Unmanned aircraft i.e. unmanned helicopter, for e.g. vertical take off and landing, has shaft-power turbine driving generator to generate current that is fed to motor and/or batteries, where motor is operated with current from batteries
摘要
<p>The aircraft has a drive designed as a hybrid-drive. A shaft-power turbine (20) drives a generator (30) for generation of current that is fed to an electric motor (42) and/or back-up batteries (40), where the electric motor functions as a primary drive. The current from the shaft-power turbine is rectified with a rectifier (32). The hybrid-drive is controlled in such a manner that the electric motor is operated with current from the back-up batteries during a case of failure of the shaft-power turbine.</p>
