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.

General Education for Civil Engineers: Sustainable Development

Journal of Professional Issues in Engineering Education and Practice, 2008
The ABET criteria for engineering programs no longer has a requirement for humanities and social sciences but instead requires a general education component that complements the technical component of the curriculum. Achievement of the outcomes called for in the ABET criteria and the ability to apply the constraints listed in ABET Criterion 3 can be ...

Modeling and generation of seismic ground motion for active control in civil engineering

2015 3rd International Conference on Control, Engineering & Information Technology (CEIT), 2015
The Artificial Accelerograms have been developed for assessing the dynamic response of structures. Considering seismological properties of the site are necessary for the best simulation of accelerograms. In a simplified seismic analysis, we model only the strong phase of the seismic signal. The latter is then assumed to be stationary during this period.

Application of microwave aquametry in civil engineering and in power generation

Measurement Science and Technology, 2007
The first part of this paper is devoted to microwave moisture-measurement (aquametry), starting with an overview of the work performed by researchers involved in using microwave (or high-frequency electromagnetic) signals for moisture measurement, as well as in non-destructive testing and evaluation (NDT&E) of mainly concrete.
