The vibrational qualification activities of the landing gear system of the RACER Compound Helicopter, a demonstrator developed by Airbus Helicopters as part of the Clean Sky 2 program dedicated to Fast Rotorcraft, have been successfully concluded at the Space Qualification Laboratory of CIRA Italian Aerospace Research Center – Capua (NA) .
The tests carried out, which are part of the final activities of the ANGELA project – aimed precisely at the design, construction and qualification both on the ground and in the air, of the RACER landing gears – have demonstrated full compliance with the requirements dictated by international standards (Sec. 8 “Vibration” of the DO160G standard “Environmental Conditions and Test Procedures for Airborne Equipment” “), leading to the vibrational qualification of the entire system, consisting of the front landing gear (Nose Landing Gear), the main landing gears (Main Landing Gears) and their actuators (Drag Brace Actuator-DBA, Side Brace Actuators – SBA). The actuators were tested in both extended and retracted configurations, in order to simulate all the operating conditions of the truck system.
As part of the Angela project, CIRA coordinates a consortium which includes the Magnaghi group, the design authority that developed the trucks on Airbus specifications, and companies such as M&S, Aviatest and TSD Space which, together with CIRA, supported design, analysis, qualification and innovation activities. The prototypes of the landing gears intended for flight have already been delivered to Airbus Helicopters and installed on the final demonstrator.
