Variable sweep allows aircraft to fly throughout broad regime of speed and altitude efficiently without excessive power requirements; tailored lift drag, improved ride quality, lessening of fatigue damage, and reasonable control sensitivities are advantages; however, variable geometry multiplies possibilities requiring consideration in development of repeated load spectra for fatigue design, analysis, and tests; four different concepts for wing pivot mechanisms and failsafe considerations are presented; it is concluded that flight loads testing, dynamic response flight testing, and laboratory static and fatigue testing are all complicated by addition of variable geometry feature.
