Yuzhnoye. Tsurilnikov solid rocket engine. RT-23 stage II. Out of Production. The case-bound START composite solid propellant charge had a cylindrical-conical umbrella shape channel. The case was of organic fibre-wound plastic material.

The gimbaled engine nozzle partially intruded into the combustion chamber and had a nozzle extension for improved performance. Versions of the motor seem to have been manufactured by both Tsurilnikov in Russia and Yuzhnoye in the Ukraine. Length with the nozzle extended was 6.7 m.

Application: RT-23 stage II.

Status: Out of Production.
Height: 5.90 m (19.30 ft).
Diameter: 2.40 m (7.80 ft).
Thrust: 1,470.00 kN (330,460 lbf).
First Launch: 1976-85.

Associated Launch Vehicles
  • RT-23 Ukrainian intercontinental ballistic missile. The only rail-based ICBM ever deployed. Developed by Yuzhnoye in the Ukraine was protracted, but understandable given the huge technical challenges. Twelve years of design and testing was followed by deployment from 1988. All were retired by 2003. More...

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.
