General Design and Aerodynamic Analysis for an Original Flying-Wing and Moving-V-Tail UCAV

The general layout design of aircraft has been significantly developed in the aviation history of the past five score years. However, it is apparent to witness the bottleneck and hard to break through traditional creation in the last decade. In this paper, aiming at future’s war mode of systematic battle and considering the engineering application potential of cutting-edge technology, the general design of an original flying-wing and V-tail UCAV, which is mainly used for electromagnetic attack is described and modeled; Based on computational flight mechanics and principle of stealth, the performance parameters are provided and structure design is carried out; According to the division criteria of the fighter general arrangement, bay definition of the whole UCAV is launch. Besides, applying CFD means, the main aerodynamic characteristics especially the efficiency of two degree of freedom moving V-tail layout are analyzed. The results show the excellent cruise performance and acceptable maneuver characteristics of this platform which could be realized for a variety of task demands such as distributed detection, systematic countermeasures and focused killing. Moreover, this paper could be an effective reference for innovative aircraft design and exploration.
