Aluminium grooved heat pipes (AGHP) applied for space craft's thermal control systems are considered in the report. Inside AGHPs capillary structures have been optimized in order to make maximum capillary head at minimal hydrodynamic resistance taking into account technological ability of their manufacture. Experimental results of the thermal performances (thermal resistance and maximum heat transfer...
The paper presents results of thermal vacuum testing of engineering model of nano-satellite PolyITAN-2-SAU of NTUU “KPI” in a vacuum chamber TVC-0.2. The aim of the test was to check the operation of all nano-satellite systems in the simulated deep space conditions for participation in the international mission QB50. Tests have shown that defined impact of the space factors do not cause any problems...
The previous researchers have developed a variety of liquid thermal solar collectors designs for water heating. It was reported by the other authors, that metal heat pipes applications to liquid solar collectors, especially to evacuated glass tube ones, is an efficient solution for water heating plants. However, the majority of thermal solar collectors do not meet the requirements on small weight,...
