In order better to cope with the dynamic forces which occur in the case of a flapping drive, the flapping surface is split into a number of relatively small and relatively short wings which are driven individually or in groups of slowly-running reversing motors. Both linear and flapping motors as well as muscle-power-operated lever drives are conceivable as reversing motors which, since they operate virtually without any transmission, exhibit a high force-transmission efficiency. Motor forces such as muscle power can be adapted well for this purpose. As a result of splitting a drive into group drives which, incidentally, are compensated with respect to pitching oscillations (as generally occur in the case of flapping wings), as a result of the arrangement into driving wings having a supporting function and control wings, both rigid supporting surfaces and conventional control surfaces under some circumstances become superfluous, as a result of which a considerably improved flight and control behaviour is obtained than in the case of the flying machines which are now normal.
