Title:
AIRCRAFT VEHICULAR PROPULSION SYSTEM MONITORING DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO2004094954
Kind Code:
A3
Abstract:
Methods and systems for monitoring rotating shafts (28) and couplings (30) in an aircraft vehicle propulsion system (22) is described. The measurement system/method provides for accurate and precise monitoring of a rotating shaft flexible coupling in a fixed wing aircraft vehicle propulsion system (22). The measurement system/method provides for a high reliability short take off vertical landing fixed wing aircraft in which the vehicle's dynamically rotating drive shaft system (28) and couplings (30) are monitored in real time. The vehicular shaft coupling misalignment measuring system utilizes multiple positional sensors (40) to provide highly reliable and precise determination of the dynamic characteristics of the rotating sensor target components of the propulsion system drive shaft (28). The relative position of the sensors (40) is rigidly fixed externally from the rotating targets with a structural frame. The misalignment measuring system provides a misalignment measurement of the propulsion system drive shaft flexible coupling which relates to a critical performance of rotating shaft (28) coupling in the operating of an aircraft vehicle (20). The method/system provides for monitoring a rotating drive shaft system and dynamically measuring a rotating drive shaft coupling in a fixed wing aircraft propulsion system (22).
