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). -

Genetic Algorithm Optimization of a Cost Competitive Hybrid Rocket Booster George Story1 NASA MSFC Huntsville, Al Performance, reliability and cost have always been drivers in the rocket business. Hybrid rockets have been late entries into the launch business due to substantial early development work on liquid rockets and solid rockets. Slowly the technology readiness level of hybrids has been increasing due to various large scale testing and flight tests of hybrid rockets. One remaining issue is the cost of hybrids vs the existing launch propulsion systems. This paper will review the known state-of-the-art hybrid development work to date and incorporate it into a genetic algorithm to optimize the configuration based on various parameters. A cost module will be incorporated to the code based on the weights of the components. The design will be optimized on meeting the performance requirements at the lowest cost. I. Introduction Hybrids, considered part solid and part liquid propulsion system, have been caught in the middle of development goals of the various NASA and military programs. Solid rocket motor technology has matured due to the design simplicity, on-demand operational characteristics and low cost. The reliability of solids, given minimal maintenance requirements, made them the ideal system for military applications. On the other hand, liquid rocket engine technology has matured due to their higher specific impulse (ISP) over solids and variable control thrust capability. Hybrid Rockets have been used in only one flight-production application (Teledyne Ryan AQM-81A ‘Firebolt Supersonic Aerial Target) and one series of recent manned flight demonstrations (Burt Rutan’s SpaceshipOne), suggesting that advantages have been overlooked in some potential applications. -

Beginning with the Program and Project Management Initiative (PPMI) in 1988, which was founded in response to the Challenger disaster, NASA leadership identified a need to develop program and project management excellence in the workforce through training. Ten years later, the agency outgrew the PPMI model as its mission portfolio and workforce evolved. The renamed APPEL grew to place a greater emphasis on curriculum, certification, team performance, and knowledge sharing across NASA. Since then, the Academy’s initiatives have provided support to the agency’s technical workforce through its integrated curriculum, team support services, and knowledge sharing activities. In January 2012, a Congressionally established advisory group called the Aerospace Safety Advisory Panel, recommended that NASA establish a single focal point within the agency to develop the policy and requirements necessary to integrate knowledge capture across programs, projects, and centers. In response, NASA appointed its first-ever agency-wide Chief Knowledge Officer (CKO), building upon of the wealth of knowledge sharing activities already underway across NASA, including APPEL. -

The Challenger Disaster

Rossow, P.E., Ph.D. © 2015 Mark P. Rossow All rights reserved. No part of this work may be reproduced in any manner without the written permission of the author. 2 Preface On January 28, 1986, the Space Shuttle Challenger was destroyed in a disastrous fire shortly after liftoff. All passengers aboard the vehicle were killed. A presidential commission was formed to investigate the cause of the accident and found that the O-ring seals had failed, and, furthermore, that the seals had been recognized as a potential hazard for several years prior to the disaster. The commission’s report, Report to the President by the Presidential Commission on the Space Shuttle Challenger Accident, stated that because managers and engineers had known in advance of the O-ring danger, the accident was principally caused by a lack of communication between engineers and management and by poor management practices. This became the standard interpretation of the cause of the Challenger disaster and routinely appears in popular articles and books about engineering, management, and ethical issues. But the interpretation ignores much of the history of how NASA and the contractor’s engineers had actually recognized and dealt with the O-ring problems in advance of the disaster. When this history is considered in more detail, the conclusions of the Report to the President become far less convincing. -

Round Trip to Orbit: Human Spaceflight Alternatives
Round Trip to Orbit: Human Spaceflight Alternatives August 1989 NTIS order #PB89-224661 Recommended Citation: U.S. Congress, Office of Technology Assessment, Round Trip to Orbit: Human Spaceflight Alternatives Special Report, OTA-ISC-419 (Washington, DC: U.S. Government Printing Office, August 1989). Library of Congress Catalog Card Number 89-600744 For sale by the Superintendent of Documents U.S. Government Printing Office, Washington, DC 20402-9325 (order form can be found in the back of this special report) Foreword In the 20 years since the first Apollo moon landing, the Nation has moved well beyond the Saturn 5 expendable launch vehicle that put men on the moon. First launched in 1981, the Space Shuttle, the world’s first partially reusable launch system, has made possible an array of space achievements, including the recovery and repair of ailing satellites, and shirtsleeve research in Spacelab. However, the tragic loss of the orbiter Challenger and its crew three and a half years ago reminded us that space travel also carries with it a high element of risk-both to spacecraft and to people. Continued human exploration and exploitation of space will depend on a fleet of versatile and reliable launch vehicles. As this special report points out, the United States can look forward to continued improvements in safety, reliability, and performance of the Shuttle system. Yet, early in the next century, the Nation will need a replacement for the Shuttle. To prepare for that eventuality, NASA and the Air Force have begun to explore the potential for advanced launch systems, such as the Advanced Manned Launch System and the National Aerospace Plane, which could revolutionize human access to space. -
