1) condensation trail
凝结尾迹
1.
This paper analyzes the thermodynamics principle of forming jet aircraft s condensation trail and suggests that adding some kinds of additive to fuel should prevent the occurance of condensation trail.
分析了喷气飞行器产生凝结尾迹的热力学原理,建议在航空燃油中掺入某种添加剂,以抑制凝结尾迹的发生。
2) aerodynamic trail
气动力凝结尾迹
3) condensation trail; contrail
凝线尾迹
4) wake structure
尾迹结构
1.
The wake structures over the flame holder were analyzed, and the following were confirmed: The slitted bluff body with proper gap ratio (δ/d=18%) may have the features of low drag and stable flame-holding.
对尾迹结构的分析结果表明 :如果选择合适的缝宽比 (δ/D =18% ) ,开缝钝体可同时具有阻力低、火焰稳定性好的特点 ;而在缝宽比δ/D =10 %和δ/D =2 5 %两种情况下 ,由于主、次回流区和中缝流之间的干扰加剧 ,易形成尾迹振荡 ,增加总压损失 。
6) jet-wake flows
射流-尾迹结构
补充资料:飞机尾迹
[[飞机尾迹]]:飞机飞行中发动机排出的废气与周围空气混合凝结而成的特殊的云。一般发生在气温低于-40度、又有适当湿度条件的空气层中。飞机尾迹对飞行没有影响,但暴露行踪,对航空兵战斗行动有一定的影响。
