Technology for liquid oxygen turbopump A compact, high-pressure LOX turbopump was created, built, and put to the test. The pump is a single-stage centrifugal type, and a single-stage partial-admission axial-impulse turbine powers the pump.
The pump is a single-stage centrifugal type, and a single-stage partial-admission axial-impulse turbine powers the pump. Design parameters were a pump flow rate of 16.4 Kg/s, a pump discharge pressure of 2977 N/sqcm, and an operating speed of 7330 rad/s. A self-compensating axial thrust balance piston is built within the turbopump to reduce axial thrust strains on the bearings during steady-state operation.
At an inlet temperature of 1041 K and a design pressure ratio of 1.424, testing of the turbopump was accomplished using a gaseous hydrogen high-pressure flow to drive the turbine, which is typically pushed by LOX/LH2 combustion products. The performance of the LOX seal, the head-flow efficiency, the suction performance, and the balance piston performance of the test data collected with the turbopump are all included.
The Global Liquid oxygen turbopump market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
In terms of bulk and specs, the 3D printed LOX pump was tested in a flight-ready design, while the turbine utilized in the test was machined and not flight-ready. Since they are working with liquid oxygen in the pump at 30,000 approximately one megawatt of power from the turbine, it is quite essential that Launcher’s first successful turbopump test was a success. Any irregularity or friction between the rotor and the stator in this type of atmosphere of 4,000 discharge pressure can cause a quick, unplanned disassembly.
A two-minute test using liquid nitrogen at minimum RPMs for a 3D manufactured LOX turbopump. In this 30-second cavitation performance test, the pump input pressure was gradually decreased to observe how that would affect the output pressure. Then they carried out a 33,000 RPM test using liquid oxygen for 30 seconds.
As expected test results have been obtained, the business is currently concentrating on the process and cost of utilizing 3D printing without tooling. The test campaign’s complete success demonstrates a substantial advancement for its roadmap as well as what else is possible using Ansys and VELO3D.
