Opis:
In this article, a project of an unmanned aerial system designed for monitoring of air pollution is presented. The system consists of an autonomous unmanned aerial vehicle (UAV) equipped with a measurement head with sensors of chemical and physical properties of atmospheric air, and a ground control station arranged to store and display the collected data. The head contains modern sensors selective to the most important components of air in view of environmental pollution. Measurement data are acquired locally as well as transmitted wirelessly to a ground station. The UAV can be programmed to a particular measurement missions. The ground station dispose of a software for flight control and for visualisation of measurement results on-line. In this paper, an architecture of the entire system, a data processing performing by each subsystem, and communication methods between them are presented. This paper also includes a specification of sensors with their principles of operation, description of their metrological properties and the way, in which they are implemented in the designed electrical circuits. Results of preliminary tests in a laboratory and in a field, during a short flight, are also presented.

Opis:
The main goal of the work reported here was to expand the capability of the NRC-Aerospace spin rig by adding an on-line damage detection, discrimination and tracking system, and to develop necessary expertise that will allow for optimizing the NDE inspection periods of gas turbine engine components in this facility and minimizing undetected crack nucleation and growth and possibility of catastrophic failures. Passive eddy-current sensors and a data acquisition system able to simultaneously measure blade deflection and tip clearance were selected to monitor health of rotating components. Before application of the system in the spin rig, the system was tested with a rotor rig to check sensor responses to deliberately induced changes in blade tip positions in both radial and circumferential directions. The monitored disc had 12 bolts simulating aerofoils that could be turned into threaded holes to extend or shorten the protruding parts of the bolts. On the other hand, bolt vibration was not excited and analysed during the experiment. Lessons learned on the rotor rig are used to prepare and plan spin tests in vacuum chamber.
