Field notes
The page specifies HTPB-AP and ionic liquids among the propellants, gives a 5–10 ns pulse-rise-time range, and reports an approximately 30 ms off-to-on transition between two consecutive video frames. It identifies the founders’ USC research connection and says foundational work received DARPA and Air Force Office of Scientific Research support. The 3- and 6-inch motors remain development steps, not capabilities demonstrated on the page.
