Path planning of helicopter flight with borne detector based on TDLAS for pipeline leaks detection

From the detection sensitivity of the detector and the detection laser autonomous positioning the pipeline to ensure the detection pipeline not missed, the path planning of the helicopter was given. The flight range at the joint of two pipe sections of carrier aircraft was determined. Concerning the detection sensitivity, the relationship between the flying height and the distance due to the flying deviation from the pipeline was given. The results show that the flying height is less than 110 m and the flying deviation distance from the pipeline is less than 45 m respecting the detection factors. The flying helight is reduced as far as possible under the premise of flight safety.
