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.
