Abstract:

The gas dynamic structure of high altitude rocket plumes has been studied in a low density tunnel to obtain basic data on plume size and shape and to determine the extent of the mixing region between the free-stream and rocket gases. The rocket was simulated by specially designed ejectors using helium and CO2 as the gases, with conditions chosen to simulate a 100,000-lb-thrust rocket at an altitude of 80 km. Data taken included impact pressure surveys, density measurements of the free-stream and plume gas, temperature measurements, and color photographs. The last three of these were taken using electron beam techniques. The result of the study is a set of basic data. Analysis and interpretation of the data will be performed under a separate study.
