Mission
Centered at the intersection of materials development and energetic materials combustion and propulsion, the Energetic Materials Combustion Lab is a multidisciplinary laboratory with the aim to study the combustion of energetic materials and to develop new energetic materials possessing dynamic control, improved performance, and improved environmental and toxicological characteristics. We are a world-leading research group in the area of SMART Energetic Materials--those capable of actively-controlled energy output for the development of new capabilities. Our goals are to explore the possibility of new energetic material functionality through both fundamentally and application-driven research, to train future leaders in energetics, and to further the scientific goals we and our partners mutually hold.

We have just been notified from the University Consortium for Applied Hypersonics of selection of our proposal, "Microwave active control of propellant burning rate through addition of wires," for the development and demonstration of a high thrust, high mass fraction, electromagnetically throttleable solid motor, with our partners, NSWC-Crane (Drs. Stuart Barkley and Adam Lawrence) and NAWS China Lake (Drs. Justin Lajoie and Andrew Demko). We are all very excited for this project and grateful for the opportunity!

Congratulations Dr. Justin Lajoie for the acceptance of the paper, "On-Demand Microwave Growth of Energetic Material Porosity: Void Formation via a Dielectric Loss Phase Change Binder Additive for Propellant Burning Rate Control," in PEP. In-situ, porosity growth inside of an energetic has potential in propellants and beyond!
Right top: Image sequence of microwave-mediated growth of monodisperse porosity within a HTPB propellant binder. Right bottom: Effect of microwave-grown porosity on propellant burning rate. Without microwave (black); with microwave pre-treatment (pink). Linear burning rates (solid) and mass burning rates (dashed) are shown.

Congratulations to Ph.D. candidate Justin Lajoie for publication of his paper on combined rheological, mechanical, and ballistic properties of a 3D printed propellant formulation, showing 3D printed propellants can far surpass traditionally manufactured composites in mechanical performance. Much still to do in 3D printed propellants, however before they are cast replacements.
