A miniature solid propellant rocket motor [PDF]
33rd Joint Propulsion Conference and Exhibit, 1997 A miniature solid-propellant rocket motor has been developed to impart a specific motion to an object deployed in space. This rocket motor effectively eliminated the need for a cold-gas thruster system or mechanical spin-up system. A low-energy igniter, an XMC4397, employing a semiconductor bridge was used to ignite the rocket motor.

Grain Configuration of Solid Rocket Motor [PDF]
Graduate Research in Engineering and Technology, 2022 The solid rocket motor upper stage for a space launch vehicle is a more efficient propulsion technology than the liquid rocket motor upper stage. Its grain design has the potential to be crucial in terms of lowering inert mass by adopting improved volume efficiency with the lowest practicable sliver size while keeping maximum strength.

Combustion Modeling in Solid Rocket Motor Plumes [PDF]
, 2019 The thermo-chemistry of plumes emanating from solid rocket motors (SRM) is strongly influenced by hydrogen/oxygen/chlorine chemistry. These after-burning reactions have a significant impact onto the infrared signature, as well as on chemical and thermal loads within the propulsion system.

CD8+ T cell memory is sustained in mice by hepatic stellate cells
Hepatology, EarlyView., 2022 HSC role in memory CD8+ T cell maintenance. Abstract Background and Aims Long‐lasting immunological memory is the ultimate goal of vaccination. Homeostatic maintenance of memory CD8+ cytotoxic T cells (MemCD8TCs) is thought to be mediated by IL‐15/IL‐15R heterodimer (15HD)‐expressing myeloid cells.
