Hydrocarbon-fueled ramjet/scramjet technology program. Phase 2: Test plan

摘要

United Technologies Research Center (UTRC) has prepared a test plan for hydrocarbon ramjet/scramjet combustor testing under Phase 2 of a NASA LaRC program to provide combustor component technology for a research-scale scramjet engine model. This test plan addresses the development of the combustor technology applicable to the modular ramjet/scramjet engine concept devised by UTRC for successful implementation of an underslung, hydrocarbon-fueled engine for supersonic/hypersonic missiles. Execution of this test plan will provide a firm basis for the design of this engine through two major test stages: (1) a Combustor Design Definition Stage in which critical design criteria for an axisymmetric modular combustor will be generated; and (2) a Combustor Performance Evaluation Stage during which the essential component technologies will be merged to provide a convincing demonstration of the combustor operation over the appropriate range of simulated flight condition.
