DESIGN & FLIGHT TEST RESULT OF A SMALL SCALE HYBRID VTOL UAV

Abstract

Installing a quadcopter in H-configuration onto the wings is one of the ways to introduce vertical flight to a fixed wing UAV. Forward flight is attained by tilting the motors to create forward thrust. This paper discusses the design considerations for the Hybrid VTOL UAV and presents the results from flight tests. The motors are electric and powered by Lithium-Polymer batteries. XFLR5 is used to calculate the aerodynamics variables of the design. Drag and flight endurance is calculated empirically and compared against the real values obtained from flight tests.
