Gaseous Emissions Results from a Three-Cup Flametube Test of a Third-Generation Swirl-Venturi Lean Direct Injection Combustion Concept

摘要

This paper presents gaseous emissions results from flametube tests of a low-NO_x aircraft gas turbine engine combustor concept. The low-NO_x combustor concept is a third-generation swirl-venturi lean direct injection (SV-LDI-3) design. It was developed to meet the NASA Advanced Air Transport Technology project goals: the development of a combustor suitable for a small-core engine with NO_x emissions 80% below the CAEP/6 standard. Flametube testing showed this design would meet the project goals, with a landing and take-off (LTO) NO_x reduction estimated to be 85%-89% with respect to CAEP/6.
