The wing structure is modeled and analyzed using finite element to assess its integrity.

. High-altitude long endurance unmanned aerial vehicles HALE-UAV flying in the stratosphere can provide a useful platform for sensors to support a range of military and civilian surveillance tasks. Composite structures are the most popular technology employed in small UAV structures. Driven UAVs KARI has designed EAV-3 a solar-powered HALE UAV.

Indeed the low on-board power of the latter involve a high level of aero-dynamic and structural performance. In addition the structural stiffness for the high aspect ratio wing is another critical design requirement because the UAV has to keep the minimum clearance between wing tip and ground when the UAV is being towed. 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. Güventürk Mini UAV which is. For the 2nd generation HALE UAV ITB is designed having 16 m wing span with 04 m chord length.

The latest Lim et al 9 optimized wing design of Solar-HALE aircraft by considering interaction between aerodynamics and structures. The wing is built modular with the length of each segment is 2 m. HALE-UAVs are characterized by a high aspect ratio wing resulting in very flexible airframe.

The real physical structure of aircraft. The concept of load bearing types of the skin are compared in the analysis. For above design requirements the wing structure of the UAV has been.

Every wing segment will be joined using a glass-fiber joiner at the front spar. Download Citation HALE UAV Composite Wing Structure Design HALE High Altitude Long Endurance UAVs are aircraft systems for surveillance and reconnaissance for over 25 hours. EAV-3 weighs 53kg the structure weight is 22kg and features a flexible wing of 195m in span with the aspect ratio of 174.

The wing was modeled as a beam structure. The first paper deals only with the static strength analysis. For the 2nd generation HALE UAV ITB is designed having 16 m wing span with 04 m chord length.

Fuselage Shell and Internal Structure with Shell Wing Landing Analysis. This paper conducted a study on designing the 2nd generation of HALE UAV ITB which used composite materials in order to substitute balsa wood at some critical parts of the wings structure. Manuscript received April 9 2016.

The structural design of the UAV composite wing regarding buckling analysis is more effective when the laminates are stacked up with high percent of - 45 degrees plies and the -. Up to 10 cash back In general the main wing of a HALE UAV is composed of composite spars ribs leading edge trailing edge and thin plastic covering film to reduce structural weight 3 4 5. The very flexible wing need to be designed so it can satisfy the deformation and strength criteria.

The wing was made of a carbonepoxy laminate with orthotropic arrangement 0045. In this research the wing structure of initial version of HALE UAV is designed using carbon composite material. Medium Altitude Long Endurance MALE e High Altitude Long Endurance HALE.

Manufacturingisperformedatthe compositelaboratoryfounded in theDepartment ofAerospace Engineering and with hand lay-up and vacuum bagging method at room temperature the wing is produced. Rigidity of a HALE aircraft wing structure. A preliminary composite laminate structural design procedure is described which uses a NASTRAN-based Finite Element Analysis FEA and the Hierarchical Evolutionary Engineering Design System HEEDS MDO software to define a locus of acceptable optimized wing box design definitions.

The latest Lim et al 9 optimized wing design of Solar-HALE aircraft by considering interaction between aerodynamics and structures. UAV wing material characterization of the composites used in the UAV wing and prelimi-nary structural analysis of the UAV wing. To gain a complete understanding of the feasibility of a near-term aerodynamic HALE concept especially concerning low-Reynolds profiles and propellers.

Design manufacturing and testing of a HALE-UAV structural demonstrator. Close Log In. The structural weight of HALE UAV is one of the most critical design requirements.

The scaled wing structure can be divided into a 112 m long constant chord inner-wing and two 657 m long tapered chord outer wings one for each side. Designing the main wing and empennage of the EAV-. These prefabricated fibre composite components are joined using the same synthetic resin as a bonding agent.

HALE Unmanned Aerial Vehicles UAV. The structure of the UAV is also optimized by using composite materials in order to get a high strength-to-weight ratio analysis of the design structure configuration of. 2 Main wing structure The wing consists of an upper and lower shell of sandwith construction a number of ribs the main spar a nonbearing front wall a torque box and a number of chordwise stiffening strips Fig2.

The constant chord wing part consists of two inner-wing tubular spar elements each 418 m long connect to a 42 m centre-wing-box. This paper is a continuation of the first paper and presents buckling and flutters analysis. 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 purpose of this study is to analyze the impact loads on the composite sub-structures of a mini UAV due to the belly landing. Optimization procedure to design composite wing box of solar powered HALE UAV. Reducing the weight of the spars while maintaining sufficient structural integrity is important because the spar is the heaviest load bearing component in.

This is the second part on the design of a high aspect ratio HALE-UAV wing using composite materials. SMALL UNMANNED FIXED-WING AIRCRAFT DESIGN. The composite wing is up to 35m long and the composite material accounts for 65 of the structural weight.

The wing was made of a carbonepoxy laminate with orthotropic arrangement 0045-45 s. Hale Uav Composite Wing Structure Design. The spar also used a sandwich structure.

9 In particular it is very important to reduce the weight of the UAV frame while maintaining the structural performance which can reduce the energy consumption and improve the carrying capacity of the payload. Finite element software ABAQUSCAE is used to predict the stress and deformation that occurred. It features a large aspect ratio with a single wing a slender body a V-shaped tail a top three-point landing gear layout a 554 swept back 14 chord of the wing and a V-shaped tail upper 50.

A good way to meet this objective is to design an aircraft with a high aspect ratio wing enhanced lift-to-drag ratio and a lightweight composite airframe low wing loading2 This kind of aircraft is.
