摘要

尽管与制造大型可展开天线反射器相关的理论、设计和实验研究已经开展了相当长的时间,但这一领域仍然是人们关注的热点,具有良好的应用前景。一个例子是欧洲空间局(ESA)关于创建一个15米可展开空间偏移反射器的合格改型的计划。应该说,在欧空局通过关于实施该方案的决定时,格鲁吉亚已经制造了一个直径为7米的可展开空间反射器,并于1999年根据格鲁吉亚-俄罗斯联合方案在“和平号”轨道站上成功地进行了测试。格鲁吉亚空间结构研究所,继续为俄罗斯的大型空间可展开系统、可变形空间和地面结构开发新的设计原则,专著,格鲁吉亚-德国-列支敦士登,1995年。在本文中,我们描述了一种全新设计的空间天线的发明,用于对称和非对称射电望远镜,这是由格鲁吉亚的设计师团队由E. Medzmariashvili教授领导的。其新颖之处在于,通过环形和肋伞形系统的综合,获得了新的工程技术效果。特别是,连接受电弓的主要杠杆的中心铰链是不对称的。由于这种不对称的布置,在部署过程中,控制台沿着包的纵轴折叠,并连接相邻的部分,从中心到外围沿径向移动,同时以伞状的方式部署。

New variant of the deployable ring-shaped space antenna reflector
Despite that theoretical, design and experimental studies connected with the creation of large deployable antenna reflectors have already been carried out for quite a long time, this area still remains of lively interest and has good application prospects. An example is the program of the European Space Agency ESA on the creation of a qualified variant of a 15 m deployable space offset reflector. It should be said that by the time the ESA adopted a decision on the implementation of this program, a deployable space reflector 7 m in diameter had already been created in Georgia and, in 1999, this space reflector was successfully tested aboard the orbital station “Mir” according to the joint Georgian--Russian program.Georgian Institute for Space Constructions, continues developing new design principles for large space deployable systems Transformable Space and Ground Structures in Russian, A Monograph, Georgia--Germany--Liechtenstein, 1995.In the paper we describe the invention of an absolutely new design of a space antenna for symmetric and nonsymmetric radio telescopes, which has been developed by the team of Georgian designers headed by Professor E. Medzmariashvili.The novelty consists in that new engineering and technological effects we obtained by synthesis of ring-shaped and rib-umbrella type systems.In particular, the central hinge that connects the main levers of the pantograph is arranged asymmetrically. As a result of this asymmetrical arrangement, during deployment the consoles folded along the package longitudinal axis and connecting the adjacent sections move in radial directions from the center to the periphery and, simultaneously, deploy in an umbrella-like manner.
