• Note (General): 主翼に後退角と上反角をつけ、水平尾翼に前進角と下反角をつけて、両者を結合した菱型結合翼機は新しいタイプの航空機として風洞試験や数値解析が行われている。菱型結合翼機の基本的な空力特性を得ることを目的として、水平尾翼の翼幅および主翼との結合位置を変化させた4形態の菱型結合翼機について低速風洞試験を行った。その結果、結合翼機では主翼の吹下ろしと剥離が全機空力特性に大きな影響を与えること、ならびに、主翼と水平尾翼の翼端を重ねた形態では揚力低下や早期失速を招くことがわかった。; Low-speed wind tunnel tests were conducted on four types of joined-wing aircraft models. Various ratios of horizontal tail to wing span were employed (40 percent, 60 percent and 100 percent.), and the leading-edge at the tip of horizontal tail was joined to the trailing-edge of the wing for three configurations. In addition, in one configuration the tips of the horizontal tail and the wing were overlapped using the 100 percent ratio. The horizontal tail has minus 22 deg dihedral and minus 25 deg sweep angles (25 percent chord line). And the main wing has respectively corresponding angles of 10 deg and 40 deg. The results indicated that the area and location of horizontal tail significantly effect the aerodynamic characteristics of the joined-wing aircraft.; 資料番号: AA0004184000; レポート番号: NAL TR-1167
