Abstract— This research paper presents the design of a multi-mode fighter jet that integrates advanced aerodynamics, large wing surface areas, and a unique propulsion system. The jet is equipped with a cold jet engine mounted on the sides, a tilting vertical tail, and a rotating engine section that allows for vertical as well as horizontal take-off and landing (VTOL/HTOL) capabilities. This design focuses on efficiency, agility, and adaptability, making it a versatile solution for modern aerial combat and operations.
