Positive experience of studying modifications of the UR-100 missile

Sequential study of modifications of Intercontinental Ballistic Missiles (ICBM) UR-100 (SS-11 Sego) introduces students as a designer meet the requirements of the military to increase the power of the combat impact of missile weapons at a relatively low cost. The UR-100 missile was created in the mid-60s of the last century. For that time, the rocket was the best in her class. Successes in the field of creation of control systems, improvement of propulsion systems allowed even before the adoption of the UR-100 into service to begin its modernization. It was replaced by its modifications UR-100K, UR-100N, UR-100N ITTC (SS-17 Spanker).. All these missiles were created in the Central Design Bureau of Mechanical Engineering under the leadership of V. N. Chelomey. The study of various modifications of missiles allows students to acquaint with modern trends in the design of missiles. Special attention is paid to the "wafer" design of tanks, the development of combined bottoms, issues of ensuring tightness. The advantages and disadvantages of liquid rocket engines with a turbo pump system of fuel components supply, both without after-burning of the generator gas and with afterburning, are considered. The systems and methods providing fast start of liquid rocket engines are considered. The problems encountered during the development of the last two modifications and their elimination acquaint students with the dynamic stability of liquid-propellant rockets. The transition from one version of the UR-100 to another allows students to demonstrate what design changes make it possible to consistently increase the range, accuracy and significantly expand the capabilities of each subsequent modification while minimizing costs.
