  "Liquid Rocket Engines."

  This paper presents a discussion on liquid propellant rocket engines. The first part contains a discussion on liquid propellants, including a description of various propellant types such as cryogenic, storable,bipropellant, and monopropellant. This part also points out desirable physical properties and includes a section on performance outlining the methods by which performance is calculated and shows performance for various liquid rocket propellant combinations.

  "Liquid Rocket Propellant Compatibility Testing."

  Material-propellant compatibility as related to liquid rocket propulsion system design criteria is discussed and applicable test methods to derive usable design data are presented. Test methods, with emphasis on metallic materials, are discussed and the shortcomings of a number of these test methods are pointed out. These tests include static immersion tests, stress-corrosion tests, flow tests, impact tests, and tests to determine the effect of cracks and notches in metals on compatibility. A general outline for the evaluation of metallic and nonmetallic materials with respect to propellant compatibility is presented.

  "List of Academic Theses Since 1961 Related to the History of Aeronautics and Astronautics."

  This preliminary listing of academic theses of interest to historians and social scientists is made available for general information, critical comments and related suggestions. The NASA Historical Advisory Committee suggested that such a listing might provide useful perspective on contemporary scholarship. Mr. Charles Atkins, a member of our Summer Seminar on "History, Social Science and Space" and graduate student in Political Science at M.I.T., kindly undertook this task. The NASA Historical Staff is also sponsoring preparation of a bibliography of bibliographies on the history of aeronautics and astronautics, and is undertaking a list of research resources available for academic scholarship. These will be available sometime this fall. Eugene M. Emme, NASA Historian.; NNH-61.; FOREWORD: This listing represents a first attempt to compile academic theses of relevance to the history of aeronautics and astronautics. It has been estimated that almost 70,000 doctoral dissertations have been completed in American universities since 1961, so this select compilation must be regarded as preliminary. In accord with the desire of the Historical Staff of the National Aeronautics and Space Administration to assist scholarly research, it is hoped that this list may be suggestive. It will, hopefully, stimulate a response which will permit additions to this listing of interest to historians and other scholars concerned with science, technology, and public policy in the twentieth century.
