- Abstract
A completely reusable orbital launch system has yet to be fully realized and the conception, development and successful operation of such systems remains a significant and ever-present challenge for companies in the space industry. However, advancements in materials, engine, and aerospace technology suggest that for future launch systems reusability is becoming increasingly feasible. This paper presents a comparison of the innovation and investment strategies of various companies which are currently in the development stage of various reusable launch vehicles in the commercial sector. Firstly, selected new technologies and developments are compared, including innovative engine designs, propellant and materials uses, multi-stage systems, and vehicle types. Secondly, to assess the investments undertaken by relevant organizations, the results of a parametric cost estimation are presented in order to assess the development and production costs of the compared vehicles (including those of Bristol Spaceplanes, Reaction Engines, and Blue Origin). Finally, after quantification of the different investments, an analysis of the respective investment strategies is presented and conclusions are drawn.
