Therefore, it was determined that in order to prevent any trim drag increment, wind tunnel testing acquire data on the stabilizer control effectiveness for the optimum center of gravity position should be conducted in 1993. Results of wind tunnel testing in 1993 are summarized as follows: (1) the stabilizer control effectiveness was acquired and the optimum center of gravity was obtained; (2) the maximum lift to drag ratio of 7.2 at M = 2.0 (with trim, corrected to actual size) was obtained; and (3) it could be confirmed that the longitudinal stability compensation control was effective for improvement of lift to drag ratio. As a result of the 1993 tests, the lift to drag with trim could be acquired by stabilizer control effectiveness at supersonic cruise speed. Hence, it was determined that the spillage phenomenon in front of the nacelle (refer to the oil flow testing results in 1992) that was considered to be a cause of drag increment, should be investigated in 1994 in order to improve lift to drag ratio. Results of wind tunnel testing in 1994 are summarized as follows: (1) it is considered that the oil flow pattern in front of the nacelle is not caused by the spillage but rather by the complicated interaction between the shock waves from the nacelle and the boundary layer on the wing under surface. (a) No essential change of oil flow pattern can be seen with various diverter heights and it can be concluded that the spillage is a small amount even with the original diverter height judging from the mass flow ratio of the nacelle internal flow. (b) As the oil flow results in the wind tunnel testing are compared with the structure of the flow field for a wedge mounted on a flat plate at supersonic speed, it can be concluded that the oil flow pattern in front of the nacelle is due to the interaction between the shock waves from the nacelle and the flat plate boundary layer; and (2) little effect on the drag of the complete aircraft with various azimuthal angles of nacelle is obtained in this wind tunnel testing.", "subitem_description_type": "Other"}]}, "item_5_description_32": {"attribute_name": "資料番号", "attribute_value_mlt":

内容記述 | Results of wind tunnel testing in 1992 are summarized as follows: (1) the basic aerodynamic characteristics of a complete aircraft at supersonic speed was obtained and the maximum lift to drag ratio of 7.3 (with no trim, corrected to actual size) at M = 2.0 was acquired; (2) the neutral point at supersonic speed moves backward approximately six percent in comparison with that at subsonic speed; and (3) oil flow testing around the nacelle at supersonic cruise speed shows that spillage occurs at the air intake. Therefore, it was determined that in order to prevent any trim drag increment, wind tunnel testing acquire data on the stabilizer control effectiveness for the optimum center of gravity position should be conducted in 1993. Results of wind tunnel testing in 1993 are summarized as follows: (1) the stabilizer control effectiveness was acquired and the optimum center of gravity was obtained; (2) the maximum lift to drag ratio of 7.2 at M = 2.0 (with trim, corrected to actual size) was obtained; and (3) it could be confirmed that the longitudinal stability compensation control was effective for improvement of lift to drag ratio. As a result of the 1993 tests, the lift to drag with trim could be acquired by stabilizer control effectiveness at supersonic cruise speed. Hence, it was determined that the spillage phenomenon in front of the nacelle (refer to the oil flow testing results in 1992) that was considered to be a cause of drag increment, should be investigated in 1994 in order to improve lift to drag ratio. Results of wind tunnel testing in 1994 are summarized as follows: (1) it is considered that the oil flow pattern in front of the nacelle is not caused by the spillage but rather by the complicated interaction between the shock waves from the nacelle and the boundary layer on the wing under surface. (a) No essential change of oil flow pattern can be seen with various diverter heights and it can be concluded that the spillage is a small amount even with the original diverter height judging from the mass flow ratio of the nacelle internal flow. (b) As the oil flow results in the wind tunnel testing are compared with the structure of the flow field for a wedge mounted on a flat plate at supersonic speed, it can be concluded that the oil flow pattern in front of the nacelle is due to the interaction between the shock waves from the nacelle and the flat plate boundary layer; and (2) little effect on the drag of the complete aircraft with various azimuthal angles of nacelle is obtained in this wind tunnel testing. | |||||
