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
