Abstract
A detailed understanding of supersonic free jets and the underlying flow phenomena is key to many technical applications such as exhaust nozzle flows of aircraft or rocket engines, or for well-defined test cases in the validation process of numerical setups. In this paper, we suggest an uncooled, low-cost pitot probe made from a high perfomance metall alloy. The paper describes the design of the probe, the obstacles during the manufacturing process and presents validation and application cases for free jets with an inlet total temperature of up to 1100K.
