Summary
Static pressure sensors as designed by Elliott [1], have been rebuilt and thoroughly tested. The accuracy of the mean static pressure measurements is better than 4% of the stagnation pressure for incidence angles less than 10°. The sensors were used in a field experiment. Mean static pressure profiles were measured around a thin closed fence. The static pressure profiles proved to be dependent on the thermal stratification of the atmosphere. The pressure difference around the barrier, however, decreased somewhat with height but was more or less independent of the thermal stratification.
Zusammenfassung
Statische Druckaufnehmer nach dem Entwurf von Elliott [l] sind nachgebaut und eingehend getestet worden. Die Genauigkeit der Druckmessungen ist besser als 4% von dem Staudruck für Anstellwinkel weniger als 10°. Die Druckaufnehmer sind bei statischen Druckmessungen in freiem Feld angewendet worden. Um einen dichten Zaun wurden die statischen Druckprofile gemessen. Es zeigte sich, daß die statischen Druckprofile von der thermischen Stabilität der Atmosphäre abhängig waren. Der Druckunterschied um den Zaun nahm mit der Höhe etwas ab, war aber mehr oder weniger unabhängig von der thermischen Schichtung.
