For this reason, the technical solution adopted in the utility model is as follows: a kind of wind-tunnel two-dimensional flow field test railroad, and comprise pedestal and be fixedly mounted on the horizontal slide rail on pedestal, it is characterized in that, described horizontal slide rail is marked with scale and is provided with at least one level tube;
The built-in transversely movable cross sliding clock of described horizontal slide rail, the top of this cross sliding clock is fixedly connected with the bottom of a upright slide rail, and described upright slide rail is marked with scale and is equipped with one can the upright slide block of vertical movement;
Wind-tunnel two-dimensional flow field test suite described upright slide block is equipped with.
The utility model installs level tube on horizontal slide rail, installs whether level by the position judgment horizontal slide rail of bubble in level tube; Reference mark on horizontal slide rail simultaneously, for measuring the position of cross sliding clock in process of the test.Cross sliding clock is fixedly connected with upright slide rail, makes cross sliding clock and upright slide rail form entirety, and adjusts the horizontal level of upright slide rail by cross sliding clock.By the slip of upright slide block, the height of adjustment wind-tunnel two-dimensional flow field test suite, realizes the test of wind-tunnel wind profile.The testing range (i.e. meter full scale) of horizontal slide rail and upright slide rail is arranged according to testing requirements.
Further, described wind-tunnel two-dimensional flow field test suite comprises five-hole probe, is connected to leather hose and the pressure instrumentataion of five-hole probe one end, and described five-hole probe is connected with described upright slide block by web member, and described leather hose is connected with pressure instrumentataion.During use, the other end of five-hole probe is parallel with incoming flow.
Further, described cross sliding clock employing buckle positions with horizontal slide rail and is connected, and guarantees that in process of the test, cross sliding clock can be fixed on the assigned address of horizontal slide rail.
Further, described cross sliding clock adopts to weld with upright slide rail and is connected as a single entity, and connection is between the two more firm.
Further, described horizontal slide rail adopts screw to be fixedly mounted on pedestal.
The beneficial effect that the utility model has is: 1) horizontal slide rail according to the requirement of wind tunnel test, can be arranged on the correct position of test chamber by the utility model, and the position of level, upright slide block can be adjusted according to the coordinate of measuring point.2) the utility model can adjust horizontal level and the height of measuring point quickly and easily, ensures that each point position accurately, reliably simultaneously, and greatly reduces complicated processes when measuring point is installed, effectively improve measuring accuracy and the efficiency of wind-tunnel two-dimensional flow field.
