GE Aerospace Achieves Milestone in Solid Fuel Ramjet Technology with Successful Flight Tests

GE Aerospace announced the successful supersonic captive carry flight tests of its Atmospheric Test of Launched Airbreathing System Flight Test Vehicle, representing a major milestone in advancing solid fuel ramjet propulsion technology. The tests, conducted as part of the ATLAS program, involved three successful flights where the system was carried aloft on a Starfighters F-104 aircraft and reached supersonic speeds. This achievement demonstrates the viability of SFRJ technology in realistic atmospheric conditions for the first time.

Mark Rettig, vice president and general manager of Edison Works Business and Technology Development at GE Aerospace, emphasized the significance of these tests, noting that captive carry testing of reusable flight test hardware enables more frequent testing in realistic atmospheric conditions to better understand system behavior. The ATLAS project received funding from the Department of War via Title III of the Defense Production Act specifically to scale up air-breathing propulsion technology for extending the range of munitions.

The current phase of ATLAS is designed to validate key performance capabilities of solid fuel ramjets during flight, providing essential insights for future systems requiring enhanced speed, range, and responsiveness. These tests represent one component of GE Aerospace's broader investments in advanced high-speed and hypersonic propulsion technologies. The company's strategic moves include the acquisition of Innoveering in 2022 to accelerate its hypersonics portfolio and significant test infrastructure upgrades announced earlier this year at facilities in Evendale, Ohio; Bohemia, New York; and Niskayuna, New York.

The successful flight tests using Starfighters Space's supersonic F-104 flight capabilities demonstrate the practical application of ramjet technology in military contexts. The enhancements to GE Aerospace's testing infrastructure will enable higher-Mach, mission-relevant testing at a scale not previously possible, positioning the company at the forefront of hypersonic propulsion development.

This advancement in solid fuel ramjet technology has significant implications for future defense systems, particularly in extending the range and capabilities of munitions while maintaining high-speed performance. The successful demonstration of this technology in flight conditions marks a critical step toward operational deployment and represents GE Aerospace's commitment to advancing propulsion technologies that could redefine military capabilities in high-speed scenarios.
