Engineering aircraft systems is a complex task. Therefore models and computer simulations are needed to test functions and behaviors of non existing systems, reduce testing time and cost, reduce the risk involved and to detect problems early which reduce the amount of implementation errors. At the section Vehicle Simulation and Thermal Analysis at Saab Aeronautics in Linköping every basic aircr...

HEDRICK, H. G. (General Dynamics/Fort Worth, Fort Worth, Tex.), C. E. MILLER, J. E. HALKIAS, AND J. F. HILDEBRAND. Selection of a microbiological corrosion system for studying effects on structural aluminum alloys. Appl. Microbiol. 12:197200. 1964.Two laboratory methods, a metal-strip test and a tank test, were evaluated as microbiological corrosion systems for producing corroded test specimens...

A hybrid electric vehicle (HEV) has two types of energy storage units, electricity and fuel. Electricity means that a battery (sometimes assisted by ultracaps) is used to store the energy, and that an electromotor (from now on called motor) will be used as traction motor. Fuel means that a tank is required, and that an Internal Combustion Engine (ICE, from now on called engine) is used to gener...

This paper concerns the problem of how companies, who seek to develop new technology, can successfully capitalise on the whole pool of resources and technologies available within their network, whilst at the same time cope with the problem of loss of control of knowledge and technologies to other parties in their network. Taking point of departure from their previous conceptual and empirical wo...

A standard problem in large tanks at oil refineries and petrol stations is that water and fuel usually occupy the same tank. This is undesirable and causes problems such as corrosion in the tanks. Normally, the water level in tanks is unknown, with the problems that this entails. We propose herein a method based on surface plasmon resonance (SPR) to detect in real time the interfaces in a tank ...

Laser Spectroscopy provides a non-intrusive method for measuring the concentration of a species in a sample. This paper is a part of the development of employing laser spectroscopy techniques outside of a lab setting. Monitoring the presence of gaseous oxygen within a fuel tank is of great importance due to the volatility of the fuel/oxygen mixture and the threat it creates to the area surround...

Using an aircraft fuel tank as an industrial case-study, the paper describes some recent research developments at BAE SYSTEMS that allow the airframe and systems life-cycles to become better aligned. In particular, the paper demonstrates that the design and analysis of the fuel system can be integrated with the airframe structure. This will reduce qualification times in the future and enable Si...

This review describes recent research in the development of tank systems based on complex metal hydrides for thermolysis and hydrolysis. Commercial applications using complex metal hydrides are limited, especially for thermolysis-based systems where so far only demonstration projects have been performed. Hydrolysis-based systems find their way in space, naval, military and defense applications ...

Trans World Airlines (TWA) flight 800 was only twelve minutes into a July 19, 1996 trip from New York to Paris when an in-flight explosion destroyed the passenger jet, plunging it into the Atlantic with 230 people on board. The aircraft was climbing south of the Long Island coast near East Moriches, New York when suddenly, portions of the Boeing 747-131 fuselage beneath the center wing fuel tan...

Path planning is indispensable in performing the inspection task using continuum robot in the environment like aircraft fuel tank. In order to obtain the optimal path and make it feasible for the robot traversal, a path planning strategy based on region division is put forward. The aircraft fuel tank is divided into several regions and mapped to a two-dimension plane by using dimension reductio...
