Liquid Propellant Gas Generators

by Aerojet, Bell Aerospace, Rocketdyne, and NASA scientists and engineers

A very complete and comprehensive technical book that collects decades of experience and knowledge accumulated in military and aerospace development and operational programs.  The text reviews design practices that give reliable and efficient gas generators for a variety of uses.

It's a systematic presentation of the large and previously loosely-organized body of existing successful design techniques and practices.  Its value and merit are obvious--these machines work!

Contents include details about virtually every kind of modern monopropellant and bipropellant gas generator system.  It reviews, in great detail--supported by exceptional engineering drawings--these many topics, and more:

  • Chamber shapes and sizes
  • Exhaust outlets
  • Mixing baffles and turbulence rings
  • Mounts and thermal protection
  • Materials and fabrication
  • Injector types and elements
  • Injector and film-cooling orifices
  • Poppet valves
  • Manifolds and interpropellant seals
  • Injector materials
  • Igniters
  • Flanges and fasteners
  • Auxiliary injectors and drains
  • Heat control
  • Trays and retainers
  • Catalyst materials
  • Catalyst beds and packs
  • "Poisons"
  • Wall dams
  • Common problems
  • Pressure measurement and tap locations
  • Temperature measurement; thermocouple durability and insulation
  • Testing (both mono- and bipropellant systems)
  • Contamination and safety

Numerous fine, NASA-quality engineering drawings, figures, and tables supplement the technical material, including:

  • Axial-outlet axial- and reverse-flow systems with various turbulence rings
  • Side-outlet generator systems
  • Uniform mixture ratio (UMR) injectors
  • Face-shutoff poppet valve injectors
  • Insulator and airgap heat blocks
  • Enzian-plate auxiliary injectors
  • Hydrazine gas generators
  • Hydrogen peroxide (H2O2) gas generators
  • Holders for igniter crystals

Detailed specifications--all once highly secret!--are given for gas generators used in many military and aerospace systems, including:

  • F-1, M-1, J-2, H-1, and E-1 engines
  • Atlas sustainers
  • Atlas MA-3 boosters
  • Thor
  • Agena
  • Titan II 1st and 2nd stage
  • Jupiter
  • Jupiter storable
  • Redstone
  • Navaho
  • Vanguard 1st stage
Prepared at the NASA Lewis Research Center by scientists and engineers from Aerojet-General Corporation, Rocketdyne Liquid Rocket Division (North American Rockwell Corporation), and Bell Aerospace--the leading commercial makers of gas generators for military and aerospace applications--this valuable book gives the practical information you need to design and build a high-technology, state-of-the-art liquid propellant gas generator (or a monopropellant or hybrid rocket engine). 

The contents are the result of more than 25 years of investigations by the world's largest propulsion contractors.  Literally millions of dollars were spent obtaining this critical yet hard-to-find data.

In a word, this is the most complete and comprehensive book ever written about the theoretical and practical engineering design of liquid propellant gas generators.  It also covers exactly how one goes about designing, building, and testing a system that works reliably.

The detailed information about using concentrated hydrogen peroxide and catalysts is alone worth the price of the book!  It’s thick, heavy, and packed with accurate information for the professional (and “amateur”) rocket scientist, engineer, technician, and experimenter.

Plus an 3-page glossary of nomenclature, symbols, and definitions; 25 technical references  ... and MUCH more not mentioned here!

If you design, build, test, or fly serious rockets or missiles, you'll want this superb reference textbook.  It’s especially useful for “amateur” rocket builders -- with an abundance of data, esoteric information, and once-secret lore from the world's foremost rocket builders: Aerojet, Rocketdyne, Bell Aerospace and 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 for years of reference use.  103 pages, large and easy-to-read 11" x 8-1/2" size.
