Abstract

A differential multipropeller system (100, 200, 300, 400, 600, 700) comprises a drive shaft (103, 203, 303, 403, 605, 702) as well as a first propeller (101, 601, 707) and a second propeller (102, 602, 708). The propellers are arranged concentrically in succession and so that, while the drive shaft turns around, it rotates the first propeller in an opposite direction than the second propeller. The drive shaft is concentric with the two propellers and extends through both of them.
