| 摘要 |
The invention is a system for determining the physical characteristics of an incident fluid flow stream over a surface of a vehicle relative to an axis thereof. In detail, the invention includes at least one first pressure sensor (22) mounted on the surface, the at least one first pressure sensor (22) for receiving dynamic pressure signals generated by the convected boundary layer of the fluid flow stream and providing an output signal representative thereof. At least one array (24) of second pressure sensors (24A-24I) is positioned downstream of the at least one first pressure sensor (22), the second sensors (24A-I) of the at least one array (24) each of said second pressure sensors (24A-I) providing a second output signal representative of the above pressure signals received thereby. A computer system (36) is adapted to receive the first and second signals and to calculate the angular direction of the fluid flow relative to the axis and the velocity thereof.
