GE Aerospace has unveiled its comprehensive hypersonics programme at its Research Center in Niskayuna, demonstrating what is believed to be a world-first hypersonic dual-mode ramjet (DMRJ) rig test with rotating detonation combustion (RDC) in a supersonic flow stream.
This could help enable high-speed, long-range flight with increased efficiency. The milestone and overall portfolio of programs position GE Aerospace to pursue multiple opportunities in the hypersonic sector as it prepares to launch as a standalone company in Q2 of 2024.
The successful high-speed propulsion DMRJ demonstration is part of a comprehensive portfolio of technology programs GE Aerospace is developing and scaling to advance hypersonic capabilities, including high-temperature materials and high-temperature electronics.
These technologies are the product of more than a decade’s worth of direct hypersonic-related efforts advanced by GE Aerospace Research and several decades of developments for its GE Aerospace engine business in key areas like high-temperature ceramic matrix composites (CMCs), silicon carbide power electronics, additive technologies, and advanced thermal management.
“As the aerospace sector sets its sight on the future of hypersonics, GE Aerospace is well positioned with the right capabilities, experience, and scale to be a leader in driving new developments for our customers,” said Amy Gowder, President and CEO, GE Aerospace, Defense & Systems.
“The highly successful demonstration of a DMRJ with RDC is an outgrowth of our 10+ years of RDC work, including the strategic acquisition of Innoveering that has brought leading technologies and experience in hypersonic propulsion and ramjets.”
A typical air-breathing DMRJ propulsion system can only begin operating when the vehicle achieves supersonic speeds of greater than Mach 3. GE Aerospace engineers are working on a rotating detonation-enabled dual mode ramjet that is capable of operating at lower Mach numbers, enabling the flight vehicle to operate more efficiently and achieve longer range.
