Embodiment
Turn to realize jet pipe ejection air-flow, according to an embodiment of the invention a kind of fluid control cincture dividing plate dual vector jet pipe as shown in figs. 1 and 3 comprises:
The inner flow passage of spout body, comprises venturi anterior contraction section 1, nozzle throat 3, nozzle divergence cone 4, wherein, jet pipe contraction section 1, nozzle throat 3, nozzle divergence cone 4, to be linked in sequence;
Install dividing plate 8 free to rotate in nozzle divergence cone 4, the two ends of the installation shaft 9 of dividing plate 8 are arranged on jet pipe longitudinal wall 12(Fig. 3) on, whole installation shaft is near the nozzle wall face at jet pipe cross wall 2 place.Can mineralization pressure cavity 6 between the internal face of dividing plate 8 and jet pipe cross wall;
Be arranged on the hole/seam 5 jet pipe wall in pressure cavities 6 in-scope can being introduced pressurized gas.
Fig. 4 is the schematic perspective view of the fluid control cincture dividing plate dual vector jet pipe of the embodiment of the present invention shown in Fig. 3.
According to a further embodiment of the present invention, as illustrated in fig. 1 and 2, above-mentioned fluid control cincture dividing plate dual vector jet pipe also comprises: be arranged on the wall of nozzle divergence cone 4, for the groove 7 of buried dividing plate flange 10.
As shown in Figure 2, according to one embodiment of present invention, dividing plate 8 has the profile of T-shaped substantially, and comprises: installation shaft 9, and dividing plate 8 freely can rotate around installation shaft 9; Dividing plate flange 10; Dividing plate base plate 11.
When not needing vectored thrust, stop bleed.Because the main flow in jet pipe has higher pressure, dividing plate 8 is subject to the pressure of the main flow in jet pipe, and dividing plate flange 10 inserts the groove 7 on jet pipe wall voluntarily, and dividing plate base plate 11 is fitted on the internal face of jet pipe, and now jet pipe and common jet pipe are as good as.When needs thrust vectoring, open bleed, pressurized gas through hole/seam 5 introducing, dividing plate 8 is rotated thus with jet pipe wall mineralization pressure cavity 6, the discharging jet changing main flow thus to, realize Thrust vector angle.Before dividing plate flange 10 departs from groove 7 completely, because pressure cavities 6 is closed, high-pressure bleed air can not flow out, and bleed flow is zero can produce vectored thrust in theory; When improving bleed air pressure further, dividing plate corner becomes large, and when making dividing plate flange 10 depart from groove 7 completely, pressure cavities 6 is no longer closed, and pressurized gas flow out from pressure cavities 6, forms time stream.
