Title: Electrically powered aircraft

Abstract: The wings of an electromotorically drive aircraft have span wise extending central wing cases whose interior serves as battery cells. Load bearing transverse walls take up bending stresses reacted into such walls by tops and bottoms of such central wing case. These tops and bottoms may constitute the electrodes of the battery. Leading and trailing edge-profile completing wing cases are secured, possibly releasibly secured, to the transverse walls of the central wing case.
