PROJECT DESCRIPTION SAE International holds annual Collegiate Aero Design competition Universities from around the world showcase aircraft designs of various sizes to convey use of resources and efficient design Micro class required to design a radio controlled aircraft which carries the highest payload fraction possible, while maintaining lowest empty weight possible. Judges score each design based on written report, oral presentation, flight results. Figure 1: Cedarville SAE Aero Design Team[1] September 27, 2016 | SAE Aero Micro Class | Team 18 | Mohammad 2
DESIGNS CONSIDERED Concept Wing Airfoil Material Motor Propeller Body 1 High Normal/ Flat bottom Normal Foam Single Brushless 2 Prop Carbon Fiber 2 Flaps Foam Twin Brushless Single Brushless 2 Prop Square 3 Expandable Straight Flat bottom Straight Flat Bottom Clark Y-14 Monokote 2 Prop Carbon Fiber 4 Delta Wing Balsa Wood Twin Brushless 3 Prop Square 5 Biplane Foam Single Brushless 3 Prop Carbon Fiber September 27, 2016 | SAE Aero Micro Class | Team 18 | Michael 3
DESIGNS CONSIDERED Concept Advantages Disadvantages 1 -Greater Lift/ Stability Lightest -Greater Lift when deployed -Flexible -Low Power -Must be deployed for extra lift -Square body not aerodynamic -Can collapse -Possibly too light -May not fit size constraint -Heavy -Greater drag -Heavy 2 3 -Fits size constraint 4 -High speed -Twin motors provide more thrust -Stable -High lift 5 September 27, 2016 | SAE Aero Micro Class | Team 18 | Yaqoub 4
DESIGN SELECTION Delta Wing and Biplane eliminated based on disadvantages Twin Brushless Motor and square body are too heavy and create more drag Monokote viable, but creates more weight Flaps control angle of attack. Allows for optimal lift. High wing creates more lift due to placement and glides well if motor fails Carbon fiber body is lighter than the square body Foam is light and durable Final Selection: Concept 1 High Wing/Flaps Flat Bottom Airfoil Foam Material Single Brushless Motor 2 Blade Propeller Carbon Fiber Body September 27, 2016 | SAE Aero Micro Class | Team 18 | John 5
