Selection of Favorite Reusable Launch Vehicle Concepts by Using the Method of Pairwise Comparison
Selection of Favorite Reusable Launch Vehicle Concepts by using the Method of Pairwise Comparison Robert A. Goehlich Keio University, Department of System Design Engineering, Ohkami Laboratory, 3-14-1 Hiyoshi, Kohoku-ku, Yokohama 223-8522, JAPAN, Mobile: +81-90-1767-1667, Fax: +81-45-566-1778 email: [email protected], Internet: www.Robert-Goehlich.de Abstract The attempt of this paper is to select promising Reusable Launch Vehicle (RLV) concepts by using a formal evaluation procedure. The vehicle system is divided into design features. Every design feature can have alternative characteristics. All combinations of design features and characteristics are compared pairwise with each other with respect to relative importance for a feasible vehicle concept as seen from technical, economic, and political aspects. This valuation process leads to a ranked list of design features for suborbital and orbital applications. The result is a theoretical optimized suborbital and orbital vehicle each. The method of pairwise comparison allows to determine not only ranking but also assessing the relative weight of each feature compared to others. Keywords: Pairwise Comparison, Reusable Launch Vehicle, Space Tourism Introduction The potential for an introduction of reusable launch vehicles is derived from an expected increasing demand for transportation of passengers in the decades to come. The assumed future satellite market does not justify to operate reusable launch vehicles only for satellites due to a low launch rate. Finding feasible vehicle concepts, which satisfy operator’s, passenger’s, and public’s needs, will be a challenging task. Since it is not possible to satisfy all space tourism markets by one vehicle, different vehicles that are capable to serve one particular segment (suborbital or orbital) are needed. -

Interim Report Design, Cost, and Performance Analyses Executive Summary This report, jointly sponsored by the Defense Advanced Research Projects Agency (DARPA) and the National Aeronautics and Space Administration (NASA), is the result of a comprehensive study to explore the trade space of horizontal launch system concepts and identify potential near- and mid-term launch system concepts that are capable of delivering approximately 15,000 lbs to low Earth orbit. The Horizontal Launch Study (HLS) has produced a set of launch system concepts that meet this criterion and has identified potential subsonic flight test demonstrators. Based on the results of this study, DARPA has initiated a new program to explore horizontal launch concepts in more depth and to develop, build, and fly a flight test demonstrator that is on the path to reduce development risks for an operational horizontal take-off space launch system. The intent of this interim report is to extract salient results from the in-process HLS final report that will aid the potential proposers of the DARPA Airborne Launch Assist Space Access (ALASA) program. Near-term results are presented for a range of subsonic system concepts selected for their availability and relatively low development costs. This interim report provides an overview of the study background and assumptions, idealized concepts, point design concepts, and flight test demonstrator concepts. The final report, to be published later this year, will address more details of the study processes, a broader trade space matrix including concepts at higher speed regimes, operational analyses, benefits of targeted technology investments, expanded information on models, and detailed appendices and references. -

Increasing Launch Rate and Payload Capabilities
Aerial Launch Vehicles: Increasing Launch Rate and Payload Capabilities Yves Tscheuschner1 and Alec B. Devereaux2 University of Colorado, Boulder, Colorado Two of man's greatest achievements have been the first flight at Kitty Hawk and pushing into the final frontier that is space. Air launch systems aim to combine these great achievements into a revolutionary way to deliver satellites, cargo and eventually people into space. Launching from an aircraft has many advantages, including the ability to launch at any inclination and from above bad weather, which could delay ground launches. While many concepts for launching rockets from an airplane have been developed, very few have made it past the drawing board. Only the Pegasus and, to a lesser extent, SpaceShipOne have truly shown the feasibility of such a system. However, a recent push for rapid, small payload to orbit launches by the military and a general need for cheaper, heavy lift options are leading to an increasing interest in air launch methods. In order for the efficiency and flexibility of the system to be realized, however, additional funding and research are necessary. Nomenclature ALASA = airborne launch assist space access ALS = air launch system DARPA = defense advanced research project agency LEO = low Earth orbit LOX = liquid oxygen RP-1 = rocket propellant 1 MAKS = Russian air launch system MECO = main engine cutoff SS1 = space ship one SS2 = space ship two I. Introduction W hat typically comes to mind when considering launching people or satellites to space are the towering rocket poised on the launch pad.

Design Evolution and AHP-Based Historiography of Lifting Reentry Vehicle Space Programs
AIAA 2016-5319 AIAA SPACE Forum 13 - 16 September 2016, Long Beach, California AIAA SPACE 2016 Design Evolution and AHP-based Historiography of Lifting Reentry Vehicle Space Programs Loveneesh Rana∗ and Bernd Chudoba y University of Texas at Arlington, TX-76019-0018 The term \Historiography" is defined as the writing of history based on the critical examination of sources. In the context of space access systems, a considerable body of lit- erature has been published addressing the history of lifting-reentry vehicle(LRV) research. Many technical papers and books have surveyed legacy research case studies, technology development projects and vehicle development programs to document the evolution of hy- personic vehicle design knowledge gained from the early 1950s onwards. However, these accounts tend to be subjective and qualitative in their discussion of the significance and level of progress made. Even though the information addressed in these surveys is consid- ered crucial, it may lack qualitative or quantitative organization for consistently measuring the contribution of an individual program. The goal of this study is to provide an anatomy aimed at addressing and quantifying the contribution of legacy programs towards the evolution of the hypersonic knowledge base. This paper applies quantified analysis to legacy lifting-reentry vehicle programs, aimed at comprehensively capturing the evolution of LRV hypersonic knowledge base. Beginning with an overview of literature surveys focusing on hypersonic research programs, a com- prehensive list of LRV programs, starting from the 1933 Silvervogel to the 2015 Dream Chaser, is assembled. These case-studies are assessed on the basis of contribution made towards major hypersonic disciplines. -
