Vortex Wake Turbulence. Flight Tests Conducted During 1970

Abstract

The report covers flight tests conducted by the FAA, NASA, and the Boeing Company during 1970 to determine the characteristics intensities, and persistence of trailing wing tip voltices generated by typical transport aircraft and to investigate their effect on other aircraft encountering the vortices. Test methods involved in-flight penetration of vortices by instrumented aircraft and fly bys of instrumented towers equipped for (smoke) vortex visualization. Resulting data depicts vortex vertical and lateral movements, vortex dimensions, and tangential velocities. Data also includes induced roll rates and 'g' forces experienced by encountering aircraft. Vortex characteristics and related vortex avoidance recommendations are summarized.
