Navy Lynn F414 Test results

25KHz Temperature measurement

Eight milliseconds of temperature data recorded at 25 kHz (40 microseconds/pt) at an engine exit while in after burner mode. The peak-to-peak variation of the data is 625 K.

 

100KHz Temperature Testing

One second of temperature data recorded at 100 Hz (10 milliseconds/pt) at an engine exit while in after burner mode. Note the repeating patterns of temperature variation.  The peak-to-peak variation of the data is 50 K.

Throttle position ramp testing

Temperature data recorded over about 2 ½ hours at an engine exit location while the throttle position was varied incrementally between low and high power positions. The vertical axis includes 50 degrees per division.
