MXOD Flight 1: Feed System and Electronics Architecture

The Mach 10 Oblique Detonation (MXOD) flight program comprises a series of flight experiments focused on detonation-based propulsion fundamentals. Flight 1 serves as the inaugural mission in the flight series and is designed to investigate the stabilization of an Oblique Detonation Wave (ODW) at altitudes between 25-30 kilometers and speeds ranging from Mach 9 to 10. This experiment is a first in stratospheric ODW testing, and relies on novel solutions to the development of a flight ready fluid and electronics system. The hardware configuration for the MXOD Flight 1 feed and electronics subsystems is presented. The configuration is validated against broad mission requirements, and key design decisions are outlined in the context of flight reliability, fuel injection capabilities, telemetry requirements, and control capabilities. The resulting framework establishes a scalable configuration option for air-breathing hypersonic payloads, and serves as the baseline architecture for subsequent missions in the MXOD flight campaign.
