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. -

Dogfight History
Dogfight A dogfight or dog fight is a common term used to describe close-range aerial combat between military aircraft. The term originated during World War I, and probably derives from the preferred fighter tactic of positioning one's aircraft behind the enemy aircraft. From this position, a pilot could fire his guns on the enemy without having to lead the target, and the enemy aircraft could not effectively fire back. The term came into existence because two women fighting is called a catfight, and all early fighter pilots were men, hence dogfight. This subsequently obtained its revised folk etymology about two dogs chasing each other's tails.[citation needed] Modern terminology for aerial combat between aircraft is air-to-air combat and air combat maneuvering, or ACM. F-22 Raptors over Utah in their first official deployment, Oct. 2005, simulating a dogfight. History World War I Dogfighting emerged in World War I. Aircraft were initially used as mobile observation vehicles and early pilots gave little thought to aerial combat—enemy pilots at first simply exchanged waves. Intrepid pilots decided to interfere with enemy reconnaissance by improvised means, including throwing bricks, grenades and sometimes rope, which they hoped would entangle the enemy plane's propeller. This progressed to pilots firing hand-held guns at enemy planes. Once machine guns were mounted to the plane, either in a turret or higher on the wings of early biplanes, the era of air combat began. The Germans acquired an early air superiority due to the invention of synchronization gear in 1915. During the first part of the war there was no established tactical doctrine for air-to-air combat. -

ABSTRACT: Special operations are conducted more than ever in modern warfare. Since the 1980s they have developed and grown in numbers. But with more attempts of operations and bigger numbers, comes failures. One of these failures is operation Red Wings where a unit of US Navy SEALs at- tempted a recognisance and raid operation in the Hindu Kush. The purpose of this paper was to see how that failure could be analysed from an existing theory of Special operations. This was to ensure that other failures can be avoided but mainly to understand what really happened on that mountain in 2005. The method used was a case study of a single case to give an answer with quality and depth. The study found that Mcravens theory and principles of how to succeed a special operation was not applied during the operation. The case of operation Red Wings showed remarkable valour and motivation, but also lacked severely when it came to simplicity, surprise, and speed.
