摘要

In the framework of the European project MOREandLess, under Horizon 2020 program, this work aims to contribute to the growing research on supersonic aircraft for commercial use. Through collaboration between ISL and CIRA, a series of outdoor investigation activities were conducted to produce a large amount of high-quality experimental data suitable for both characterizing the sonic boom and for validating or refining existing and novel analytical methods for sonic boom prediction. The sonic boom is the massive thunder-like noise produced when an aircraft breaks through the sound barrier, representing one of the most persistent challenges of the supersonic regime. To address this issue, considerable efforts were devoted to developing various demonstrators and evaluating their impact on the intensity of sonic booms. A first test campaign, consisting of five free-flight tests, was carried out on October 4th and 5th, 2022, at the ISL firing range in Saint-Louis, France. During these tests, a reduced and slightly modified version of the STRATOFLY MR3 vehicle was launched using a 91 mm powder cannon, reaching an initial Mach number of approximately 4.7. To capture the sonic boom, ISL and CIRA deployed various types of sensors in the field. The collected data was subsequently processed to generate a sonic boom directivity diagram for the model and a comparison with Whitham’s modified linear theory predictions.
