We are working closely with the Army Research Laboratory on a number of different scientific issues including basic fuel kinetics at low temperatures, laser diagnostics of turbulent flames in gas turbine laboratory combustors, and ignition events in high altitude conditions. The collaboration is mainly through the Center for UAS Propulsion Systems (CUP), for which we are the lead institution.
