The author received a B.S. degree in mathematics from the California Institute of Technology in 1949. Since that time he has been with Aerojet-General Corp., Azusa, Calif., a subsidiary of the General Tire & Rubber Co. His work at Aerojet-General has included the practical side as well as theoretical research in solid propellant rocket development; in particular, problems of heat transfer and combustion instability. More recently, within the last three years, Mr. Lipow has been a member of the reliability control staff. In this capacity he has contributed to reliability programs planning and to resolution of many of the statistical problems of reliability. Mr. Lipow has contributed several papers on reliability topics to the scientific literature.

Basic information concerning the free jet method of supersonic development testing is presented. Parameters necessary to specify test hardware, define test facility capabilities, and optimize facilities for this type of testing are discussed. The substantial gains obtainable in a facility's testable range by separately exhausting engine gas flow and free jet air spilled around the engine are defined, as are performance levels of various free jet diffuser types. A nomograph is included which permits rapid estimation of facility requirements and/or capabilities.

W an object travels through air at altitudes below something like 200,000 ft and at Mach numbers greater than 12 to 15, the production of electrons in the shocked layer of air which surrounds the object has a significant effect on some of the properties of the shocked air. Above some altitude like 200,000 ft the influence of the electrons is felt at even lower Mach numbers, particularly in the ionosphere where the ambient electron density is no longer negligible. The influence of electrons is felt not only on aerodynamic quantities such as heat transfer, drag and flow field, but also on physical quantities such as transport properties, radiative emission and absorption, and electromagnetic signal interaction. The main thesis of the present paper is to show how, and under what conditions, the electrons produced by the passage of a high speed missile through the atmosphere significantly affect both aerodynamic and physical quantities. A plasma may be defined as a gas containing electrons in sufficient quantity to seriously affect the physical properties of the gas. Plasma physics then is simply the physics of such a gas. For example, the air in the shock layer surrounding a hypersonic missile may be in a plasma state if the missile is traveling at an extremely high velocity. We will first discuss in general terms the structure of a hypersonic axially symmetric flow field. This will be followed by a more detailed discussion of the shock front and boundary layer with emphasis on the electron distribution. We will then show an example of an analysis of the Boltzmann equation and the relationship of the electron scattering cross section and the electron velocity distribution function.
