This
heavy, 204-page textbook represents the last word in guidance and steering
of spacecraft vehicles during the launch phase. It covers methods
of superimposing a side force on the motor thrust, which achieves a moment
about he vehicle center of gravity. Both flexible joint and liquid
injection systems are discussed in detail.
You can
learn how to design a successful flexible joint and insulate it against
hot motor gases. You'll also get an education about liquid-injection
system design, including types of injectants, piping, valves, storage tanks
and pressurization systems. (The text also covers the effect of injectant
and erosion at the injection port, and the effect of injection on pressure
distribution within the nozzle.)
Design
problems with flexible joints have been associated with the difficulty
in establishing the envelope for the moveable nozzle; definition of the
actuator power requirements to vector the moveable nozzle; definition of
allowable properties for the elastomer and the reinforcement; adhesive
bonding of the elastomer to the reinforcements; test methods that adequately
simulate the motor operating conditions; and quality control inspection
of the molded joint. This thick book covers each of these engineering
design challenges.
Liquid
injection steering systems have design problems associated with the definition
of the maximum steering-force duty cycle; determination of the optimum
location and geometry of the injector valves; and incompatibility of the
injectant with many of the materials used for the nozzle walls, seals,
and injectant pressurization system. The monograph gives emphasis
to those areas where specific technical approaches have solved design and
development problems.
Chapters
give comprehensive attention to these key topics, and several others:
Configuration
vs motor requirements
Design parameters
controlling response of the mechanisms
Material
selection
System design
Structural
and thermal analysis
Manufacturing
Testing
(both nondestructive and destructive)
Inspection
All aspects
of performance, structural, thermal, and physical boundary requirements
are explained. The handbook also covers flexible joint nozzles and
liquid injection thrust vector control (LITVC).
This
is exactly the practical information you need to design and build
a high-technology, state-of-the-art composite solid propellant rocket motor
steering system, whether you're a professional or "amateur" experimenter.
The contents
are the result of more than 30 years of investigations by the world's largest
solid propellant chemical engineers, scientists, technicians, and propulsion
contractors. Literally millions and millions of dollars were spent
obtaining this critical data.
This
seems to be the most complete and comprehensive
book ever written about how to design,
build, inspect, and test solid engine thrust vector control systems.
Study this exceptional text and you'll learn more than you ever imagined
possible about the subject.
Plus,
there's a huge glossary of nomenclature, symbols, and definitions; several
pages of technical references ... and
MUCH
more not mentioned here!
Need
we say there's abundant (and essential!) algebraic formulae and
equations included (get out your slide rule!), working with a wide variety
of common and complex grain geometries and motor designs?
And it
has more than 60 superb illustrations, photos, figures, engineering drawings,
tables, charts, and graphs. Her are a few (smaller-than-in-the-book)
examples:
