项目摘要

低高度を数年継続飛行することで空の基地局となる衛星航空機の実用化が期待されている．従来航空機と異なり，極軽量柔軟な衛星航空機は静的大変形形状によって周波数特性・動特性が激変する．衛星航空機の早期実現には大変形を考慮した数値モデル（非線形運動方程式）による静解析・周波数解析・動解析という一連の解析が必要になる．非線形性を任意に移動させ，静解析・周波数解析・動解析いずれに対しても容易に適用でき，高い解析性能を発揮する【非線形移動型モデリング法】の構築を目的とし，２年目は以下の３点に取り組んだ．①静解析モデルの精度実証：東北大学・流体科学研究所の風洞装置を用いた．鉛直に固定支持した平板翼模型に対して，迎角と流速を変更した場合の変形量をレーザ変位計で計測した．風洞実験結果と解析結果は良好に一致した．②動解析モデルの精度実証：東北大学・流体科学研究所の風洞装置を用いた．鉛直に固定支持した平板翼模型に対して，先端にワイヤを貼付した．そのワイヤを切断することで，風洞内において模型に振動を発生させた．実験結果と解析結果は良好に一致した．この実験成果をJournal of Sound and Vibrationで発表した．③【ジョイントパラメータ】という定式化法を提案し，衛星航空機の静解析用歪モデルにおいて，操作舵面などのジョイント部の効率的な表現を可能にした．【ジョイントパラメータ】の基礎理論をJournal of Sound and Vibrationで発表した．

For several years at low altitude, we are looking forward to the use of satellite aircraft at low altitude. it's coming to the aviation industry. The dynamic characteristics of the wave number of the flexible satellite aircraft are very exciting. In the early stage of the satellite aviation machine, the dynamic characteristics of the wave number of the flexible satellite aircraft are very exciting. The satellite aeronautical machinery in the early stage showed that the wave number of the satellite aircraft was very large. (non-shaped motion equation) dynamic analysis of the static analysis of the cycle number analysis of the static cycle number of the satellite aircraft is necessary for the analysis of the necessary wavenumber. Non-shape-sensitive arbitrary moving machine The static analysis cycle number analysis activity analysis system is easy to use, and the high performance analysis method [non-linear movement model] has a high resolution performance. In 2 years, the following 3 points are selected. 1 static analysis of the accuracy of the hole device of the Institute of fluid Science of Peking University. Fixed support for flat wing model The angle of attack velocity is in line with the angle of attack, the velocity is in line with the shape, the position is calculated, and the hole is calculated. The analytical results are in good agreement with each other. 2 the accuracy of the dynamic analysis is used by the Institute of fluid Science, Peking University. the flat wing model is fixed to support the flat wing model, and the front end is cut off. The vibration of the model in the tunnel is good and consistent. The results of the analysis are good and consistent. The results of the test are in the Journal of Sound and Vibration table. 3. The proposed method is proposed for the static analysis of satellite aircraft. the static analysis of satellite aircraft is based on the error analysis method. The operation of the rudder surface may show that the rate of the rudder surface is very high. [the operation of the rudder surface] is based on the basic theory of Journal of Sound and Vibration.
