临近空间飞艇新型推进方式

New Propulsion Method Study of Stratosphere Airship

研究了临近空间飞艇采用尾部摆动推进的特性.首先通过任意拉格朗日欧拉算法的雷诺平均N-S黏性流场计算方程建立了尾部摆动的数值分析方法,然后对各摆动参数以及环境变化下推进效率、速度及推力进行了计算分析,并通过原理飞行验证,得出该类推进方式在浮空器上应用的可行性.尾部摆动推进方式可作为常规螺旋桨推进的补充,进一步改善和提高浮空平台整体性能.

The propulsion characteristics of oscillating tails of airship were studied.At first the analysis method was built using the arbitrary Lagrangian-Eulerian Reynolds-averaged Navier-stokes equations and FLUENT UDF.The propulsion characteristics of oscillating tails under the conditions of different oscillating parameters and environments were analyzed.The calculation,analysis and flight experiment indicate that this propulsion method can be used to stratosphere airship.This oscillating tails propulsion method can be used to stratosphere airship as a supplement of the propeller to improve and enhance the performance of the floating platform.
