Abstract India as a spacefaring nation has been stressing on low-cost access to space as a major objective while developing propulsion modules for launch vehicles. This chapter dwells in detail the history of solid motors developed for rockets and launch vehicles by India. India’s maturity in design, development and operationalising large solid boosters for launch vehicle application is also given. The development of S200 solid booster for GSLV MK III, the new generation vehicle, has been brought out in detail. A number of challenges like realisation of long S200 motor case segments to minimise segment joints and thereby reducing the inerts, casting of 100 T propellant within the penetrometric pot life of HTPB-TDI propellant, handling and transportation of heavy S200 case segments, infrastructure build-up towards propellant processing and assembly and testing of S200 motor and flex nozzle system are discussed in detail. S200 pyrogen igniter development and propellant properties evaluation are brought out along with the demonstration of thrust differential seen in the flight performance of the two S200 strap-on motors in LVM3-X mission. Pressure oscillations seen in S200 motor are compared with large segmented motors like P-230, RSRM etc., and elimination of thrust oscillation isolation system has been validated in LVM3-X mission. Future road map envisaged for solid motor system development is addressed with a focus to reduce the inerts in solid propulsion system.
