低ソニックブーム設計概念実証落下試験(D-SEND#1)の試験実施条件検討 Consideration of test condition for low-boom design concept demonstration (D-SEND#1) 牧野, 好和 冨田, 博史 本田, 雅久 橋本, 敦 Makino, Yoshikazu Tomita, Hiroshi Honda, Masahisa Hashimoto, Atsushi 第43回流体力学講演会/航空宇宙数値シミュレーション技術シンポジウム2011 (2011年7月7日-8日. 早稲田大学国際会議場) 東京 43rd Fluid Dynamics Conference / Aerospace Numerical Simulation Symposium 2011 (July 7-8, 2011. Waseda University, International Conference Center), Tokyo Japan Test conditioions for the first phase of JAXA's low-sonic-boom concept demonstration project(D-SEND#1) are considered. The purposes of the D-SEND#1 project are to validate the airbone sonic-boom measurement method and to make sure the possibillty of low-sonic-boom concept demonstration with the scaled airplane model by dive maneuver in D-SEND#2 project. For these purposes, the differences of sonic-boom signatures from two D-SEND#1 models have to be observed in the sonic-boom data measured with the airbone boom measurement system. The test conditions of D-SEND#1 drop test such as required altitude and position for the model separation, and atmospheric conditions, are defined through the sonic-boom propagation analyses of two D-SEND#1 models. These conditions are revised after the first drop test of D-SEND#1 conducted in May, 2011 at Sweden. 形態: カラー図版あり Physical characteristics: Original contains color illustrations 資料番号: AA0065207004 レポート番号: JAXA-SP-11-015 宇宙航空研究開発機構 Japan Aerospace Exploration Agency (JAXA) 2012-03-30 jpn conference paper https://jaxa.repo.nii.ac.jp/records/4376 1349-113X AA11984031 宇宙航空研究開発機構特別資料: 第43回流体力学講演会: 航空宇宙数値シミュレーション技術シンポジウム2011論文集 JAXA Special Publication: Proceedings of 43rd Fluid Dynamics Conference / Aerospace Numerical Simulation Symposium 2011 JAXA-SP-11-015 21 26 https://jaxa.repo.nii.ac.jp/record/4376/files/65207004.pdf application/pdf 2.2 MB 2020-01-16
