OBJECTIVE
To quantify forces and vibration at the wing with winglet.
To know the performance of wing with winglet using UTM open wind tunnel testing.
To analyse the forces produce at different aircraft’s wings with pitch angle up to 40⁰.

SCOPE
Literature review studied on the shapes, sizes and configuration of the winglets that have been used on flying aircraft.
The experiment will be executed at wind speed ranging from 10 to 20 m/s.( Until the vibration exist )
Design from Styrofoam and carrying payloads navigation as well as the existing electronic parts such as flight controller, battery and etc.

RESULTS & DISCUSSION
Without Winglet
• Pressure at lower wingspan is higher than upper.
• Lower wingspan-pressure are increase started at certain length.
• Upper wingspan-higher pressure at root and drop
With Winglet
• Pressure at lower and upper wingspan are almost same.
• High pressure started at root and drop.
