The presence of the erosive burning effect during operation a solid rocket motor (SRM) is one most important factors affecting proper motor. To solve effects operating process under burning, synthesis algorithm based on actual CT images proposed to combine Level-set (LS) method with minimum distance function (MDF) for simulation surface regression grain burning. Hamilton–Jacobi control equation...

Low-thrust long-burn-time solid rocket motors may be useful as propulsion for small, fast, uncrewed aerial vehicles. These require a slow-burning propellant that can operate at unusually low chamber pressures (0.3–2 MPa). Slow-burn propellants were developed using ammonium perchlorate oxidizer and the burn rate suppressant oxamide. By varying amount of oxamide (from 0 to 20%), rates from 4 (at ...
