The Mathematical Model of the Static Pressure Flowing Reciever 000_8.pdf

The article considers the matters of constructing mathematical models of the static pressure following receivers (SPFRS) designated for sensing static pressure on helicopters in a range of airspeeds to 250…350 km/h. SPFRS consist of contracting and diffusing parts. The mathematical model of SPFRS was developed in accordance with results of experimental researches for defining static pressure, dynamic pressure, speed, speed inaccuracy, altitude inaccuracy. The adequacy of the obtained mathematical models is checked through the comparison with the results of experimental researches. The models allow getting reliable data at the contractor convergence angle in 30-70 degree, the diffuser aperture angle in 8-14 degree, the diaphragm coefficient in 0.15-0.45, windblast speed in 20-250 km/h. The influence of separate components (a contractor and a diffuser) on SPFRS pressure coefficient and correlation between experimental data and the results obtained with the mathematical model are considered. With the use of the obtained mathematical models, the process of developing receivers with predicted metrological characteristics can be automated. The ability to take up receivers with required form factors for the specific control object on the original development cycle promptly has been appeared.

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.

Mathematical Model for Pitot-static Probe 35_8.pdf

The article deals with mathematical modeling problems of the air pressure probes composed of the front cylindrical receiving tube having inside conical flow stagnation chamber and static pressure holes. Basic mathematical models for the air pressure probes were derived from the mathematical modeling intended for determination of static pressure, dynamic pressure, velocity, velocity and altitude errors. The adequacy of the received mathematical models is checked by comparison against the experimental research findings. Experimental studies were carried out in the T-129 wind tunnel of TsAGI with nozzle-jet simulator. These models allow to get true data at such parameters as the cylindrical tube radius over the range 6.5 to 8.5 mm, start tube distance to the static pressure holes of 45 to 70 mm, downwash angle of 0 to 90 degrees, incident airflow velocity at 50 to 250 kmh. The received mathematical models enable to automate the engineering process of Pitot-static probe with metrological performance predictions. This gives the ability to make a quick selection of probes with design parameters required for a specific control object at the initial development stage.
