Abstract:

Sonic boom is a key factor affecting safety, economy, and environmental-friendliness of supersonic aircraft flight. Measuring and assessing sonic boom under real atmospheric conditions through flight tests is an important technical approach in induced problem research. The sonic boom measurement flight test is a complicated systematic engineering work, requiring breakthroughs of a series of sonic boom field measurement techniques from near-field to far-field. This paper presents an overview of sonic boom measurement flight test activities over the nearly past seventy years, and summarizes the development history and characteristics of the sonic boom flight test technology in three stages. Based on the analysis of propagation characteristics of sonic boom, the technical measurement scheme of the entire propagation path is proposed. Then, the sonic boom measurement technology by probe aircraft, aerostat and ground facilities is reviewed with emphasis on technical points, and the development trends are prospected. Finally other necessary parameter measurement methods and some key issues and future research directions of sonic boom measurement techniques of flight tests are briefly presented. Based on this, the technical development deficiencies of sonic boom flight tests in China are analyzed and some research directions are suggested.

Key words: sonic boom, sonic boom measurement, flight test, shock wave, supersonic aircraft
