title: AirLoadBench: An original dataset for flight parameter-based structural load prediction

description: Aircraft structural Load Benchmark dataset (AirLoadBench) is an original benchmark dataset for Flight Parameter-based Structural Load Prediction (FP-SLP) related research that contains complete Take-Off and Landing (TOL) data for 48 flights. There are 39 flight parameters except relative time and 15 structural loads (i.e., key part strains, named Strain1 to Strain15). The flight parameters and structural loads have been aligned according to relative time with a sampling frequency of 32 Hz. The dataset was acquired from flight testing of a fighter aircraft and was desensitized to retain the authenticity of the data patterns. Each TOL data was stored as a separate CSV file (named TOL_1.csv to TOL_48.csv), with the first 40 columns of each CSV file being the flight parameters and the last 15 columns being the structural loads (in με).
