TEST DEVICE OF COLD FLOW AND LEAK OF THE COMBUSTOR USING COAXIAL SWIRL INJECTOR

摘要

The present invention relates to a water flow test device of the combustor confidential and applying the coaxial swirl injector, a number of particularly The liquid rocket engine comprising a combustor coupled to a coaxial swirl injector; And airtight means for shielding the oxidant nozzle and fuel nozzle is inserted into the oxidant and fuel nozzles of the spray nozzle of the coaxial swirl injector; Is formed of a disc shape, the tab on the edge formed by the combination of the burner head and the bolt and to enable a plurality of coaxial swirl injector and the corresponding bolt for sealing plate and the tabs are formed in the support position of the combustor; And a support bolt that is fastened to the tab for supporting bolt of the sealing plate to support the airtight unit; Induction pipe is fastened to the tab for supporting bolt of the sealing plate to be measured is the flow rate of the coaxial jet swirl injector; And the liquid fuel supply line of the burner and an oxidant supply line installed inside characterized in that it comprises a pressure sensor for sensing the pressure thereof. Maintaining the confidentiality of each coaxial swirl injector according to the present invention as described above, and any one of, by measuring the flow rate of the injector to create variations of the review and the injector through the airtight and water flow test of the mixer head of the LRE can determine whether or not.
