Flight Spectra Development for Fighter Aircraft

Source

A method is presented for deriving realistic flight-by-flight stress spectra which are valid for any point in the structure of fighter or attack type aircraft. This method uses regression equations to define the relationships among stresses and flight parameters. The statistical distributions of aircraft motion parameters are derived and defined in multi-parameter response tables. These tables are combined with assigned mission profile data to establish all of the required flight parameters which are used in the regression equations to develop stress spectra. These spectra then are sequenced into a flight-by-flight order which can be used as input to a damage determination model or as a load program for laboratory testing.
