Tri-Engine Single Thrust Vector Analysis for Yaw Movement of Flying Wing

摘要

When moving away from the conventional aviation concepts the most crucial areas of concern are efficiency and accuracy. In any design advancement, the efficiency stands with the fuel consumption and accuracy stands with the operational capabilities. Considering the design concept of the flying wing, the shortages are reflected in the effect of inability of yaw movement due to unavailability of vertical fin. In most problems of engineering the solutions used to be found mostly in nature. In most design aspects of aviation flight dynamics of birds have given solutions and this area of drawback can be taken into broader understanding with the same examples. For this constraint the aerodynamic aspects of the `swift' bird were considered. With its ability to handle critical manoeuvres under high speed flight conditions and achieving such with vectored tail movements were assessed. The method of thrust vectoring was considered by movement of engine to achieve necessary movement. In this research the control capabilities which affected thrust vectoring were calculated. As the primary design was built upon the usage of three engines the vector capability of a single engine with forward thrust of the rest were taken into consideration. By taking the same conditions delivered in the research “KF implemented Flying Wing”, this research was built upon. Thus proper condition requirements to give the optimal efficiency and accurate manoeuvring were calculated and presented. The theoretical findings of this research will be forwarded for further studies in computational fluid dynamics simulations and practical testing for prototype model with the Wind Tunnel. Furthermore multi engine thrust vectoring will be comparatively smoother attitude manoeuvring methods. The suggestions made will give the technical advantage for practical approach for engine movement requirement. In this research the readily available drawback of Flying Wing concepts are addressed.
