A comprehensive
document covering the experience and knowledge accumulated in rocket development
and operational missiles and space programs. Covers design practices
that give increased reliability and greater efficiency.
Centrifugal
pumps have long been used successfully in chemical as well as nuclear rocket
engines. They have simplicity, reliability, light weight, wide operating
ranges, minimal development time, and relatively low cost. Usually,
other types of pumps become competitive with the centrifugal design only
when multistaging is necessary or maximum efficiency of operation is the
paramount consideration.
Written
by rocket scientists and engineers to teach other scientists and engineers,
this is one of the best textbooks available on this subject. The
material also has applications for automotive racing engineers, aircraft
mechanics, racing boat developers, and others who employ turbopump technologies.
The document
examines the various common pump problems: impeller rubbing that results
in oxidizer-pump explosions; bearing failures caused by high axial and
radial thrust; excessive cavitation damage; inadequate suction performance;
undesirable oscillations in suction and discharge pressure; impeller blade
failures; housing ruptures; stress-corrosion cracking; loss of design fits
caused by centrifugal or thermal loads; static-seal leakage; and inadequate
retention of the components.
Much
of the content was classified "SECRET" until the time of this book.
It includes information derived from the Titan, Atlas, Thor, Saturn, Redstone,
Nerva, and other related projects. Includes considerable in-depth
mathematical formulae and equations explaining the design process.
