Civil turbofan engines thrust generic model

IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society, 2012
Engine model is one of the most important items in aircraft simulation, because all aircraft stability parameters, as well as its performance in climbing, and accelerated flights, depend on the propulsive force developed by the power plant.

An Integrated Starter/Generator for a Large Civil Aero-Engine

3rd International Energy Conversion Engineering Conference, 2005
*† ‡ § . This paper considers the feasibility of incorporating a switched reluctance starter generator within the high -pressure (HP) region of a large civil aero -engine, specifically in terms of achievable power densities, inverter rating, machine losses and the consequent cooling requirements. The high -pressure shaft of a typical large turbo -fan e

Second Generation of Active Structural Control in Civil Engineering

Computer-Aided Civil and Infrastructure Engineering, 1996
Abstract: Research and development in active control of civil engineering structures in the United States has approximately a 20‐year history. Under the leadership of the U.S. National Science Foundation in forming the U.S. Panel on Structural Control Research and in launching a program initiative in the area of structural control, there has been a ...

A new generation of concrete in civil engineering

Journal of Materials Processing Technology, 2000
Abstract This paper presents current tendencies in the state-of-the-art in research on technology development in a new generation of cement-based concrete. The classification of such concrete and its characteristic physical properties that have been difficult to achieve up to the present time for so-called ordinary concrete are presented.

A head start for the next generation of civil engineers

Proceedings of the Institution of Civil Engineers - Civil Engineering, 2015
The UK Headstart initiative, which offers 16–17 year olds a chance to spend a week at university on an engineering taster course before making their final degree choice, received over 3000 applications last year – the highest in its 17 year history. Estelle Rowe of EDT reports.

Three stage generalized flowshop: Scheduling civil engineering projects

Journal of Global Optimization, 1996
We model the working of a civil engineering firm concerned with land development as a three stage flexible flowshop with weak chain precedence constraints and where preemption is allowed. The scheduling objective is to minimize the total tardiness for all the projects.

Structural Re-Use of De-Commissioned Wind Turbine Blades in Civil Engineering Applications

American Society for Composites 2019, 2019
The production of wind energy worldwide has increased 20-fold since 2001. Composite material wind turbine blades, typically designed for a 20-year fatigue life, are beginning to come out of service in large numbers. In general, these decommission blades,
