why adopt additive manufacturing in sqx-2y?
a liquid oxygen methane rocket requires a strong payload capacity while ensuring lightweight construction to maintain rocket performance. efficiency, cost, and iteration speed are crucial to commercial rocket development. metal 3d printing technology offers significant advantages in part structure optimization design, manufacturing complex feature combinations, and rapid prototyping of small batch parts. 3d printing processes has the advantages of high integration, lower process complexity, shorter production cycles, and reduced costs.
as a long-term partner of i-space, blt has assisted the i-space in the development of several key engine components, effectively reducing i-space’s component production cycle, saving production costs, accelerating product iteration, and enhancing development efficiency. in the early stages of developing new rocket engines, relying on 3d printing technology allows i-space to have greater flexibility in design and significantly shortens the validation cycle for design optimization iterations.
how was blt’s additive manufacturing expertise implemented in the sqx-2y program?
blt has 3d printed components including t-shaped coupling connectors/ tee joints and liquid rocket engine thrust chambers for sqx-2y. the t-shaped coupling connectors were printed by blt-s310 machine with stainless steel. the average printing time for a single piece is only 20 hours, and the formed parts exhibit high consistency in quality and performance, meeting the requirements of actual working conditions.
the liquid rocket engine thrust chamber incorporates dozens of precision-critical nozzles. metal 3d printing technology enables the integrated manufacturing of these nozzles, ensuring that the quality, precision, and performance of the parts meet the exacting demands for flawless aerospace applications. the liquid rocket engine thrust chamber is printed by blt-s310 machine with stainless steel, taking only 180 hours to complete.
