Abstract:
1. An aircraft with an emission-free drive, comprising: a drive device, comprising a flapping wing device, structured and arranged to generate thrust; a lift device structured and arranged to generate lift; and a heat engine, comprising at least one flat-plate Stirling engine drivable by solar thermal radiation, structured and arranged to convert thermal energy into kinetic energy to drive the drive device, the flapping wing device including at least one flapping wing, which is pivotable transverse to a flight direction, wherein a working chamber is arranged between a wing top and a wing underside, and a displacer is arranged to divide the working chamber into a first and a second chamber region and, with movement, to displace a working gas from one of the first and second chamber region into the other of the first and second chamber region; and wherein the top of the wing forms a first side of the flat-plate Stirling engine with a first temperature and the underside of the wing forms a second side of the flat-plate Stirling engine with a second temperature, in which the second temperature is lower than the first temperature.
