Design and Operation Analysis of Hybrid AUV

Hybrid autonomous underwater vehicle (HAUV) is a collaboration concept between sea glider and autonomous underwater vehicle. The specific characteristics of sea glider are long endurance, wide range, and limited payload or sensor to support the mission. Different from the AUV as the real surveillance underwater vehicle, they can have almost all range of payloads and emergency system but with limited endurance and range if compared with the sea glider system. Dual concepts of the characteristics will be combined. The main mission for this vehicle is adopted from AUV but for submerge and surfacing mode adopted from sea glider concept with their buoyancy engine. This paper describes a step-by-step method to design this vehicle and some core analysis to support overall design concept and the operation that will be conducted on this hybrid AUV.

Design and Operation Analysis of Flying Trimaran USV

One of important design aspect of USV is the coverage area and cruising speed. Some conventional USV have constraint on maximum speed. That’s why with some earlier USV that’s had been developed on Center for unmanned system Studies –Institut Teknologi Bandung have some approach to make so efficient as possible on the hull design. But on this new USV from this research center make some new approach and solution with the new propulsion system and control surface. This paper will be presents about design and operation analysis of Flying catamaran USV. The design will be focused on Propulsion and distribution of hydrodynamic and aerodynamic aspect of this vehicle. Computational Fluid Dynamics methods will be the main analysis tools for this design.

Design of SWATH Based Unmanned Surface Vehicle

Unmanned surface vehicle promises some advantages for civil and military application. Some approach to improve and design the better solution become more attractive in all aspect. Indonesia as the maritime country have an specific needs of kinds solution for the coastal area preservation. USV is the one of the unmanned solution for Naval technology application. USV that have been developed by Center for Unmanned system studies is based of SWATH (Small wetted area twin hull) technology. With this concept, it makes this vehicle not closely as surface definition but more than likes subsurface vehicle [7]. SWATH type naval architecture need a largely part that’s fully submerged beneath the surface. Some of Design aspect for this vehicle will be described on this paper. This vehicle prototype have dimension (L x W x H) :1622mm x 862 mm x 923 mm, most of the construction for development of this vehicle based on composite. Composite technology offered some advantage. Some construction design for this prototype architecture will be described on this paper.
