摘　　要：对连接翼气动布局实现直接力控制的可能性进行了初步的探索。通过前、后机翼的升降舵面的不同偏转角组合，分别产生直接升力、侧力和阻力，提高了飞机的气动性能，并改善了控制的响应品质，给飞机提供了独立的姿态或轨迹控制的非同寻常的运动模态。增加头部鸭翼可进一步提高和改善了连接翼布局的直接升力特性。机翼的升降舵面的反对称偏转产生的直接侧力特性优于正常布局，无需配平并对航向稳定性影响不大。This paper presents an approach to possibility of direct force control on the joined wing configuration. The direct lift, side force and drag are respectively produced by different conbined deflection of control faces on the front and rear wings, increasing the aerodynamic performance of airplane, improving the response characteristics of control and providing unique modes of aircraft motion about independent attitude or path controls. The added front canard increases the direct lift characteristics of the joined wing configuration further. The direct side force characteristics provided by asymmetry deflection of the control faces is better than that of the traditional configuration without matching and less influence to directional stability.
