Yuzhnoye solid rocket engine. RT-23 early models stage I. Out of Production. The case-bound T9-BK composite solid propellant charge had a star shape channel. The case was of organic fibre-wound plastic material.

The central stationary control nozzle partially intruded into the combustion chamber. Steering was accomplished by fluid injection into the hot chamber gas into the supersonic nozzle section via eight stem valves. The thrust vector control system ensured control in all three axes (pitch, roll, yaw). The motor had an advantage over engines with other types of thrust vector control systems with limited aft bay volume.

Application: RT-23 early models stage I.

Characteristics

Thrust (sl): 220,000 kgf.

Status: Out of Production.
Height: 8.40 m (27.50 ft).
Diameter: 2.40 m (7.80 ft).
Thrust: 2,353.00 kN (528,975 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.
