Nasa X-15 Program
5 24,132 6 9 NASA X-15 PROGRAM By: T.D. Barnes - NASA Contractor - 1960s NASA contractors for the X-15 program were Bendix Field Engineering followed by Unitec, Inc. The NASA High Range Tracking stations were located at Ely and Beatty Nevada with main control being at Dryden/Edwards AFB in California. Personnel at the tracking stations consisted of a Station Manager, a Technical Advisor, and field engineers for the Mod-2 Radar, Data Transmission System, Communications, Telemetry, and Plant Maintenance/Generators. NASA had a site monitor at each tracking station to monitor our contractor operations. Though supporting flights of the X-15 was their main objective, they also participated in flights of the XB-70, the three Lifting Bodies, experimental Lunar Landing vehicles, and an occasional A-12/YF-12/SR-71 Blackbird flight. On mission days a NASA van picked up each member of the crew at their residence for the 4:20 a.m. trip to the tracking station 18 miles North of Beatty on the Tonopah Highway. Upon arrival each performed preflight calibrations and setup of their various systems. The liftoff of the B-52, with the X-15 tucked beneath its wing, seldom occurred after 9:00 a.m. due to the heat effect of the Mojave Desert making it difficult for the planes to acquire altitude. At approximately 0800 hours two pilots from Dryden would proceed uprange to evaluate the condition of the dry lake beds in the event of an emergency landing of the X-15 (always buzzing our station on the way up and back). -

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. -

DANIELA KINCOVÁ AUTHOR VEDOUCÍ PRÁCE Ing. RÓBERT ©O©OVIÈKA, Ph.D. SUPERVISOR BRNO 2015 Abstrakt Tato práce se zabývá problematikou zavedení a provozu nadzvukových business jetù. V dnešní době se v civilní letecké pøepravě, po ukončení provozu Concordu, žádná nadzvuková letadla nevyskytují. V dnešní době existuje mnoho projektù a organizací, které se zabý- vají znovuzavedením nadzvukových letounù do civilního letectví a soustředí se pøevážně na business jety. Hlavní otázkou je, zda je vùbec vhodné, èi rozumné se k tomu typu dopravy znovu vracet. Existuje hodně problémù, které toto komplikují. Tyto letouny způsobují příliš velký hluk, mají obrovskou spotøebu paliva a musí øe¹it nadměrné emise, létají ve vysokých výškách ve kterých mùže docházet k problémùm s pøetlakováním kabiny, navi- gací, radioaktivním zářením apod. Navíc zákaz supersonických letù nad pevninou letové cesty omezuje a prodlužuje. Současně vznikající projekty navíc nedosahují tak velkého doletu jako klasické moderní bussjety, což zpùsobuje, že se nadzvukové business jety se na delších tratích stávají neefektivní. I pøes tyto problémy, je víceméně jisté, že k zavedení nadzvukových business jetù dojde během následujících 10 - 15 let, i kdyby to měla být jen otázka jisté prestiže velmi bohatých lidí. Summary This thesis is dealing with problematic about launching and operating supersonic business jets. Nowadays, after Concorde retirement, there are no more any supersonic aircrafts in civil transport system. -
Planners for Hypersonic Spaceliner Craft Propose a 50 Year Timeline 28 January 2013, by Bob Yirka
Planners for hypersonic SpaceLiner craft propose a 50 year timeline 28 January 2013, by Bob Yirka destination. As the craft glides, it would reach speeds of up to 15,000 mph, which would account for the short travel time. But such plans also pose a problem for engineers as the vehicle would experience the same heat buildup as space reentry vehicles. For that reason, the design of the craft itself is still a work in progress. Engineers are analyzing the results of FAST20XX, a joint European project that has been studying the types of high speed craft that might carry people in the not so distant future. They will also no doubt be consulting with NASA on lessons learned from the space shuttle program. Credit: DLR-SART The SpaceLiner project carries with it many unknowns – foremost among them perhaps, is whether enough people will be willing to pay the (Phys.org)—Martin Sippel, project coordinator for expected several hundred thousand dollar cost of a the SpaceLiner project has announced that the single ride.

The Development of the Spaceliner Concept and Its Latest Progress
4TH CSA-IAA CONFERENCE ON ADVANCED SPACE TECHNOLOGY The Development of the SpaceLiner Concept and its Latest Progress Tobias Schwanekamp, Carola Bauer, Alexander Kopp [email protected] Tel. +49 (0) 421 24420-231, Fax. +49 (0) 421 24420-150 German Aerospace Center (DLR), Institute of Space Systems, Space Launcher System Analysis (SART), 28359 Bremen, Germany A visionary, ultrafast passenger transportation concept, proposed as the SpaceLiner, is developed by the Space Launcher System Analysis department of the German Aerospace Center DLR. Based on rocket propulsion this two stage RLV should be capable to carry about 50 passengers over ultra-long-haul distances within a fractional amount of time needed for common long-distance flights. Since the SpaceLiner has been proposed for the first time in 2005, the concept is subject to an iterative process of development. Several configuration trade-offs have been performed in order to support the definition of the next reference configuration. This paper gives a summary of the main enhancements and the knowledge gained within the preliminary design phase of the SpaceLiner orbiter stage. As the Orbiter volplanes along the major part of the hypersonic trajectory, the glide ratio is the most significant driving parameter to obtain maximum possible ranges. Thus the main focus of the investigations is on the development of an aerodynamic and aerothermodynamic shape design as well as on various system and environmental aspects or rather operating conditions which have an impact on the aerodynamic -
