摘要

In this Technical Note, is shown that relationships exist between flying qualities levels 1, 2 and 3 and flight conditions expressed in terms of Mach numbers, altitudes and angles-of-attack for the F/A-18 SRA (System Research Aircraft). These relationships are helpful in detecting if derivatives are well calculated for flight tests intermediate conditions. The stability and control derivatives were calculated at NASA Dryden Flight Research Center DFRC laboratories for a number of 52 flight test conditions for the longitudinal and lateral aircraft motion. Flight tests were considered at Mach numbers between 0.3 and 1.3, at altitudes between 1,000ft and 40,000ft and at angles-of- attack vary between 1° and 10°. Following two methods were used to calculate the characteristic system eigenvalues: the approximate method and the exact method.
