Today many reasons are available for comprehensive change of energy
generation and consumption methods. Global warming, high price of fossil
fuels and geopolitical problems
linked to them in addition to limitations of their mining are the most
important factors to boost researches into finding new ways to consume
and generate energy.
Most of the ways currently available to adapt conventional power systems
to today’s demands dedicate power to requirements. To reduce emission,
noise and other factors, recently known as crucial, power suffers
maximum cost.
However, can we find a way to save power when emission is considerably
being reduced?
This question encouraged the author to explore such a way. Accordingly,
he considered the most essential parameter
influencing a power system emission, is the adaptive ability to
environmental elements and user demands or Context-Awareness.
In this way, reducing energy consumption of available devices is one of
the most effective methods. This work needs few changes in
infrastructures and it can satisfy requirements in mid and long terms
with minimum const. However, such a development should not increase
complexity of systems, in fact more complicated systems potentially can
raise cost and reduce tendency to use them.
Author believes introducing new definitions, mostly used in IT world,
into power and propulsion systems is capable to turn these devices into
desirable way compatible with today and future demands.
One of the most prominent factors to heighten performance and fuel
efficiency of power and propulsion systems is their capability to adapt
to operating conditions. In fact, many of the optimizations have been
carried out toward improving this capability. However, author believes a
new view is necessary to create real adaptive capability in them.
Since early in the 2000, author has focused his researches on creating
new generation of gas turbines with superior ability to adapt to user
demands and environment requirements. This category of engines has
played an important role in power generation and propulsion, and then
adaptive capability is crucial to heighten its performance. As a result
author tried to introduce “Context-Awareness” into gas turbine engines.
Context-Awareness, a definition created in IT and computer world, urges
such a dynamic structure that system would be able to understand user
demands and environmental elements as input and adapts itself to them as
output.
In first phase changing available configuration toward context-aware
system was considered. To cast proper dynamic adaptation capability into
gas turbine engine construction, creating an open access to components
individually is essential. However, existing consistency among them is
crucial to generate power and thrust. In a word, coherent consistency
should replace strong link among engine’s components.
Individual operation of turbine on the framework of free power unit and
combustor, which reflects user demands, are able to adapt to
Context-Awareness, however, approaching gas turbine engine to desirable
characters requires making essential changes in power transmission and
compressor operation.
In order to pursue this idea, author introduced a new generation of
axial flow compressors (see article 3, 4) and a novel hybrid cycle which
is suitable to be operated in vehicles (see article 2).
However, imposing suitable specification on conventional compressor
increases complexity besides difficulties to adapt configuration to
desirable character. On the other hand conventional form has not enough
capacity to rise up to such an advanced system.
As such author attempted to design the new generation of compressors
which are inherently capable to support Context-Awareness. Accordingly,
this principle was considered that the compressor should be capable to
operate by several simple components, which are able to work
independently and coherently under integrated management. Moreover,
author has believed that an advanced device operates based on its
molecular properties rather parts. Such a device consumes energy and
works by components forming its molecular structure. A good sample of
such a device is a computer processor, which performs heavy duties by
millions of components when all of them form a part. Such a view led
author to design a novel compressor by Dielectric Elastomer Actuators
(DEA). In fact, its effect on the gas turbines can be similar to
transistor effect on the electronic devices early in the 1970s. This
device mimics behavior of a type of muscles to produce gullet like
rather linear movement. For more details, (see article 1). |
