Aircraft’s weighing & centering systems calibration

Dynamic Weighing Calibration Method for Liquid Flowmeters -a New Approach

In the last years, the PTB liquid flow group has been working on the development of a new method to calibrate liquid flowmeters under dynamics conditions [1,2]. Such a measurement principle is based on a dynamic weighing approach, which is able to reproduce the unit of mass flow several times, with the ultimate goal to reduce the calibration time, energy cost, and workload in liquid flow calibr...

Electrical Distribution Power Systems of Modern Civil Aircrafts

As the aircraft industry is moving towards the all electric and More Electric Aircraft (MEA), there is increase demand for electrical power in the aircraft. The trend in the aircraft industry is to replace hydraulic and pneumatic systems with electrical systems achieving more comfort and monitoring features. Moreover, the structure of MEA distribution system improves aircraft maintainability, r...

Synthetic Aperture Radar Systems for Small Aircrafts: Data Processing Approaches

The synthetic aperture radar (SAR) is considered now as the most effective instrument for producing radar images of ground scenes with a high spatial resolution. The usage of small aircrafts as the platform for the deployment of SAR systems is attractive from the point of view of many practical applications. Firstly, this enables for a substantial lowering of the exploitation costs of SAR senso...

Functional Centering

Based on empirical evidence from a free word order language (German) we propose a fundamental revision of the principles guiding the ordering of discourse entities in the forward-looking centers within the centering model. We claim that grammatical role criteria should be replaced by indicators of the functional information structure of the utterances, i.e., the distinction between context-boun...
