Compass System

In this paper, methods of defining heading are enumerated and the limitations of magnetic and gyroscopic devices are analysed in detail. Particular attention is paid to the development of the rotated race principle which is likely to be responsible for a large improvement in the basic azimuth gyro. The gyro-magnetic combination is scrutinized and the errors inherent in this compass system are classified. The possibility and consequent effect of diminishing certain categories of error are presented. The current position is summarized and an attempt is made to suggest possible future trends. The authors are, respectively, with Smiths Aircraft Instruments and the Sperry Gyroscope Company.

Consumption Goals

The common factor for all airlines in reducing aircraft operating costs is improving fuel economy. Many international organizations such as EASA, ICAO or ICCT as well as aircraft operators put strong emphasis on improving aircraft fuel efficiency not only for economical but also for ecological reasons. It can be noticed that biggest improvements are achieved through implementation of new aircraft models and engines. Fuel consumption goals have been set by ICAO to achieve an annual improvement of 2% from year 2020 to 2050, however according to some experts this goal is probably is not going to be met as industry is lagging approximately 12 years behind this plan due to technological and economic reasons.

Comprehensive Picture

The Hydraulic Laboratory of Liège University, Belgium, is historically considered from its foundation in 1937 to the mid-1960s. The technical facilities of the various Buildings are highlighted, along with canals and instrumentation available. It is noted that in its initial era, comparatively few basic research has been conducted, mainly due to the professional background of the professors leading the establishment. This state was improved in the past 50 years, however, particularly since the Laboratory was dislocated to its current position in the novel University Campus. Biographies of the leading persons associated with the Liège Hydraulic Laboratory are also presented, so that a comprehensive picture is given of one of the currently leading hydraulic Laboratories of Europe.
