Dynamics and Scales of Stabilized and Rotating Oblique Detonation Waves for Hypersonic and Space Propulsion
Abstract
There is a national priority in achieving ultra-high-speed flight at hypersonic speeds. Advanced hypersonic propulsion systems are needed to maintain the technological superiority of the U.S. Air Force relative to the growing technological threat from adversaries. Detonations, shock-coupled with intense high-speed turbulent compressible reactions, provide intense energy conversion mechanism for hypersonic and space propulsion for missiles, rockets, and aircraft engines. The scientific objective of the proposed research is to explore the dynamics and scales of standing and rotating oblique detonation waves. The proposed research is motivated by recent work that stabilized oblique detonations for hypersonic propulsion. The proposed research program will establish the fundamental limits of high-speed detonations and shock-coupled reactions and will establish a fundamental understanding of the mechanism by which the unconfined environment and increase in detonation strength modifies the propagation dynamics of oblique detonation waves. The investigation will follow a tightly integrated experimental approach that will experimentally explore the standing and rotating oblique detonations in a unique hypersonic reacting facility (HyperReact) facility. HyperReact allows the detailed exploration of the detonation dynamics in previously inaccessible regimes at extreme Mach numbers with high-speed, high-resolution advanced laser diagnostics. This understanding is critical and timely to accelerate the understanding and controlling of this game-changing ultra-high-speed oblique detonation phenomenon and has the potential to revolutionize hypersonic propulsion for atmospheric and space flights.
