ABSTRACT
The aircraft design process starts with the feasibility phase-the development of an idea for the project. This phase is heavily dependent on marketing requirements to identify the concept and specic features. Sincere attention and efforts are then applied to the concept and denition phase to minimize overall design costs and development risks. The aircraft design process integrates input from various disciplines including aerodynamics, payload, structure, materials and process, ight control, research and technology, etc. The aerodynamic denition of the aircraft will determine the least amount of air drag to make the aircraft more fuel efcient. Improved materials will also help to reduce the total weight of the aircraft, and improve fuel efciency as well.
