항공무장 안정성 향상을 위한 날개 전개 구동기의 작동로직 설계 = Deployment Actuator Logic Design for Enhancing Aircraft Armament Stability

다국어 초록 (Multilingual Abstract)

For the high reliability of guidance weapon, it is important to maintain the stable supply voltage for guidancesystem while the bomb is gliding. However, the DC motor drive for guidance control in the low temperature canlead to the critical voltage drop due to a large inrush current.
In this paper, we propose the wing deployment logic design to enhance the guidance system stability. To derivethe stable drive logic based on PWM, we controlled the duty cycles for input voltage of DC motor in lowtemperature. The initial duty cycle was set to 40 % to relieve the inrush current. Moreover, the proper time,which is less than 1 second for controlling duty cycles, was determined by the iterative wing deployments ofguidance kit. Finally, the validity of proposed logic was confirmed from the result the maximum voltage drop forthe wing deployment was decreased by 23 %.
