Crash Load Distribution Structure of Fuselage

A crash load distribution structure of a fuselage may include a front fuselage frame surrounding a front surface of the fuselage, a crash unit disposed at the front end of the front fuselage frame, an extension frame coupled to the crash unit and extending to a floor frame, and a battery unit disposed under the floor frame and coupled to a portion of the floor frame constituting the floor frame. The battery unit may be selectively separable from the portion of the floor frame, e.g., if a crash load is transmitted from the extension frame.
