Abstract - This project explores the design and development of an eight-seat short-range business jet, aiming to optimize performance, passenger comfort, and operational efficiency for regional travel. With a targeted range of 2,500 nautical miles, the proposed aircraft is intended to facilitate quick and convenient transportation between major urban centers. The design features a modern seating arrangement that ensures passenger comfort and privacy, along with advanced amenities that enhance the in-flight experience. The aircraft will be powered by twin turbofan engines, allowing it to cruise at speeds of approximately Mach 0.8. In this paper a business jet aircraft is designed to carry 8 passengers and with service ceiling of 45,000 ft Preliminary analyses confirm that this configuration strikes an effective balance between performance and fuel efficiency. The airframe will utilize advanced composite materials to reduce weight while enhancing structural integrity and aerodynamic properties, thereby improving overall efficiency.
