摘要/Abstract

摘要： 为了适应发展智能无人机的趋势,在国家大力发展海军远洋战略投送能力之际,对双飞翼无人机进行研究。采用CATIA软件概念设计双飞翼无人机,并基于计算流体力学(Computational Fluid Dynamics,CFD)理论,数值模拟双飞翼无人机的气动流场特性,并对双飞翼无人机在航母上起飞的性能进行分析。研究结果表明：双飞翼无人机在迎角为0°时,升力系数为0.596 2,阻力系数为0.037 6,升阻比为15.824 2;在航母飞行甲板起飞时,其最大起飞质量能够达到24 t,而其需用推力约为34.562 kN。

Abstract: Follow the rapid progress of the nation's blue ocean strategic projection capability of sea power, an Unmanned Aerial Vehicle (UAV) with double-all-wing configuration is studied to match the trend. The UAV is conceptually designed by CATIA software, the aerodynamic characteristic of the model is numerically simulated by computational fluid dynamics (Computational Fluid Dynamics, CFD) theory, and the performance of the UAV to take off from the aircraft carrier is also analyzed. The lift coefficient, drag coefficient and lift-drag ratio of the double-all-wing UAV model with a angle of attack of 0 can reach 0.596 2, 0.037 6 and 15.824 2 respectively. The maximum take-off load of the designed UAV can reach to 24 tons and the required thrust is about 34.562 kN when taking off from the flight deck of the carrier.

Key words: conceptual design, double-all-wing configuration, computational fluid dynamics, numerical simulation, aerodynamic characteristic
