在实验工作期间获得的信息包括隔热罩性能的飞行数据、支持该实验的地面测试数据，以及分析结果和实验结果的比较。飞行结果是从1978年12月9日进入金星大气层的四个“先驱者 - 金星”进入探测器的隔热罩上的仪器获得的。地面测试包括在等离子体射流设备中进行的实验、隔热罩材料热性能的测量，以及隔热罩材料分解动力学和成分的测定。分析包括实验结果的比较以及基于理论模型对材料性能的计算。
Information obtained during work on the experiment includes flight dat.a on heat-shield performance, data from ground-based tests in support of the experiment, and comparison of analytical and experimental results. The flight results were obtained from instrumentation on the heat shields of the four Pioneer-Venus entry probes which entered the atmosphere of Venus on December 9, 1978. The gr-ound-based tests include experiments in plasma-jet facilities, measurement of the thermal properties of the heat-shield material, and determination of the decomposition kinetics and composition of the heat-shield material. The analysis includes comparisons of experimental results and computations of the material performance based on a theoretical model i ng .
