IMPROVEMENT
OF SMALL GAS TURBINE ENGINES OF UNMANNED AERIAL VEHICLES ON THE BASIS OF QFD
METHODOLOGY THE FIRST LEVEL
Currently,
promising line of aviation development is perfection
unmanned aerial vehicles (UAVs) [1].
First
of all, great attention devoted the power plants of the UAVs [2]. Modern aircraft
engine is a complex and expensive machine that is created using the latest
science and technology. In turn, perfection
aircraft engines advances new requirements on the technology of their
production.
The
modern aviation uses of different types of gas turbine engines. This is due to
the diversity of aircraft types and specific requirements for their power
plant.
The
modern trend toward miniaturization, portability has led to the development of
small gas turbine engines (SGTE). These small engines become a new trend in
small aircraft [3].
The
purpose of my effort - perfection the
design of SGTE UAV based on the methodology of deploying the quality function
(QFD).
The
QFD methodology used for a better understanding of the expectations of
consumers. While designing, developing and improving products, services
increasingly emanating on stated and implied needs of consumers.
In
world practice, the methodology of QFD is one of the most effective methods in
quality’s assurance. In Russia, this method is beginning only to develop and implement in practice.
The
purpose of QFD is ensuring quality of products produced at each stage of the
life cycle, which would guarantee a final result that meets the requirements
and expectations of the consumer [4].
The
phase one in the deployment of quality function (QFD) [5] is the identification
of all the requirements of consumers. In our case, the technical consumers SGTE
will be unmanned aerial vehicles (UAVs). As the object-analogue selected small
turbojet engine TJ100 [6], which is a subspecies of small gas turbine engines.
The second stage was to conduct benchmarking of the technical characteristics
of SGTE UAV. This TJ100 compared with the MD 45 and MD-120.
The
basis of QFD is the construction matrix, according to its form “the House of
quality”, in which recorded information about the quality of the product and
decisions.
After
analyzing “the House of quality” SGTE UAV, after correlation requirements, the
priorities ranked. This is done in order to identification and preparation of
three main areas, three important technical characteristics which you need to
start improving SGTE UAV.
“The
House of quality” in this effort was formed with the help of specialized
applications of QFD-online.
By
results of the conducted QFD SGTE UAV first level we can draw the following
conclusions. First, it is necessary to reduce the dry weight of the engine.
Secondly, to increase the rate of adaptability. The third is to change the
material to make it more quality, but cheap.
