Aerospace products are typically high-tech, high quality and low volume. They are produced by specialised geographically dispersed companies. The production is dominated by a large amount of engineering. In the engineering phase each company makes extensive use of real-time simulation for its own (sub) systems. At the same time the aerospace industry is becoming more competitive. This way of wo...

In this paper a number of issues on impactin mechanical systems are presented.Emphasis is on modelling, simulation andcontrol in a real-time setting for aerospaceapplications.

The availability of reliable and efficient turbulent flow simulation methods is highly beneficial for wind energy aerospace developments. However, existing suffer from significant shortcomings. In particular, the most promising (hybrid RANS-LES methods) face divergent developments over decades, there a waste resources opportunities. It very likely that this development will continue as long lit...

The Aerospace Systems Design Laboratory at the Guggenheim School of Aerospace Engineering, Georgia Institute of Technology, has recently created the "Collaborative Design Environment" (CoDE), a nextgeneration design facility supporting efficient, rapidturnaround conceptual design. The CoDE combines cost-effective, off-the-shelf information technology with advanced design methodologies and tools...

Over the past 30 years, numerical methods and simulation tools for fluid dynamic problems have advanced as a new discipline, namely, computational fluid dynamics (CFD). Although a wide spectrum of flow regimes are encountered in many areas of science and engineering, simulation of compressible flow has been the major driver for developing computational algorithms and tools. This is probably due...

This paper presents the simulation performance of Dual Active Bridge (DAB) DC-DC converter for high power density aerospace applications. The DAB converter topology has been chosen as it features high power density, high efficiency, bidirectional power flow capability, inherent soft switching, galvanic isolation and low number of passive components. Hence the converter is a candidate for high p...

The subject of uncertainty analysis in complex systems design is a broad and bourgeoning field of study. This paper focuses on only three very specific areas of current propulsion research wherein uncertainty plays a pivotal role in the problem formulation. The first is probabilistic approaches to matching engine cycle models to test data. Engine cycle models must have a high confidence of repr...

Possible approaches to the mathematical description of different types of flexible flying vehicles (FFV), and also the principles of software development for control system synthesis, dynamic properties research and FFV motion simulation are observed. The peculiarities of the program package specially created for such purposes are described. It includes the library of program modules designed o...

There are several method for forming bulk material, such as forging, rolling and extrusion. Every of these methods have advantages and dis-advantages of their selves. Forging process is one of the most common of them that include a die, press and in some case heater with controlling system, and has a special place in automotive, military and aerospace industries due uniformity of the final prod...
