Description
Technical field
The utility model relates to exerciser performance test field, and particularly a kind of exploration type surveys static pressure sensing head.
Background technology
When demonstration test device or engine performance, can carry out the air flow rate of calculation engine by measuring pressure and temperature, be the important method that performance test measures static pressure at exerciser or engine shell surface perforate (φ≤0.5).The position degree in wall hole, crudy, directly has influence on the precision of surveyed static pressure.Moreover, when exerciser or engine operation, air-flow flow at high speed, but be not carry out moving according to ideal orientation, the indefinite air motion in direction constantly impacts wall, can cause certain thickness regions of turbulent flow in the gas flow between the heart and wall, forms boundary-layer, cause the static pressure error measured bigger than normal, and then the performance test that impact is overall.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of exploration type and surveys static pressure sensing head, and concrete technical scheme is as follows:
A kind of exploration type surveys static pressure sensing head, comprises plug, stagnation cover, transfer tube, mount pad, pole and bleed mouth;
Described plug is plugged on transfer tube, by being welded and fixed;
