RÉSUMÉ

The computational analysis of the efficiency of a propeller in a viscous wake is performed. A simplified model of an airship with a stern-mounted propeller is considered as an example. Velocity field near the airship, pressure distribution, and shear stresses on the airship surface are computed for the cases of an operated propeller and a turned-off propeller. Analysis of forces acting on the airship and on the propeller is performed for the propeller mounted in an airship stern in a viscous wake and for the propeller located out of the airship interaction zone. The power required for the cruise flight is shown to be approximately 7.5% less in the first case.
