| Abstract Scope |
Small rocket nozzles used in reaction control systems and similar applications have often been manufactured using the niobium alloy C-103 due to its relatively good formability. However, cost and availability of the alloy has recently been a challenge and the performance of the alloy is not exceptional for its class. In this talk we will explore using additive manufacturing to produce prototypical nozzles from other alloy systems designed for use in short burn transient regimes using a number of additive manufacturing methods. Additive manufacturing enables the production of a range of alloys and avoids formability challenges, but may introduce other concerns around defects and surface quality. Use of less costly alloy chemistries in coated or layered structures could also provide a performance benefit and provide a more economical solution. Results from a variety of alloys and manufacturing methods will be compared for their applicability to various use cases. |
