The concept of a "More Electric Aircraft" (MEA) leads, among other actions, to the substitution of hydraulic-based actuators for Electro-Mechanical Actuators (EMA). Removal of the engine hydraulic pumps requires fully-operative electrical power actuators and mastery of the flight control architecture. However, unexpected faults and lack of safety hinder the massive use of EMAs in flight...
This paper shows a Fault Anticipation Software System (FASS) architecture, for diagnosis and prognosis purposes, in order to be implemented in a FASS unit, that nowadays, is a necessary tool to diagnose aircraft Electro Mechanical Actuators which are been implemented in order to face up to ldquoMore Electric Aircraftrdquo (MEA) technologies. This work shows the requirements in a FAS system, and a...
The civil aviation industry has expanded considerably in aircraft systems in the 100 years of its life. Although there are major developments in all aspects of flight, the fastest growing trend is for More electric aircraft (MEA) and low emissions; consequently, the complexity of electrical and electronic systems is increasing. It is therefore highly desirable to provide a simple, reliable, and sustainable...
