two-ribbon flare

The results show that ( 1) The 3B/ X3 flare on Feb.4, 1986 was possibly caused by the current loop coalescence instability between two filament current loop s: ( 2) The resistive tearing instability is an efficient Pre-heating mechanism of pre-flare phase;

结果表明：（1）1986年2月4日的3B／X3耀斑可能是由暗条电流环之间的合并不稳定性所致；（2）电阻撕裂模不稳定性是一种有效的耀斑前预热机制；

a flare-up of tension between the two sides

双方剑拔弩张

Different control laws are designed to fit the two phases of flare control and glide slope control separately. ( 2) The design of control laws of altitude adjusting, head adjusting, glide slope and flare control.

设计了高度调整、航向调整、下滑、指数拉平等各阶段和航向保持、高度保持控制规律。

In this paper, the equivalent airfoil flexible model for the aerodynamic calculation and the two body hinged model for the flare control force calculation of a parafoil is established.

本文建立了可控翼伞气动力计算的等效翼型&柔性模型以及雀降操纵力计算的双体铰接模型。

The bottom slamming forces and bow flare slamming forces are computed by matching the two-dimensional section and the three-dimensional hydrodynamic computation mesh.
