1 VTOL PROBLEM IDENTIFICATION
• Extra aerodynamic drag results in additional burden to the pushers • Extra unnecessary weight coming from the VTOL motors itself Capable to take-off, hover • The overlapped thrust during the and land vertically transition flight mode
2 OBJECTIVES SCOPES
Conduct wing deflection test to Carry out flight test A total weight 4 VTOL motors not more than find effect of VTOL to determine the and 1 pusher 4kg (including motors on wing highest power motor vertical deflection consumption payload) during take-off
Carry out Consists of 2 sets of Analysis cover flight test to propulsion from structural, determine the system with propulsion and suitable PID battery as control system controller power source

11 STRUCTURAL ANALYSIS VTOL motors added to the wing
During taking off, a point force Objective: To find the effect exists of VTOL motors on wing 4L = W, assume lift needs to be vertical deflection 1.5>W to lift the UAV
State/solve analytically to find SFD and BMD
Wing deflection test
12 13 DEFLECTION Attach wing upside down to TEST bracket
Fix the bracket to the rig by using screws
Place dial gauge at four different locations
Slowly increase the amount of weight placed on the wing
Read the dial gauge for deflection data
