Unmanned aircraft for telecommunications or other scientific purposes

用于电信或其他科学目的的无人飞艇

Abstract

The invention relates to an unmanned aircraft for telecommunicative or other scientific purposes, which s stationed in determined height, in particular in the stratosphere. The aircraft comprises a gas-filled balloon (11) carrying a platform (10) and means for maintaining the platform position relative to the ground. The balloon (11) carrying theplatform (10) is disposed in the interior of an external balloon (12) of aerodynamical shape, particularly in the stratosphere. At least one low or high pressure insulation chamber (20; 20'; 20'') filled with a medium is arranged between them and encircles the inner balloon (11). The medium used in the insulation chamber is a gas having a low thermal conductivity. The negative effects of the temperature differences are largely compensated so that the inner balloon can be produced from a lighter and cheaper material, thereby increasing durably its longevity.
无人飞艇,用于电信或其他科学目的以驻留在预先确定的高度上,特别是驻留在平流层中,它包括载有平台(10)且充有气体的气球(11),以及用于相对地球保持平台位置的装置。该载有平台(10)的气球(11)被布置在特别在平流层中具有空气动力外形的外部气球(12)中。在它们之间围绕内部气球(11)形成至少一个用介质充注的低压或高压隔离腔(20;20’;20”)。应用具有低热导率的气体作为用于所述隔离腔的介质。温差的负面效应得到尽可能平衡补偿了,因此内部气球可以用较轻的和较便宜的材料制造,并且它的使用寿命被有效地提高。
