Outline Introduction l Conceptual Design - Structures - Power-Plant - Avionics l Strengths l Potential Challenges l

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

Conceptual Design

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

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

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

Avionics pod located in the front of the aircraft l 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 l

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

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