1. AAE 451 – Fall 2003 Ares Team Mir Rashiduzzaman Alethea Tan Kai-Hui Leong Darwin Lisan Jung Hyun Ahn John Ko

2. Outline • Introduction • Conceptual Design - Structures - Power-Plant - Avionics • Strengths • Potential Challenges

3. Main Goals • To meet the mission constraints • To satisfy customers’ needs • To keep cost down • To increase performance

4. Conceptual Design

5. Structures • Main frame – square chamfered fuselage with tapered wing attached • Wing installed on the top of the fuselage • Tail connected to the wing via two horizontal tail booms • Two vertical rudders attached to the elevator attachment

6. Structures • Pod and Air-data boom situated in the front of the aircraft • Tricycle landing gear

7. Power-Plant • Pusher type internal combustion engine • Fuel tank placed on the C.G of the aircraft • Situated at the end of the fuselage, behind the wing

8. Avionics • Avionics pod located in the front of the aircraft • Seven servos - Three on the tail for elevator and rudders - Two on the aft fuselage section for ailerons - Two on the fuselage for engine throttle and nose gear

9. Strengths • Simpler Design – low manufacturing cost • Thicker Airfoil – increase wing stiffness, increase favorable pressure gradient giving better performance at high AOA • Tapered wing – reduce wing weight, better stalling characteristics • Location of wing, pod and air-data boom • High landing gear

10. Potential Challenges • Tapered wing – harder to manufacture • Torsional stresses on tail booms • Hybrid Structure, joint interface • Composites – labor intensive
