A design of the instrumented pod for the newly developed ECM(Electronic Counter Measure) pod compatibility flight test is presented. A requirement study asks the measurement of load, vibration, and aerodynamic heating. Following sensors are designed for the flight load data evaluation; 1) 3 linear accelerometers, 3 angular rate sensors, and 2 inclinometers at the center of gravity 2) 8 channel strain gages at the lugs, 3) 2 STRAINSERT $^{circledR}$ bolts to measure the tensile load. The 3 triaxial linear accelerometers are installed to measure the vibration environment and 4 thermocouples are installed. Finally, a bus monitor is installed to extract the aircraft parameters such as altitude, speed, load factor and attitude from the W-mux of KF-16 MIL-STD-1553B. All the data are recorded in digital tape by PCM(Pulse Coded Modulation) stream. The functional test assures the normal operation of the instrument pod design.???
