  • Experiments were conducted in a scramjet direct-connected wind tunnel facility with a combustion heater,which supplies Mach 2.7 airflow with a total temperature of 1 337 K.The drags of struts with different heights(H=37.5,71mm) and sweepback angles(0°,30°,45°) were studied by a thrust-measuring system.Experimental results in cold flow indicate that,the drag of strut rises with increase of height and declines with increase of sweepback angles.The drags of struts under combustion condition of different fuel equivalence ratios were investigated.It is found that the drag of strut under combustion condition is less than that in cold flow,and declines with increase of fuel equivalence ratio.
