Specific impulse estimation method on the microthruster example

Reporter: Кискин А.Б.

Within the framework of the project on the investigation of specific impulse losses of microthrusters the direct measurements of specific impulse were done. It was made the specific impulse estimation based on recoil force measurements of solid propellant samples in addition. Composite propellant with 2% of Al was used in experiments. Cases of microthrusters were fabricated in the form of a cylinder from melted quartz. Inner volume of chamber was about 0.07 cm3. Specific impulse measurements were performed using recoil force transducer. The same transducer was used in the experiments on combustion of solid propellant samples at the elevated pressure. The data obtained have allowed estimating the ratio of combustion temperature of gas products to their molecular weight that, in turn, has allowed calculating (the value of) specific impulse.
This research being conducted within framework of the Russian Foundation for Basic Research (RFBR) Progect 06-08-01298-а.
