Build Name: D-2
Objective: To design an aircraft capable of carrying a payload with a dual propeller system
Type: Twin-Engine Aircraft.
Description: A twin-engine configuration was selected to generate adequate thrust to propel the aircraft carrying the payload. A rectangular planform imparted structural integrity to the motor mounts and proved advantageous for low speed applications. The high wing configuration improved stability and provided sufficient clearance to the propellers from the ground. The airfoil selected for the wing was an interpolation of two airfoils. The hybrid airfoil increased lift, smoother stall characteristics and enhanced aerodynamic efficiency. The empennage had a twin-tail configuration. The twin propellers mounted on the wings provided greater rudder authority and improved control during take-off to the fins in the propellers’ slipstream.
