Proceedings ArticleDOI
Full-scale engine demonstration of an advanced sensor failure detection isolation, and accommodation algorithm - Preliminary results
TL;DR: Preliminary results of a full scale engine demonstration of the ADIA algorithm are presented, with minimum detectable levels of sensor failures for an F100 turbofan engine control system determined and compared to those obtained during a previous evaluation.
