Previously the 1st generation of HALE UAV ITB used balsa wood for most of its structure. M E C H A N IC. This paper conducted a study on designing the 2 nd generation of HALE UAV ITB which used composite materials in order to substitute balsa wood at some critical parts of the wings structure.
This paper is a continuation of the first paper and presents buckling and flutters analysis. Design manufacturing and testing of a HALE-UAV structural demonstrator. Design of High Altitude Long Endurance UAV.
The MALE UAV is defined as an aircraft that has no manned crew on board flying at altitudes between 10 000 and 30 000 feet or 3048 m and 9144 m for missions that last ten hours or longer. The wing structure is broken down into non-spar elements and spars. SMALL UNMANNED FIXED-WING AIRCRAFT DESIGN.
To design an automatic HALE-UAV that is capable of remaining aloft for very long periods of time about 69 months thanks to a solar-powered and fuel cell system. The wing was made of a carbonepoxy laminate with orthotropic arrangement 0045. Close Log In.
The latest Lim et al 9 optimized wing design of Solar-HALE aircraft by considering interaction between aerodynamics and structures. To gain a complete understanding of the feasibility of a near-term aerodynamic HALE concept especially concerning low-Reynolds profiles and propellers. The composite material accounts for 45 of the weight of the X-45A structure.
Based on the results the wing composite structure of the maritime surveillance UAV is safe because it has factor of safety of 166 for load factor 38 and 335 for load factor -152 based on Tsai-Wu failure criterion. The analysis is conducted with load factor of 38 and -152 which represent maximum and minimum load factor. Multi-Objective Optimization of the Composite Wing Box of Solar Powered Hale Uav.
