摘要
飞机无坡度转弯技术在目标跟踪中具有重要地位。给出了飞机带坡度转弯时的操纵方法和转弯性能计算公式。根据带坡度转弯特点,分析了无坡度转弯的特点,提出了无坡度转弯操纵方法。最后给出了无坡度转弯时主要性能指标简化计算公式。建立了飞机无坡度转弯时飞机动力学模型,给出了无坡度转弯时初步控制算法。基于某飞机气动模型,对无坡度转弯操纵方式及性能进行了仿真验证,给出了提高转弯性能的建议方法。
The technology of NBT （NBT-no bank turn） for aircraft is very significant in target tracking. The Control method of turn with bank and calculated formula for turn performance are presented. Compared with bank turn, the characteristics of NBT is analyzed, operation approach for NBT is introduced, and the simplified calculat-ed expression for mainly performance index of NBT is given finally. The model of dynamics for NBT is established, initial control algorithm for NBT is formed. The operation method and performance for NBT are validated based on aerodynamics model of aircraft, the advised method of improved turning is put forward.
