"The ARMLIGhT project will design, manufacture, tune and validate an innovative and smart Electro-Mechanical Actuator for the study and validation of a future complete all-electric landing gear actuation system. ARMLIGhT actuator will be based on a modular and efficient approach that will integrate easily exchangeable electric and mechanical components with sensors and control strategies that will allow automatic and autonomous safety control.The ARMLIGhT Electro-Mechanical Actuator will include its dedicated Electronic Control Unit, a Built In Test equipment to detect potential failures and a disable device to guarantee compatibility with emergency actuation. Different configurations will be studied and evaluated to determine the optimum system architecture from a technical point of view. Volume, mass, electrical consumption, power to mass ratio, reliability, durability and safety are concepts that will drive the development.The ARMLIGhT system will be tested and validated at several stages: Virtual validation at model level and finally actual experimental validations of the complete system through both on-ground and in-flight test campaigns. These sequential and complementary validations will assure thus a reliable, safe and efficient performance of the prototype and will provide data for a deep concept evaluation.For this validation purpose, the ARMLIGhT project will also design, manufacture and tune a Test Rig for ARMLIGhT Electro-Mechanical Actuator validation. ARMLIGhT Test Rig will allow installation both in Copper Bird® and in the ATR (Avions de Transport Regional) passenger cabin. The test bench will also include its own control system, inertia load simulation of the Main Landing Gear involved weight and counter-load actuator with its hydraulic and electric power supply systems."
