Howard Seifert, Mark M. Mills and Martin Summerfield, 3 articles in American Journal of Physics, 1947. Including: (1) "The Physics of Rockets"; (2) "Physics of Rockets: Liquid Propellant Rockets"; and (3) "Physics of Rockets, Dynamics of Long Range Rockets" in the full sammelband of the three parts paginated pp 1-284. Articles as follows: (1) "The Physics of Rockets" pp 1-21vol 15/1, January-February 1947. (2) "Physics of Rockets: Liquid Propellant Rockets" pp 121-149, vol 15 no. 2, March-April, in the issue of pp 95-198. (3) "Physics of Rockets: Liquid Propellant Rockets , the May-June issue, vol 15 no. 3, pp 255-274. The three issues are bound together. New binding, blue leatherette-bacjed maroon leatherette boards with a paper label on the cover. The binding is new; the text is GOOD. There are some bumped upper corners of the text from pg 199 to the end where the issue mmust've been roughtly handled. Also there is a corner (upper left) of the first page that has been replaced. This is evidently the first comprehensive study of the physics of rocketry published in the United States after World War II (according to Jeremy Norman, who has a beautiful full signed presentation copy of the offprints of these three papers) and a home-brewed composition of collaboration of three members of the Caltech JPL. "Although the Chinese are credited with the use of gunpowder rockets as early as several centuries B.C., and Hero of Alexandria invented a steam jet propulsion device about 100 B.C., most of the serious effort to develop rockets has occurred in the last three decades. Goddard in America made a complete study of rocket performance in 1914. The German all-out rocket program commenced in 1935 culminating in the V-2, which was first fired in September of 1944. Since 1938, intensive rocket research has been carried out by a number of American agencies, including a basic theoretical contribution by Malina in 1940. The present paper will concern itself only with that type of jet propulsion device designated as a "pure" rocket, i.e., a thrust producer which does not make use of the surrounding atmosphere. This restriction excludes propulsive duct devices such as the "turbojet" engine used in jet propelled airplanes of the P-80 type. No attempt will be made to discuss the aerodynamics of bodies moving at supersonic speeds, the electronic problems of rocket missile guidance and control, the measurement of physical quantities in the upper atmosphere, or the properties of weapon rockets. Even omitting these interesting fields, the science of rocketry embraces many phases of physics and chemistry, as will appear in later sections."--from the opening of the first paper. …
