| Abstract [eng] |
The objective of the research is to analysis the external ballistic characteristics of middle range rocket target with constant thrust and varying rocket motor operating time. The main requirement is to achieve the rocket target with horizontal distance (range) of 20 km and vertical distance (altitude) of 10 km. The rocket motor to be used should be RM-12K designed and built by Kaunas University of technology, Institute of Defense technology. This motor can produce up to 12 kN thrust for 3.2 seconds. To achieve the goal, computational model is designed using SOLID WORKS student edition and numerical modelling for ballistic analysis is carried out in MATLAB Simulink. In this research three different configuration is used to achieve the requirement. First, one motor is ignited for 3.2 seconds to produce 12 kN thrust. In second test all four motors are ignited together for 3.2 seconds which produce 48 kN thrust force. In third configuration two motor is used for 3.2 seconds to produce 24 kN and after the burnout, second two motor is ignited for 3.2 seconds. Comparative analysis of three different configuration shows that the requirement of 20 km range and 10 km altitude was realized by using two plus two motors for 6.4 seconds of operational time. |
