DLR's FHS 'Flying Helicopter Simulator'
The ACT/FHS 'Flying Helicopter Simulator' of the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) is based on a standard Eurocopter EC 135 type helicopter, which has been extensively modified for use as a research and test aircraft. The mechanical controls, for example, have been replaced by a fly-by-wire/fly-by-light (FBW/FBL) flight control system. Now the control commands are transferred by electric cables and fibre optic cables instead of control rods. The cockpit layout provides seats for a safety pilot, the test pilot and the flight test engineer. A comprehensive equipment line-up with sensors and systems for onboard data recording and processing is used to record the data from the flight tests. This data is available to users and engineers for analysis both on board and - via telemetry - on the ground.
