Highly Controllable Solid Propellant and Rocket Motor Propulsion Technology

Over the last 15 years controllable solid propulsion development has aggressively pursued and demonstrated technologies that effectively emulate liquid propulsion performance. Future development is required that focuses on systems with longer operation time, higher thrust, faster thruster response times and greater impulse management. A key enabling technology to achieving these attributes is the development of a robust and repeatable ignition/re-ignition system. This technology enables a controllable solid propulsion system to manage packaged impulse, through reliable extinguishments and re-ignitions, delivering increased impulse flexibility. During our Phase 1 effort, advanced extinguishable solid DACS and booster system architectures are identified and traded using multiple advanced ignition/re-ignition candidate technologies. The result is an ignition/re-ignition system conceptual design that increases controllable solid propulsion performance and mission flexibility
