On Cup Anemometer Rotor Aerodynamics

The influence of anemometer rotor shape parameters, such as the cups' front area or their center rotation radius on the anemometer's performance was analyzed. This analysis was based on calibrations performed on two different anemometers (one based on magnet system output signal, and the other one based on an opto-electronic system output signal), tested with 21 different rotors. The results we...

Ionospheric Effects on Network-RTK

Ionospheric Effects on Network-RTK A part of the atmosphere is ionized by the UV radiation from the Sun. This part is often referred to as the ionosphere. The resulting free electrons influence the GNSS signals as they propagate through the ionosphere. We have studied how the spatial variations of electron density in the ionosphere affect measurements with network-RTK. The aim is to predict wha...

Multiprocessing On Supercomputers for Computational Aerodynamics

Very little use is made of multiple processors available on current supercomputers (computers with a theoretical peak performance capability equal to 100 MFLOPS or more) in computational aerodynamics to significantly improve turnaround time. The productivity of a computer user is directly related to this turnaround time. In a timesharing environment, the improvement in this speed is achieved wh...

Re-engineering Aerodynamics Education

Aerodynamics curriculum in undergraduate engineering has reached a critical juncture forcing the need for change in the traditional, largely theoretical curriculum and lecturer/listener pedagogy. The role of aerodynamics in aerospace engineering, while still important, is no longer the dominant driver in aircraft design. Furthermore, industry, government, and academia --the likely employers of ...
