Many of high energy material (HEMs) compose without halogen atoms. Additionally, the propellants that used HEMs indicate high theoretical propulsion performance through the calculation. Ammonium dinitramide (ADN) is one of the candidates of the new oxidizer for the advanced solid propellant. However, the combustion characteristics of ADN should be understood deeply for the practical use. In this study, the burning rate characteristics of the ADN/AN mixture pellet were investigated to understand the effects of AN mass ratio in the mixture. The results show that the burning rate of the ADN/AN pellet was decreased with increasing the mass ratio of AN in the pellet. Additionally, the burning rate of ADN/AN pellet (AN mass ratio, 20 mass%) was decreased 40 % compared with ADN at 2 MPa., 形態: 図版あり, Physical characteristics: Original contains illustrations, 資料番号: AA0062089004, レポート番号: JAXA-RR-13-009}, title = {ADN/AN の燃焼速度特性}, year = {2014} }
