So I took the box home and went through the just doing the same thing over and over again, which is miscellaneous rocket parts when my first original idea probably why I had quit the rocketry phase of my life. came to me. How I exactly got there I don’t know.

Wallace§ SpaceWorks Engineering, Inc. (SEI), United States of America (USA) [email protected] Michael Kelly** SpaceWorks Engineering, Inc. (SEI), United States of America (USA) [email protected] ABSTRACT This paper examines the prospects for a successful regularly-scheduled high-speed package delivery service for high-priority intercontinental cargo, notionally to be undertaken within the next decade or two. The topic is investigated from both technical/vehicle design and economics/business case points-of-view. Potential cargo include packages and priority items for which there might be a premium paid for speed, particularly if door-to-door service can be achieved fully one business day earlier than the fastest scheduled offerings currently available in the industry. The paper introduces a preliminary traffic model for a future business case, highlighting key routes and estimated daily volumes and price expected. Candidate flight vehicles and requisite technologies are discussed, with a particular point-to-point reference concept being presented to serve as the basis for non-recurring and recurring service cost estimates. The overall business case is then investigated,

    A review of design issues specific to hypersonic flight vehicles (30/03/2016) D. Sziroczak, PhD, Cranfield University H. Smith, Professor, Cranfield University Abstract This paper provides an overview of the current technical issues and challenges associated with the design of hypersonic vehicles. Two distinct classes of vehicles are reviewed; Hypersonic Transports and Space Launchers, their common features and differences are examined. After a brief historical overview, the paper takes a multi- disciplinary approach to these vehicles, discusses various design aspects, and technical challenges. Operational issues are explored, including mission profiles, current and predicted markets, in addition to environmental effects and human factors. Technological issues are also reviewed, focusing on the three major challenge areas associated with these vehicles: aerothermodynamics, propulsion, and structures. In addition, matters of reliability and maintainability are also presented. The paper also reviews the certification and flight testing of these vehicles from a global perspective. Finally the current stakeholders in the field of hypersonic flight are presented, summarizing the active programs and promising concepts.

  • “Blackstar” Orbital Spaceplane System
    White Paper 03 April 2006 THOUGHTS ON THE POSSIBLE EXISTENCE OF THE “BLACKSTAR” ORBITAL SPACEPLANE SYSTEM 1 SPACE IS GO 1200 Ashwood Parkway, Suite 506 | Atlanta, GA | USA 30338 1+770.379.8000 | 1+770.379.8001 [Fax] | www.sei.aero | [email protected] GOALS OF THIS REVIEW The purported reusable, crewed two-stage-to-orbit flight system referred to as “Blackstar” is briefly technically assessed in the context of previous studies and technological developments. Leading features of its “SR-3” first-stage carrier aircraft and its “XOV” upper-stage spaceplane vehicle are commented upon. Several key design problem areas are pointed out, e.g., takeoff/landing gear, transonic acceleration, upper-stage propulsion. Finally, an attempt is made to positively envision the Blackstar vehicle system as being a technically feasible development, an exercise leading to the still unanswered question: did it exist? References: 1. Scott, W.B., Aviation Week & Space Technology, 6 March 2006, pp. 48-53 (three articles) 2. Jenkins, D.R. and Landis, T., North American XB-70A Valkyrie, Specialty Press, 2002 1 SPACE IS GO BACKGROUND The following is a summary of what is known about the Blackstar system based upon an article in the March 2006 issue of Aviation Week & Space Technology and taken from Wikipedia [www.wikipedia.org]. Source: Wikipedia [http://en.wikipedia.org/wiki/Blackstar_(spaceplane)] Blackstar is the reported codename of a secret United States orbital spaceplane system. The possible existence of the Blackstar program was reported in March 2006 by Aviation Week & Space Technology (Aviation Week) magazine; the magazine reported that the program had been underway since at least the early 1990s, and that the impetus for Blackstar was to allow the United States Government to retain orbital reconnaissance capabilities jeopardized following the 1986 Challenger disaster.
