An approximating expression for the maximum force acting on the load cell was obtained from the mathematical model and its results agreed well with experimental values. The prediction of the thrust transient was made by using a mathematical model and four alternative methods, and each of their features and problems was described.0389-4010https://jaxa.repo.nii.ac.jp/?action=repository_action_common_download&item_id=44893&item_no=1&attribute_id=31&file_no=1資料番号: NALTR0638000レポート番号: NAL TR-6382020-01-29
