A Mathematical Model of Pressure Traverse of a Pitot-static System Cross Section 000_11.pdf

The article considers the results of researching pitot-static systems. The authors have been created mathematical model of pressure traverse of a pitot-static system cross-section. The model has shown that shifting the arrangements of static pressure tap holes along the receiver length has no effect on pressure distribution over the receiver surface essentially. From the results of mathematical modelling, the authors have obtained the data array for a model of a pitot-static system in order to detect surface pressure. The method of pressure perception compensation on the basis of mass balance has been suggested. Due to this, improvement of static pressure perception accuracy can be provided not only by shifting the arrangements of static pressure tap holes along the receiver cross section perimeter but also by changing the diameter of holes. This can eventually help to achieve required characteristics of static pressure perception of a chamfer angle and incident flow speed.
