The gas turbine industry began in the 1940s and, for many decades, it remained an object
of research by universities and government laboratories as well as the many commercial
establishments which sprang to life in an effort to exploit the technology. During this
period, much basic research was conducted and information exchange was encouraged. It
is noteworthy that the British Government, which had sponsored much of the development
of the Whittle engine, shared the entire technical package with the US Government as a
war measure. This resulted in the US Government supporting its continued development
at the General Electric facilities at Lynn, Massachusetts.
Many companies were formed in Europe and in North America during the 1950s,
each of which offered designs tailored to specific applications. In addition to the rapidly
expanding aeronautical and defense industries, other applications began to emerge for
non-aeronautical engines. These included gas pipelines, electrical power generation and
naval propulsion. In short, the industry was booming and employment for engineers was
readily obtained. More importantly, there were many opportunities to learn about this
fascinating machine.
Today, the industry is reduced to a handful of very large companies. The investment
required to develop an engine is enormous and the competition can only be described
as fierce. Engineers are much more specialized and commercial secrecy is a fundamental
element of corporate survival. For the true engineering specialist, the work remains a
fascinating push into the unknown. For the systems engineer who must develop strategies
and equipment which supports and manages the operation of the engine, the work has
however become more complex and information has become more difficult to obtain in
a form that allows synthesis of system behavior.
There are many books available that describe gas turbine engines, focusing primarily
on the ‘turn and burn’ machinery from an aerothermodynamic perspective. Typically, the
coverage given to the peripheral systems that support the complete gas turbine propulsion
system is either not described at all or is often superficial. As the industry continues to
demand improvements in performance and reductions in weight, the engine continues to be
refined and, in some instances, made more complex. The system engineer can therefore
expect to be working on not only more refined control systems but also information
management systems designed to keep ownership costs as low as possible.
This book is organized to provide the reader with a basic understanding of how a gas
turbine works, with emphasis on those aspects of its operation which most affect the
task of the system designer. We have attempted to cover the propulsion package as a
combination of functional components that must operate properly in unison to produce
power. The famous remark by Sir Frank Whittle–that the gas turbine has only one moving
part–happily neglects the many subsystems that must operate in unison with the prime
mover to create a viable propulsion system package. In Whittle’s day, it was sufficient
for the engine to run smoothly. Today, the complete engine design must take into account
cost of ownership, maintainability, safety, and prognostics and health monitoring.
The book describes the basic gas turbine in terms of its major components at a level
sufficient to understand its operation and to appreciate the hard limits of its operating
envelope. In particular, the issues associated with the handling of the gas generator or
‘core’ of the turbine engine in aircraft propulsion applications in preventing the onset
of compressor surge or flame-out during transient throttle changes is addressed in some
depth, including the need for stable speed governing in steady-state operation.
The importance of understanding and managing the engine inlet and exhaust systems
together with the issues associated with power extraction and bearing lubrication are also
given extensive coverage.
The gas turbine has found application in a number of important non-aeronautical industries.
These include pipeline compressor drives, electrical power generation and naval
propulsion systems. From a systems design perspective, the naval application is arguably
the most demanding. In keeping with the propulsion focus of this book, the naval application
has been chosen as an example of the challenges of introducing the gas turbine
engine–developed for airborne applications–into such a hostile environment. The subsystems
required to support and protect the engine in a navy ship are described in some
detail.
Finally, prognostics and health monitoring must be recognized as a key aspect of
the need to develop reliable algorithms that can effectively forecast the operational life
remaining. This is increasingly important as both the commercial and military operators
move into the realm of condition-based maintenance as a means of controlling and minimizing
cost of ownership. Some of these systems will be fitted to future engines; as their
underlying advantages are recognized, it is of equal importance that they interact with
ground-based logistics systems.
Notwithstanding the book’s focus on the system aspects of gas turbine propulsion
systems, the fundamentals of gas turbine engine design are covered to a level that is considered
more than adequate for the practicing systems engineer and/or business program
manager. In addition to the devotion of one complete chapter to gas turbine basics, there
are several appendices that provide a substantial grounding in the fundamentals of gas
turbine design, modeling and operation.
