Experimental Investigation of a Lightweight Rocket Chamber

National Advisory Committee for Aeronautics (NACA)
Predecessor to NASA
This is a rare and unusual technical report discussing fabrication and testing of lightweight rocket motor combustion chambers formed from sheet metal. These designs are both inexpensive to build and of simple design. They are inexpensive, require very little machining, no an elaborate machine shop to produce. In fact, the procedure described produces very little scrap metal!
Using a jacketed design, this NACA team developed successful rocket engines that produced from 1000 to 5000-pounds of thrust, with operating chamber pressures of 300 to 600-pounds per square inch. The innovative motors were built of sheet-metal skins, and formed to give simple, helically-wound coolant passages.
Some of these engines were also wrapped with layers of fiberglass cloth, bonded with a polyester resin glue. One motor, yielding 1000-pounds of thrust, weighted only 3.5 pounds, giving a ratio of thrust to weight of 285!
The engines were tested with liquid oxygen and ammonia, liquid oxygen with various hydrocarbons, and high-impulse propellant combinations. Regenerative as well as water cooling was tested, and run durations ranged up to 60 seconds. The report provides static test run data with various types of fuel injectors.
This book is of special value to rocket scientists, engineers, designers, and experimental engine developers, both "amateur" and professional. Long-lost and very hard to find, our copy was located in an obscure technical library at a remote Air Force Base in New Mexico.

From 1915 until 1958, the National Advisory Committee for Aeronautics (NACA) carried out much of the cutting-edge research in aeronautics in the United States.
Originally created in an effort to organize American aeronautical research and raise it to the level of European aviation, from the beginning, NACA emphasized research and development. By 1920, the NACA had emerged as a small, loosely organized group of leading-edge scientists and engineers.
In 1940, Congress authorized the construction of an aircraft engine research laboratory near Cleveland, Ohio. Dedicated in 1943, it became Lewis Research Center in 1948, named after George Lewis, former NACA director of aeronautical research. These advanced projects were carried out at the then-new Lewis Laboratories.
NACA was a valuable disseminator of information to designers and manufacturers. Research results distributed by the committee influenced American aviation technology, and its reports served as the basis for many innovations that were built into American civil and military aircraft.
High-speed flight research after World War II was often a collaboration between the NACA and the U.S. Army Air Force. In 1945, the U.S. Army Air Forces NACA began the first of a series of experimental aircraft projects, many of which were designed to develop technology for high-speed flight.
At Lewis, NACA translated German documents on rocket propulsion tests that became basic references in this new field of research. Italian and German professionals came to Lewis to work with their American colleagues in these new aspects of flight research. This book is a report on some of the most important results of NACA research on innovative rocket engine designs.
The NACA ceased to exist on October 1, 1958, succeeded by the National Aeronautics and Space Administration (NASA), which was formed largely in response to Soviet space achievements. NACA became the nucleus of the new agency, and all NACA activities and facilities were folded into NASA.
Very hard to find and now out-of-print, this new limited edition has been republished by the Rocket Science Institute. It's printed with a high-resolution laser printer (not photocopied) on high-quality, bright-white, acid-free paper and quality bound for years of reference use. 12 pages, large and easy-to-read 11" x 8-1/2" size.
