Kim, Ju Won; Baek, Seungkwan; Jung, YeonSoo; Yoon, Wonjae; Ban, Hong Seop; Kwon, Sejin published the artcile< An alternative ADN based monopropellant mixed with tetraglyme>, COA of Formula: C19H34O2, the main research area is ammonium dinitramide water tetraglyme.
In this study, a new monopropellant which consists of ammonium dinitramide (ADN) water solution and tetraethylene glycol di-Me ether (Tetraglyme) fuel is reported. The purpose of research was to improve the specific impulse and to compensate for the preheating temperature and vapor pressure of LMP-103S (63 wt% ADN, 14 wt% water, 18.4 wt% methanol, and 4.6 wt% ammonia). Methanol, ethanol, acetone, and glycerol were also used as the organic fuels to prepare the ADN based monopropellant with and without ammonia solution Further, the characteristic properties and performance of ADN based monopropellants were determined and compared with each other. The thermal properties and explosive power of those monopropellants were performed by using thermogravimetric anal. and differential scanning calorimetry (TGA-DSC) anal. and the blasting cap test, resp. The TGA-DSC anal. revealed that a catalyst active material was an important factor more than the flash point and auto-ignition temperature of fuel for the propellant’s preheating temperature The ADN based monopropellant mixed with tetraglyme exhibited a similar explosive power as with the LMP-103S. Moreover, the theor. vacuum specific impulse of the propellants mixed with tetraglyme was of 1-6% higher than the propellants with other fuels. Overall, ADN water solution blended with tetraglyme may be one of the promising fuel candidates for the satellite application.
