Star 26C


Thiokol solid rocket engine. 35 kN. In Production. Isp=272s. Upper stage motor used the titanium alloy case and nozzle attachment ring of the STAR 26B design to provide high propellant mass fraction and was insulated for high-spin-rate applications.

Upper stage motor employs the titanium alloy case and nozzle attachment ring of the STAR 26B design to provide high propellant mass fraction and is insulated for high-spin-rate applications. The motor is used as an upper stage in the Sandia National Laboratories Strypi IV vehicle and in the U.S. Army's Designated Optical Tracker vehicle. Total impulse 63,389 kgf-s. Propellant mass fraction 0.88.

Associated Propellants
  • Solid Solid propellants have the fuel and oxidiser embedded in a rubbery matrix. They were developed to a high degree of perfection in the United States in the 1950's and 1960's. In Russia, development was slower, due to a lack of technical leadership in the area and rail handling problems. Solid propellants have the fuel and oxidiser embedded in a rubbery matrix.
