The Hexafly-INT project intends to test in free-flight conditions an innovative gliding vehicle with several breakthrough technologies on-board. This approach will create the basis to gradually increase the readiness level of a consistent number of technologies suitable for high-speed flying systems. This paper presents a Finite Element thermal analysis of the Experimental Flight Test Vehicle, combining information coming from the flight trajectory, the structural layout, the vehicle aerothermodynamics and the thermal behavior of the preliminarily selected materials in high temperature conditions. Numerical results show the thermal performances of the selected high temperature resistant materials in moderate enthalpy flow conditions and provide fundamental information on the thermal loads to be considered for structural analyses.

Abstract The present work describes an integrated, two-phase computer-based method for fabricating marine propulsors using stereolithography. This new methodology seamlessly integrates stereolithography rapid prototyping techniques with the hydrodynamic design, structural design, and prototype testing of advanced marine propulsors in order to greatly increase the design process efficiency and reduce development time. Its use as applied to the design, fabrication, and testing of advanced propulsor prototypes for small weapon’s-scale undersea vehicles (e.g., Unmanned Underwater Vehicles (UUVs), lightweight and heavyweight torpedoes, etc.) is described in order to demonstrate specific strengths of the new method.

Aerial Vehicle

Unmanned Aerial Vehicle (UAV) is becoming increasingly popular because it can perform variety of functions. These functions include surveillance, reconnaissance, monitoring, data collection and rescue operation. The purpose of this work is to design, fabricate and fly a low weight, low cost, small size UAV for a surveillance mission. The design is carried out based on Advanced Aircraft Analysis (AAA) software. The design process starts with the design specifications for a typical surveillance mission. Aircraft weight, wing loading and power loading were estimated in performance sizing process. Geometry was estimated using preliminary sizing. Aerodynamics of the aircraft was determined, which enabled the performance and stability to be analysed. If the desired performance is not achieved, the sizing is readjusted until a final design is reached. The aircraft was manufactured using foam, carbon rods, and fibreglass. The aircraft successfully flew at the first trial flight. This was followed by a successful flight with aerial photography.

Building Information

In this works 3D modeling, design and safety management of high rise building using building information modeling (BIM) technology is carried out.. Initially a AutoCAD plan with all its salient features is developed following byelaws of high rise building. Then the 3D modeling and rendering of high rise building is done in the Revit architecture of the 2D plan which is imported from the AutoCAD. The analysis and design of high rise building is carried out using ETabs software. Apart from the structural design Mechanical, Electrical and Plumbing (MEP) services design is carried out using BIM technology . The layout of fire safety system is specified efficiently with use of BIM in co-ordination with MEP services. The application of BIM based design process resulted in considerable time reduction in compression with traditional design process and the holistic design of the high rise building is carried out with the compatibility of different softwares.

The design process in the maritime industry is characterized by a close cooperation of many diverse partners working in parallel. In this phase, standardization is used to reduce costs, to improve quality, and to shorten time to market. In this paper, an electronic system for the definition, management, and application of standardized solutions for steel structural design is presented. Information about the approach to data modeling applied and the interaction with existing applications is given.
