Airbus Helicopter EC 135 ACT/FHS

FHS

The flying helicopter simulator is a unique testbed for the development of innovative airborne systems.The original mechanical control system of this EC 135 helicopter is replaced by a full authority fly-by-wire/fly-by-light control system.

Basic essentials of the technologies, integrated in the EC 135 FHS, are the fibre optic data links in the primary control system, smart actuators and sensors, a modular system architecture and latest avionics. As a flying simulator, the EC 135 FHS is able to change its flight characteristics. As a joint development by DLR, Eurocopter Germany (ECD) and Liebherr Aerospace Lindenberg (LLI) the range of application is:

• Test bed for innovative control and guidance systems including in-flight simulation
• Integration of active side arm controller
• Test bed for pilot assistance systems
• Integration und evaluation of modern sensors and vision systems
• Evaluation of handling qualities
• Training of test pilots and flight test engineers
