凹角

The secondary mass flux, Z, cavity convergence/divergent angle, and injection angle have different effect on internal performance of DTN.

二次流量、落压比、凹腔扩张角和收敛角、引射角度都对推力矢量状态下的DTN内流性能有着不同的影响。

In order to achieve a tradeoff between vectoring and unvectoring state, the proposed parameters of DTN are: Z=3~4, secondary injection flux is about 3%, cavity divergence angle is about 10°, cavity convergence angle is 20°~30°, injection angle of secondary is about 30° by counterflow injection.

为了实现DTN在推力矢量和非推力矢量下都有较好的内流综合性能，所建议的设计参数为：落压比为3~4，引射量为3%，凹腔扩张角为10°左右，收敛角在20°~30°，引射角度为30°逆流引射角(β=30°)。
