内容記述 | Recently fundamental studies on the next generation SST (Supersonic Transport) system have been made worldwide. One of improvements in the aerodynamic characteristics investigated is active flow control. In this paper, the possibilities for simulating the authors' cases of the active control under the present flow condition are explained. The improvements in aerodynamic characteristics of an arrow wing have been experimentally attempted by means of lateral blowing in a low speed flow. A modified arrow wing, which is one of the baseline configurations of the prototype of the next generation SST, was selected for the experiments. The testing model consists of a cylindrical body with a conical apex and a modified arrow wing with an aspect ratio of 1.91. The lateral blowing is realized by injecting a pair of sonic jets blowing in opposite directions away from each other parallel to the trailing edge of the wing. The experiments were performed in the ISAS (Institute of Space and Astronautical Science) transonic wind tunnel. The results show that the lift coefficient C(sub L) and lift-drag ratio L/D is increased with lateral blowing under subsonic flows, while drag coefficient C(sub D) slightly increases under both subsonic and supersonic flows. It is suggested that the lateral blowing can be useful for the improvement in aerodynamic characteristics of the arrow wing under transonic flows as well as subsonic flows. | |||||
