升力体布局常见于航天器的设计中,在低速领域较少应用;但其紧凑的布局,巨大的升力体面积,充足的载物空间,翼身一体化的设计思想,都使具有在种类繁多、功能多样的无人机领域获得广泛应用的潜力。设计了一种碟形升力体,并对其低速气动性能进行了风洞试验研究,获得了其升力、阻力、升阻比特性和静稳定特性的试验数据,并对其进行了分析。试验结构表明,碟形升力体具有较好的气动性能,已经具备一定的实用性。还以碟形升力体的研究结论为依据,对低速升力体的特点及其在无人机领域的应用前景进行了分析和论述。
Lifelike body layout is common in the design of spacecraft and is rarely used in the low speed field. However, its compact layout, huge lift body area, sufficient load space and wing-body integration design all make it possible to have a wide range of applications , The versatility of the UAV field has been widely used potential. A disc-shaped lifting body was designed and its low-speed aerodynamic performance was studied by wind tunnel test. The test data of its lifting force, drag, lift-drag ratio and static stability were obtained and analyzed. Experimental structure shows that the dish-shaped lift body has good aerodynamic properties, already has some practicality. Based on the research results of dish-shaped lifting body, the characteristics of low-speed lifting body and its application in the field of UAV are also analyzed and discussed.
