Wartime Reports:  Tests of a 22-Inch Diameter Pulse-Jet Engine

National Advisory Committee for Aeronautics (NACA)
Aircraft Engine Research Laboratory, Cleveland, Ohio
Predecessor to NASA

This is a rare collection (of 4 highly-important research reports) of special value to pulsejet engineers, designers, and experimental engine developers, both "amateur" and professional. 

We've found these early U.S. research project reports quite valuable for "hands-on" experimental work.  They employ the materials, technology, and tools commonly available everywhere (as opposed to the hard-to-find, expensive exotics used in more recent projects).  Thus, these reports are exceptional reference resources for developers of pulsejet engines, as well as ram jets, gas turbines, and turbojets.

Each section contains many engineering drawings, graphs, tables, and charts of design and performance data that can't be found elsewhere.  The drawings and photos are extremely useful for "build-it-yourself" enthusiasts, and include early U.S. experimental pulse jet engines similar to those of the original German V-1 Schmidt-Argus cruise missile powerplants.

These documents were long classified ("Confidential") military secrets!  Now we're making them available again.  The book contains these essential reports:


  • NACA WARTIME MEMORANDUM REPORT E5J02: Sea-Level Performance Tests of a 22-Inch-Diameter Pulse-Jet Engine at Various Simulated Ram Pressures
  • NACA WARTIME MEMORANDUM REPORT E6E15:  Effect of a Low-Loss Air Valve on Performance of a 22-Inch-Diameter Pulse-Jet Engine
  • NACA WARTIME MEMORANDUM REPORT E6G01:  The Effect of Increase in Combustion-Air Inlet Temperature From 80° to 130°F on the Sea-Level Performance of a 22-Inch-Diameter Pulse-Jet Engine

  • NACA TECHNICAL NOTE NO. 1702:  Analytical and Experimental Performance of an Explosion-Cycle Combustion Chamber for a Jet-Propulsion Engine


The book includes many vital graphs of pulsejet performance data, essential for engineering and design work.  Here's a small sampling of the many graphs and tables included in this thick, comprehensive text (although these images are far less sharp and clear than in the actual book):


Even more of interest are the many excellent engineering drawings and photos of pulsejet engine components and test equipment in this volume.  Here's a sampling, shown at MUCH less resolution and smaller size than in the actual book:

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 pulse jet 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 pulsejet 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 collection of the most important results of NACA research on pulsejets.  The projects described were preceded by the first glide flight of the AAF-NACA XS-1 rocket research airplane in January 1946, and the breaking of the sound barrier, on November 14, 1947. 

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.

If you fly a Dyna-Jet or any similar pulsejet-powered model airplane, this book will provide a lot of technical information to supplement your knowledge.  (The NACA pulsejet engine tests are simply large-scale experiments with engines very similar in design and function to that of the DynaJet, MEW, Tiger-Jet, SilverJet, MiniJet, and other smaller "explosion pulse-cycle" engines.)  It will also give you many hints on getting the highest performance from your aeromodel powerplant.
