Résumé

The Japan Aerospace Exploration Agency (JAXA) is actively conducting supersonic transport research toward the realization of civil supersonic aircraft. Technology that precisely measures sonic booms is essential to demonstrating JAXA’s sonic boom reduction concept in the planned drop test of a research aircraft. This is a part of the D-SEND Program (Drop Test for Simplified Evaluation of Non-Symmetrically Distributed sonic boom). Capturing detailed multichannel sonic boom histories to validate aircraft design concepts that reduce sonic booms, which is necessary for next-generation supersonic transport. The first step was the development of a ground based real-time monitoring and data-logging system that measures sonic booms indoors and outdoors as well as the resulting vibration of the windows and walls of the test buildings at the Northern European Aerospace Test range in Sweden. The ground-based measurement system is being expanded to include an aerial measurement system distributed at altitudes up to 1,000 m to reduce the effects of atmospheric turbulence. This system will be based on stand-alone computers controlled via wireless LAN distributed aloft for making high-accuracy audio frequency measurements. The objective is to accelerate the development of civil supersonic aircraft by demonstrating the low-boom design technology in planned drop tests.
