| Popis: | Solid rockets are required ‘environmentally friendly’, ‘high performance’, and ‘low cost’ at the present day. Ammonium dinitramide (ADN) is a new oxidizer for the solid propellants. Ammonium dinitramide is the environmentally friendly oxidizer because ADN has no halogen. Ammonium dinitramide based propellants have higher performance than ammonium perchlorate (AP) based propellants. However, ADN is more expensive than AP. Therefore, we suggested ADN/ammonium nitrate (AN) based propellants. Ammonium nitrate is the very inexpensive oxidizer which has no halogen. The solid propellants are added the metal particles in order to achieve the high performance. However, ignition and combustion characteristics of the metal particles contained ADN/AN based propellants are not investigated. In this research, we investigated reaction and ignition characteristics of magnalium (Mg-Al) particles in ADN / AN. As a result, it is considered that Mg-Al particles reacted with the decomposition products of ADN/AN. Ignition delay time of Mg-Al particles increased with increasing the concentration of AN. Ignition delay time of Mg-Al particles increased at the concentration of AN between 20 mass% and 60 mass%. 形態: カラー図版あり Physical characteristics: Original contains color illustrations 資料番号: AA0061907003 レポート番号: JAXA-RR-12-005 |
