The magnitude of the induced normal force was obtained experimentally from a wind tunnel test of two-stage rocket models with both front- and tail-fin, with either front- or tail-fin, and without any fin. The test was performed at M∞ = 0.5 ~ 0.95 and 1.5~2.5, and the induced normal force in this region was about 30%, at maximum, of the normal force which acts on the entire model. The variation of the induced normal force with bank angle difference between front- and tail-fin was also obtained from wind tunnel tests of a roll-controllable rocket model at M∞ = 0.50 ~ 1.20. Those results were compared with predictions based on the strip theory. This simplified theory succeeded in giving approximate magnitude and Mach number dependence of the induced normal force ; however, it is not sufficient for precise prediction., 資料番号: NALTR0814000, レポート番号: NAL TR-814}, title = {小型二段式ロケットの前後翼間の空力干渉による垂直力について}, year = {1984} }
