| Abstract: | The results of wind tunnel tests of upper arm fo a 1/10 scale model crewman and ejection seat at transonic-supersonic speed were presented in. the paper. Drag and lateral forces on upper arm were measured at freestream Mach number from 0.5-2.04 and incident angle from 10°-to 20°.The aerodynamic characteristics of upper arm in the attitutes of grasping side and seat pan ejection handle initiator were obtained. Aerodynamic data on upper arm were compared under the conditions with and without cloth. The paper presents the important aerodynamic data for determining tolerance of human upper arm of wind-blast and designing a airciew windblast protective device. |
