本文介绍对一种采用涡控制技术的新概念兵器─—环翼以及升力体航天飞机的低速气动力数值模拟。对这类外形复杂、流动状态也十分复杂的流场，需正确模拟出流场不同部分的流态及湍流运动参数。本文采用一种主要与流场平均运动涡量相联系的新的湍流模型，较好地解决了这一问题。数值计算给出了大量满足工程要求的气动参数，并解决了一些关键性气动问题。 This paper presents a low-speed aerodynamic numerical simulation of a new concept of weapons using a vortex control technique, the ring-wing and the astronaut lift. For such a complex flow field is also very complicated flow field, the flow field must be correctly simulated flow and turbulent motion parameters. In this paper, a new turbulence model, which is mainly associated with the mean vorticity of flow field, is adopted to solve this problem. Numerical calculations give a large number of aerodynamic parameters that meet the engineering requirements and address some of the key aerodynamic issues.
