PAV Technologies in Ground-Based and In-Flight Simulation

摘要: The ACT/FHS ‘Active Control Technology/Flying Helicopter Simulator'is based on a standard Eurocopter EC135 type helicopter. It is a modern, twin engine, light helicopter with a bearingless main rotor and fan-in-fin tail rotor. The basic aircraft has been extensively modified for use as a research and test aircraft. The main difference is the implemented fly-by-wire/fly-by-light control system that allowed for the integration of a very flexible experimental system. A multitude of scientific investigations, such as handling qualities investigations, pilot assistance or in-flight simulation of other aircraft can be covered by the Flying Helicopter Simulator.It is evident that an in-flight simulator cannot represent an aircraft with faster dynamic responses than those of the basic aircraft. Therefore, a fundamental requirement for airborne simulation is a high dynamic response capability of the basic vehicle. The EC135 is a rotorcraft with very high agility and thus has the potential for the simulation of a wide variety of existing and future helicopters. Before an actual Personal Aerial Vehicle (PAV) is ever built, the ACT/FHS is used to simulate PAV flight characteristics in flight. The experimental system supresses the original EC135 dynamics and lets the ACT/FHS behave like an easy-to-fly PAV.
