APPENDIX 2 DESCRIPTION OF ZERO-G DEVICES AND SIMULATORS 1. Name of the device, location, and dates of construction and modification. Size of the present staff. 2. Description of the mechanical system, with photographs or diagrams. Size and weight limitations of payload. 3. Motion, acceleration, and velocity characteristics. Modes of producing or simulating subgravitational and weightless states. Duration of sub- and zero-G condition. 4. If available, theoretical basis and equations representing the physical conditions for the subject seated on the device or simulator in a specified and typical manner. If available, indications of the time delays (or input-output transfer func- tions) of the control system inputs and simulator responses should be included. 5. Description of the control system (manual, automatic, tape, film, computer, etc. ). Open loop (command signal only) or closed loop (with feedback of actual performance) control. Status of mechanization and automation. Can a subject on the device be in the control loop? 6. Instrumentation and data reduction. Recording channels and noise levels. Types of information which have been, or will be, recorded. 7. Safety features and requirements. 8. Approximate cost of the device or simulator and of their use by others, and procedures for arranging such a use. Names and positions and organizational relationships in charge of the use of the device. 142
9. Description of projects and workload during the past year. If available, the schedule of planned use for the next years. 10. Bibliography, including classified reports, of journals and available government or industrial reports of all studies with the zero-G devices and weightlessness simulators of biological application. 143

NATIONAL ACADEMY OF SCIENCES NATIONAL RESEARCH COUNCIL The National Academy of SciencesâNational Research Council is a private non- profit organization of scientists, dedicated to the furtherance of science and to its use for the general welfare. The Academy itself was established in l 863 under a Congressional charter signed by President Lincoln. Empowered to provide for all activities appropriate to academies of science, it was also required by its charter to act as an adviser to the Federal Gov- ernment in scientific matters. This provision accounts for the close ties that have always existed between the Academy and the Government, although the Academy is not a governmental agency. The National Research Council was established by the Academy in 1916, at the request of President Wilson, to enable scientists generally to associate their efforts with those of the limited membership of the Academy in service to the nation, to society, and to science ft home and abroad. Members of the National Research Council receive their appointments from the President of the Academy. They include representatives nominted by the major scientific and technical societies, representatives of the Federal Government, and a number of members-at-large. In addition, several thousand scien- tists and engineers take part in the activities of the Research Council through member- ship on its various boards and committees. Receiving funds from both public and private sources, by contributions, grant, or contract, the Academy and its Research Council thus work to stimulate research and its applications, to survey the broad possibilities of science, to promote effective utilization of the scientific and technical resources of the country, to serve the Government, and to further the general interests of science.
