The research climate, in the US and in Europe, is now undergoing considerable change. While the prevailing trends are different, the research scenes on both sides of the Atlantic are becoming more similar than they were in the past. Long term effects will be described and contrasted to transient short-term effects. What is happening in electronics is a good indicator ...

It has been only within the last decade that electrical science has played any important part in block-signaling. Previous to that time the only use for electrical apparatus in signaling was in the form of a few batteries for the track circuit, and for the operation of pin-valve magnets in the electropneumatic system of signaling and interlocking. But in the ...

The research climate, in the US and in Europe, is now undergoing considerable change. While the prevailing trends are different, the research scenes on both sides of the Atlantic are becoming more similar than they were in the past. Long term effects will be described and contrasted to transient short-term effects. What is happening in electronics is a good indicator of a more general evolution, since technological progress in electronics has always been much faster than in mechanical and electrical power engineering. The rapid penetration of electronics into electric power systems, caused by the energy crisis, creates some distinct problems having particular impact on the innovation climate.
It has been only within the last decade that electrical science has played any important part in block-signaling. Previous to that time the only use for electrical apparatus in signaling was in the form of a few batteries for the track circuit, and for the operation of pin-valve magnets in the electropneumatic system of signaling and interlocking. But in the past few years electricity has come steadily into use as a means of transmitting the operating power, until at the present time it is the prime element in signaling.
Aero-engine blades always failure due to impact of foreign object damage in service. Damnification and consequent fracture failure of blade is one of the main failure modes for the compressor blades in aero-engine. Damage characteristic on blades caused by different kind of material are various. Observation on damaged surfaces, trace analysis and surface element analysis by means of SEM and X-ray energy spectrum are effective methods to estimate the attribute, component and outline of foreign object. In this paper, analysis on several cases of FOD are introduced. The features, principles and rules of several typical FOD modes are summarized through failure cases analysis.
A dual-purpose chemical applicator for flooded paddy field was developed to boost agricultural mechanization in rice production and also to overcome the safety concern of hazardous spray drift during chemical application by the paddy farmers. The dual purpose applicator was mounted on a high clearance tractor and could also be used with remote-controlled buoyant vehicle which was propelled by electric motors within the flooded paddy field. The machine performances for both granular and liquid chemical application were reported. Results from the experimental tests suggest that the average effective field capacity for the equipment with a prime mover was found to be 0.89 ha/hr or 7.12 ha/man-day for a 8 hour working day.
This paper presents both simulation and experimental results of micro-drone rotor blade electromagnetic scattering. The focus of this work is investigating the variation of these reflections as a function of variables such as polarization, frequency and azimuth angle. The simulation results clearly show a strong variation in scattering with azimuth and frequency. Experimental validation of these variations was investigated and similar trends in azimuth were found. The Doppler components from an operational micro-drone in varying polarizations are shown, these demonstrate the expected signals received by a real radar system.
As gas turbine manufacturers strive for improved efficiency the turbine operating temperatures increase which can only be met by improvements in blade and coating materials together with advances in cooling and coating technologies. The ultimate, and possibly the only, environment capable of testing modem blade systems is in a working engine and it is from this environment that instrumentation a range of instrumentation technologies must acquire valid blade performance data. A critical blade parameter is the surface temperature distribution and this paper reviews the various technologies currently applied to blade surface temperature distribution measurement. Optical Pyrometry is discussed in more detail and the definition of an integrated high bandwidth detection and data collection system developed. The system developed collects turbine and stores radiance measurements at the rate of 1 million per second and this paper explores the benefits that can accrue from this approach in areas such as noise reduction and blade scanning techniques. The output from such a system is a data file representing a 'thermal image' of all the blade surfaces viewed by the pyrometer. The conversion of the 'thermal image' into a temperature image is discussed and the role of complimentary measurement methods in refining the temperature image is reviewed. The integration of measurement techniques limits the ability of suppliers to deliver an 'Off-The-Shelf' measurement capability. In the light of this the limitations of the system outlined in the paper are discussed and the need for collaborative effort between the system supplier and the users technical departments emphasised.
In wind energy conversion system the wind turbine captures the kinetic energy associate with the wind for the production of electricity with the help of generator. Performance of a wind turbine is dependent upon its operating conditions such as wind speed as well as its design parameters such as blade radius, blade pitch angle, weight etc. In the present paper, authors have made an attempt to develop a MATLAB/SIMULINK model of wind turbine. Model as developed is suitable to investigate its performance under constant as well as variable speed mode. Simulated results as obtained are found to be useful to predict the effect of wind speed and blade pitch on the performance of wind turbine under two operating modes.
A blade-plane or a point-plane configuration in a dielectric liquid is considered. For high electric injection from the blade or the point takes place with ions of the same polarity. The Coulomb force acting upon the injected charges generates an electrohydrodynamic (EHD) flow, referred to as a charged jet. These EHD charged jets can be approximated as a free boundary layer flow, and a similarity analysis can be performed under some simplifying assumptions. Experimental observations for the case of blade-plane geometry are presented.
This project will add new definitions and revise existing definitions to bring the document up to date. Altitude correction factors will be revised to reflect the recommendations of the Switchgear Committee "Common Clauses" working group.
