S.2 Educational Objectives From this chapter the student will learn: Propulsion system selection criteria - 2 - Primary selection criteria based on propulsion system performances: - System-specific Impulse, Issp - overall propulsion system mass fraction The ‘Issp software program’ for propulsion system performance simulation An outline of the potential evolution of future advanced spacecraft propulsion systems
- 3 - S.3 Propulsion System Selection In the selection process, the most fundamental criterion for the propulsion system to be selected is its achievement of the mission impulse and velocity increment ∆v requirements. Therefore, an important consideration for the selection of a suitable propulsion system is the trade-off between its velocity increment capability and propulsion system mass. The mass of propulsion systems can be determined with help of the overall Propulsion System Mass Fraction (see Chapter 2) The Curves of mPS/mS/C, plotted as a function of ∆v for different actual spacecraft propulsion system designs with typical values of Isp (ve) and Issp, give the first and most important indication for the selection of propulsion systems. For a more detailed performance evaluation, the software program “Issp” can be used. It is based on the evaluation of the ‘System-specific Impulse’, Issp. It can be downloaded from Swedish Space Corporation Web Site. When suitable spacecraft auxiliary propulsion systems are selected, a refinement of the selection is carried out. This process takes into consideration additional parameters such as cost, complexity, operability and reliability of the system (more selection criteria). This table summarizes advantages and disadvantages as well as the basic characteristics of different propulsion systems.
