Abstract
The University of Central Florida invention is a supersonic oblique rotating detonation wave engine (SORDE) and methods for generating supersonic to hypersonic propulsion. The innovation provides a pathway for developing hypersonic propulsion technology for atmospheric and space flights (Mach 1.2 to 6) as well as advanced power systems. As an example, the invention could be used to develop technologies that enable high-speed flight through Earth’s atmosphere and for entering/leaving other planetary atmospheres.
Technical Details: The invention comprises a supersonic oblique rotating detonation wave engine (SORDE), along with systems and methods for generating a SORDE wave. To produce and sustain a SORDE wave, the engine configuration enables the injection of fuel at supersonic speeds into an inlet air flow between Mach 1 and Mach 7. The technology also includes injecting fuel into the inlet air to establish a fuel-air equivalence ratio of 0.2 to 2.5. Some embodiments can include the following:
- A fuel injector with multiple ports, each with a diameter of about 0.010-0.040 inches
- An annular wedge disposed in or upstream of the detonation chamber with an angle of about 5-40 degrees relative to a longitudinal axis of the engine
- A cylindrical center body disposed in or upstream of the detonation chamber
Partnering Opportunity: The research team is seeking partners for licensing, research collaboration, or both.
Stage of Development: Prototype available.
