Re-design the aging commercial aircraft series -Boeing 737s.
Re-design the aging commercial aircraft series -Boeing 737s.
We named our concept aircraft as Odyssey.
We named our concept aircraft as Odyssey.
We implemented the design procedure in the book, Airplane design, Jan Roskam. The design was separated into two parts. Part I defined the specifications of the aircraft. And Part II determined the size and detail configuration of each aircraft component, including fuselage, cockpit, wing, high lift device, empennage, and landing gear.

Weight, Wing Loading, and Thrust to weight ratio
Weight, Wing Loading, and Thrust to weight ratio
Weight and fuel consumption were the crucial parameters in aviation industry. At this stage, we estimated aircraft weight during the mission, sized the wing geometry, and selected the jet engine that fitted to our needs.

Fuselage
Fuselage
To design the fuselage, we gathered the data from other commercial aircraft for comparison, the information of cargo container for fuselage cross section compatibility and the regulation from FAA for emergency and safety consideration.

Cockpit
Cockpit
Based on the reference data of the adult size, we arranged our cockpit in the prospect of maximizing pilots' field of vision and minimizing their inconvenience to reach any control panel.

Wing
Wing
Wing configuration was determined by aerodynamics and fuel volume requirement. This wing featured aerodynamic twist so that two airfoil were selected.

High Lift Device
High Lift Device
During aircraft take-off and landing, flaps or slats are extracted to generate more lift. We combined previous lift coefficient of take-off, landing data, and the configuration of the wing platform to design flaps that could generate adequate amount of additional lift we require.

Empennage
Empennage
Empennage provided stability and control in lateral (pitch) and vertical (yaw) axis. We sized the empennage by the common Volume method.

Landing Gear
Landing Gear
Landing gear supported the whole weight of airplane and balanced the airplane attitude during takeoff and landing. Our main purposes were to find a feasible position and to design a great structure for landing gear.

CG Estimation
CG Estimation
To finalize the layout of the whole aircraft, we did C.G. estimation during the mission to arrange the exact position of each component.
