Study of basic physical processes in liquid and solid rocket propulsion

Abstract

A process model was developed to assess the suitability of new/modified technologies and subsystems for application to commercial launch vehicles. Suitability is measured in terms of cost, safety, and environmental impact. Cost is related to recurring production and operational cost per flight, amortization of non-recurring development costs, 'effective' cost of difference in payload capability, and the cost of unreliability. The process is also applicable for assessing technologies and subsystems for application to other launch vehicles. The process will enable a comprehensive systems engineering approach to assess the potential of technologies and subsystems for launch vehicle applications and to provide documentation of the results for application to technology planning for the future.
