Concept Design Generation

Based on the objectives, the team came up with 3 general designs: single-wing plane, bi-wing plane and flying-wing plane.

The team sketched and modeled the basic concepts.  The pros and cons for each concept were also listed and considered in the selection of the final design.  As an aid, the team prepared a Concept Screening Matrix that compared the concept designs among each other.

From the designs and the Concept Screening Matrix, the following were observed:

  • Flying-wing concept will prove challenging in terms of control and stability because of the lack of a tail section
  • The drag created by the bi-wing deign may prove to be a critical design flaw, which will affect the size of the engines and fuselage to be used
  • Combination of flying-wing and single-wing will be the best design
  • Concept Screening Matrix shows that the single-wing design will have the least amount of risk and be the most reliable design

Single-Wing Concept Design

                     

Pros: Low Cost, Light Weight, Stable Turning, Large Payload to Weight Ratio, High Lift, Low Drag

Neutral: Take-off and Landing Distance, Durability, Assembly


 Bi-Wing Concept Design

        

 Pros: Light Weight, Take-off and Landing, High Payload to Weight Ratio, High Lift

 Neutral: Cost, Turning, Durability, Stability,

 Cons: Difficult Assembly, High Drag


Flying-Wing Concept Design

                          

Pros: High Lift, Low Drag, High Stability, Large Wing Area, Easy Assembly

Cons: Unstable in High Winds, Tail Stabilizers are Less Maneuverable

 Bent Flying-Wing Concept Design

       

 Pros: Low Drag, High Stability, High Lift, Low Weight, Easy Assembly, High Wing Area

 Cons: Unproven Design, No Payload Area, Unstable in Longitudinal Direction
