本文目的在于确定哪些材料能在温度变化范围为:-424°F—+2000°F,压力差为750磅/时~2的情况下,可作为在核火箭发动机喷嘴的不锈钢管上固定热电偶用的胶结剂。为此,列举了可供选用的材料的性能数据。阐述了依导热率、抗弯、抗拉和抗压强度来评价现有的和所推荐的材料的分析方法。为了将材料分类,对大约40种物质指定了性能指数。其中最有希望的材料是:ZrO_2、MgO、MgO+50％羰基铁(Carbonyl Fe)、Al_2O_3+50％羰基铁、A1_2O_3和氮化硼。
The purpose of this paper is to determine which materials can be used as a thermocouple on a stainless steel tube for a nuclear rocket engine nozzle in the temperature range of -424 ° F- + 2000 ° F and a pressure differential of 750 psi / Used cement. To this end, the performance data of the available materials are listed. The methods of analyzing existing and recommended materials in terms of thermal conductivity, bending resistance, tensile strength and compressive strength are described. About 40 substances are assigned a performance index in order to classify the material. Among the most promising materials are: ZrO 2, MgO, MgO + 50% Carbonyl Fe, Al 2 O 3 + 50% carbonyl iron, Al 2 O 3 and boron nitride.
