Aircraft design is a complex process that involves the creation and development of aircraft, focusing on their performance, safety, and efficiency. Engineers consider various factors such as aerodynamics, materials, and propulsion systems to ensure that the aircraft meets specific requirements and regulations. The design process typically includes conceptual design, preliminary design, and detailed design phases. Each phase involves extensive calculations, simulations, and testing to optimize the aircraft's structure and systems. Successful aircraft design results in vehicles that can safely transport passengers and cargo while minimizing environmental impact.
