Liquid Rocket Valve Components

by Rocketdyne, TRW, Aerojet-General and NASA Lewis Research Center scientists and engineers

This is a thick, heavy, and highly-detailed technical reference for the advanced liquid propulsion engineer.  It contains the results of more than 40 years of research and development by the world's leading liquid rocket companies.  Millions and millions of dollars went into the rocket, missile, and space projects that produced this wealth of critical information and data.  Indeed it's a text by the experts, written for the serious professional or "amateur" (non-professional) rocket scientist or engineer.

The 140-plus pages includes explanations for design and use of every imaginable liquid propellant valve component.  You'll find complete, comprehensive, state-of-the-art information and data for:

  • Poppet valving units:
    • Hard-on-hard and hard-on-soft units
    • Geometric and surface finish
    • Static seat stress
    • Transient seat stress
    • Soft seal retention
    • Static seal stress
    • Alignment
  • Butterfly disk valving units:
    • Geometry and surface finish
    • Seal retention
    • Retainer configuration and loads
    • Thermal contraction of retainer bolts
    • Interference of disk and seal
    • Alignment of disk and seal
  • Ball valving units:
    • Geometry and surface finish
    • Seal retention
    • Seal stress
    • Alignment
  • Blade valving units:
    • Geometry and surface finish
    • Seal retention
    • Seal stress
    • Alignment
  • Rotary and linear sleeve units
  • Cylindrical slide valving units: spool and cylindrical units with internal seals
  • General considerations in valving unit design
    • Vibration
    • Contamination
      • Contamination tolerance
      • Contamination control
  • Housings
  • Shafts
  • Bearings
    • Guide bearings
    • Journal bearings
    • Rolling-contact bearings
    • Thrust bearings
  • Secondary seals
    • O-rings
    • Lip seals
    • Interference of disks and seals
    • Alignment of disks and seals
    • Face seals
    • Bellows
    • Pressure-balancing-piston seals (sleeve seals)
  • Materials for valve units and elements
  • And much, much, much more not mentioned here!

There are also dozens of detailed engineering drawings, figures, illustrations, and tables to support the text--and a thick appendix.  Here is a small sampling of the graphics (shown at much lower resolution, and smaller size, than in the real book):

Almost all of this data and information was classified as secret until the time of this report.  The text goes into great detail about valve dimensions, flow rates, operating pressures, actuation, response times, etc. for assemblies used in almost all important liquid propellant missile systems, including:

  • Atlas MA-5 engines
  • Thor MB-3 engine
  • Titan III (LR-87-AJ-5 and LR-91-AJ-5 engines)
  • Saturn S-1B H-1 engines
  • Saturn S-1C F-1 engines
  • Saturn S-II J-2 engines
  • Saturn S-IVB J-2 engines
  • Saturn S-IVB system
  • SE-7-1 APS (ullage engine)
  • Centaur RL-10 engines
  • Centaur 8093 (attitude control)
  • Intelsat III thruster
  • Gemini (RCS and OAMS)
  • Apollo Command Module engines
  • Apollo Service Module engine
  • Apollo R-4D (RCS)
  • Lunar Excursion Module descent and ascent engines, and RCS
This fine handbook will provide solid information for everyone who designs, builds, tests, or uses serious liquid propellant rockets.  It's the official NASA valve component design guide, full of scientific data, rocketry information, and military missile lore, providing data on all types of liquid rocket valves.  And it's the ideal text for "amateur" experimental rocket scientists.  Even though it's oriented toward "grand" rockets and spacecraft systems--like Saturn, and the Apollo Lunar lander--the information applies as well to "backyard" homebuilt liquid and monopropellant rockets!  Heads up, all you serious "amateur" rocket scientists and engineers!

It's perhaps the most complete and comprehensive book ever written about the theoretical and practical engineering design of liquid rocket valve components.  Thick, heavy, and packed with accurate information, it's an exceptional reference resource for the professional (and serious “amateur”) rocket scientist, engineer, technician, and experimenter.

Plus you'll find 11 pages of technical references (149 different studies are listed), a 10-page glossary of arcane symbols and definitions used in valve design ... and MUCH more not mentioned here!

If you design, build, test, or fly serious liquid rockets or missiles of any size, you'll want this superb reference textbook.  It’s especially useful for “amateur” rocket builders--there's nothing else quite like it anywhere!

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.  159 pages, large and easy-to-read 11" x 8-1/2" size.  $24.95
