In the process of designing of BTT aerial bomb supporting distributed and collaborative combat, the roll jitter problem is caused by the influence of the coordinated branch during heading maneuver. To solve the problem, arc route planning and the corresponding nonlinear guidance optimization algorithm are proposed by taking advantage of the fact that the course cannot be stepped maneuver. Lyapunov stability theory is used to analyze the stability of the algorithm. At the same time, a double elliptical route safety cross-border and the over-point judgment strategy are proposed, which is suitable for the cluster coordinated BTT aerial bomb. Finally, the effectiveness of the proposed method is verified by the semi-physical simulation test. The results show that the attitude is relatively stable during maneuvering, and the roll angle jitter amplitude is reduced by an order of magnitude.
