AbstractD-SENDプロジェクトは, ソニックブームの低減を目的とした空力設計技術を飛行実証するための飛行実験である. D-SEND#2では, 有翼機体を高層気球を用いて高度約30kmから分離し, 地上に設置したソニックブーム計測システム(BMS)にてソニックブームを計測することを目的としている. 本稿では, D-SEND#2の誘導制御系を対象に, 飛行実験に向けて実施した様々な観点からの評価について報告する.
This report is concerned with evaluation of GNC systems for D-SEND#2. D-SEND is a project to demonstrate a low sonic boom aerodynamic design concept, and the objective of D-SEND #2 flight test is to measure a sonic boom which is generated by a test vehicle at prescribed flight conditions. In this flight test, an unpowered test vehicle is lifted to an altitude of 30km by a balloon from which it then separates. After the separation, the vehicle's on-board flight control computer selects a target Boom Measurement System (BMS) according to the separation point. The vehicle then autonomously flies to the selected BMS and establishes prescribed sonic boom measurement flight conditions. Since it is required to achieve mission objectives at the very first flight in such a flight testing using a balloon, evaluation of mission success chance is mandatory adding to that of controller stability. It is also important to establish operational criteria for various anomaly cases. Some customized evaluation are also carried out to asses various risks in the flight test. This report describes a comprehensive evaluation method for GNC systems of D-SEND #2.
