Abstract: The present invention relates to an aircraft, comprising a fuselage, at least one pair of wings and a battery system for providing power to electrical systems of the aircraft, wherein the battery system comprises at least one battery pack, each battery pack comprises a number of individual battery modules, which are directly or indirectly coupled to one another, and the at least one battery pack is disposed between an inner structural wall defining an interior space of the fuselage and an outer fairing wall of the fuselage. The fuselage is provided with a rack mounting mechanism comprising a number of mounting brackets, each for exchangeably mounting one of the battery modules to the aircraft, and each of the battery packs is a virtual battery pack, which is obtained by electrically connecting a predetermined number of the battery modules.

Abstract: A method for manufacturing a vehicle frame is disclosed. An upper body of the vehicle frame is formed, the upper body configured to be joined with an underbody of the vehicle frame at a first component of the upper body. The underbody of the vehicle frame is formed, the underbody configured to be joined with the upper body at a first component of the underbody. After forming the upper body and the underbody, a point on the upper body is aligned with a desired position for the point, independent of an alignment between the first component of the upper body and the first component of the underbody. After aligning the point on the upper body with the desired position for the point, the first component of the upper body is joined to the first component of the underbody.
