مرروری بر روش‌های تولید آمونیوم دی‌نیترآمید ((ADN و توسعه کاربردی آن در پیشرانش فضایی
Owing to the prime importance of ammonium dinitramide (ADN) as an oxidizer in solid propellants, its synthesis has received a great amount of interest. There have been several new and innovative synthesis routes developed by researcher’s worldwide. Liquid-fuel rockets consist of a fuel and oxygen (or other oxidizer) in liquid state. These fractals are already being combined together or combined...
متن کاملSynthesis of Ammonium Dinitramide by Nitration of Potassium and Ammonium Sulfamate. The Effect of Sulfamate Conterion on ADN Purity
Nitration of potassium sulphamate was carried out using a mixture of sulphuric and nitric acid at -30 °C. The reaction time was optimized at the mole ratio of sulphuric to nitric acid of (1:3.5). The difference in product yield by changing the potassium to ammonium sulphamate was studied throughly. It was found that both the yield and purity of the product is better starting with potassium ...
متن کاملMechanism and kinetics for ammonium dinitramide (ADN) sublimation: a first-principles study.
The mechanism for sublimation of NH(4)N(NO(2))(2) (ADN) has been investigated quantum-mechanically with generalized gradient approximation plane-wave density functional theory calculations; the solid surface is represented by a slab model and the periodic boundary conditions are applied. The calculated lattice constants for the bulk ADN, which were found to consist of NH(4)(+)[ON(O)NNO(2)](-) u...

متن کاملComparing Direct and Indirect Thrust Measurements from Passively Fed and Highly Ionic Electrospray Thrusters
Highly ionic beams of several hundred μA per cm 2 have been measured from porous glass ionic liquid electrospray sources fabricated using a conventional mill. The thrust output from three prototype devices, two emitting the ionic liquid EMI-Im and one emitting EMI-BF 4, was measured directly using a precise balance. Thrusts up to 50 μN were measured when emitting EMI-Im in a bipolar, alternatin...
