System for recovering and converting kinetic energy and potential energy as electrical energy for an aircraft

An electrical energy generator system for an aircraft, wherein the system comprises:

• a shell having the shape of a wing tip tank, wherein the shell comprises a front portion, a body, and a rear portion;
• at least one turbine housed in the front portion of the shell;
• and
• an electrical energy generator connected to the at least one turbine, wherein the electrical energy generator is configured to generate electrical energy,
• wherein the front portion of the shell includes flaps that are movable between an open position in which the at least one turbine is exposed to the air stream outside the shell, and a closed position in which the at least one turbine is masked inside the shell, and
• wherein the flaps are movably fastened between a nose of the shell and the body of the shell, wherein the flaps are hingedly fastened to the nose, the flaps being lowered inside and/or into the shell in the open position, and the flaps being held in alignment with the body of the shell in the closed position.
