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.
Claims13
An electrically powered aircraft having wings and fuselage and at least one electric motor for driving a propeller or the like for obtaining propulsion for the craft and having battery means as an electrical power source, the improvement comprising, of load bearing central wing cases for each wing, having transverse walls extending over the entire height of a wing in each instance and spaced apart in the direction of flight, each case further having profiled top and bottom plates secured to the transverse walls in liquid tight sealing manner, and for reaction and transfer of forces between the top and bottom plates, and the walls of the respective case;
- electrode plates in said central wing case which is filled with electrolytic liquid to draw electric power therefrom;
- and
- leading and trailing edge defining wing cases respectively secured to said transverse walls to complete a wing profile together with outer surfaces of the top and bottom plates.
