E-SEMA · Development of Electric Smart Actuator for gas turbine engines

The E-SEMA project will design, manufacture and test an innovative concept of light, reliable and smart electrical actuator for an inlet guide vane or stator vane application of gas turbine engines that will be capable of interfacing and connecting to the engine control unit in a plug-and-play manner. This innovative concept of smart electrical actuator will be based on a multi-disciplinary approach that will consider mechanisms, the control electronic, the control software and the power supply in an integrated way, as will be shown in the following subchapters. The main topics that are going to be developed in this proposal are related to the temperature levels and environmental conditions (combustion gas, oxidation) that are the normal aero engine working conditions.In this respect, the present consortium is currently working in a similar application inside JTI Clean Sky (HP-SMART-EMA / Development of high power density electrical actuators / HP-SMART-EMA / Topic addressed: JTI-CS-2009-1-SAGE-05-006) under contract CS-GA-2009-255819. The scope of this project is the development of high power density electrical actuators with Smart electrical interfaces in severe environment:• The WP 5.2.5 of SAGE5 Demonstration Project dedicated to the development of an innovative control system, aims also at developing and testing Smart electrical actuators for turbine engine control systems• The target is to have a light, reliable and “easy to interface to a control unit” electrical actuatorAll the experience and lessons learnt in the ongoing HP-SMART-EMA project will be applied and considered in the present proposal: motor, high temperature, benchmarking performed for sensors, motors, gear, brakes, ..., lubrication, redundacy for increased reliability, ...3 or 4 actuators are foreseen to be manufactured inside the proposal:o One unit for MTUo One/Two for testing validationo One unit as spare""
