Abstract: The Scorpius low-cost launch vehicle architecture greatly reduces the cost of space access due to its emphasis on designing specifically for low total life cycle cost. Due to its simplicity, a pressure-fed launch vehicle is low in cost compared with pump-fed...
Abstract: In the Microcosm Responsive Launch Systems model, a key requirement is that the launch vehicle be essentially a commodity, built to inventory, and ready to go whenever needed, much like cruise missiles or rental cars. This, in turn, implies the need for low...
Abstract: Microcosm and Sierra Engineering have been developing a series of low-cost pressure fed LOX/kerosene engines to power the Scorpius® family of launch vehicles. This paper focuses on the design, fabrication and testing of a 20K lbf O-F-O triplet injector with...
Abstract: “Responsive space” has substantial benefit in terms of both flexibility to meet real-time needs and assured space access. However, creating responsive space requires a new paradigm for space launch systems, launch operations, and the space systems...
Abstract: This paper illustrates the cost advantage of a space transportation system that uses pressure-fed technology and describes pertinent aspects of scaling the propulsion technology for light-lift through medium- and heavy-lift vehicles. Microcosm has used this...
