A hard-to-find report (we located this one in the Kirtland Air Force Base technical library) telling about using these effective materials to prevent oxidation and erosion of rocket engine nozzles.

The investigation used a 1000-pound thrust nitric acid / aniline (JATO-type) rocket motor, with combustion gas temperatures of 2000º to 2400ºF.  The ceramic (with a high percentage of sillimanite) was used in a thin-wall nozzle backed with plaster of paris.  The experiments found that a thin chrome plating on the internal surface of graphite nozzles was quite effective.

This book gives a detailed description of the engine, nozzles, propellants, and test equipment used.  We found the innovative ceramic rocket nozzle to be quite ingenious, offering some good ideas for the "amateur" experimenter.  This nozzle functioned well even when it cracked in use.

Use of a chrome-plated graphite nozzle is also innovative, and proved successful.  Even a thin coating prevented oxidation and erosion during the burn.

The report provides excellent tables, engineering drawings, and several (poor quality) photos of the nozzles.  It's a nice reference resource for the rocket scientist, engineer, and technician--professional or "amateur."

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 jet 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 rocket engines.

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.  18 pages, large and easy-to-read 11" x 8-1/2" size.
