Description: |
A series of flight tests using a Boeing 727 jetliner was conducted in 1973-1974 at the NASA Flight Research Center (FRC), after 1976 the Dryden Flight Research Center, to study the effects of wake vortices emanating from the trailing edges of the wings. The NASA study in conjunction with the Federal Aviation Administration (FAA) was in response to the hazards being encountered when small aircraft trailing behind new large jumbojets experienced “upset” problems. The Boeing 727 was equipped with smoke generators for visual tracking of the wing wake vortex trail. The wing wake vortex trail was probed to measure its force and effects, by specially instrumented chase aircraft--a PA-30 and/or an F-104, or Lear Jet. The effect of wing vortex on two different airport landing glide slopes, one (normal) of 3 degrees and a second, steeper 6 degrees approach, were also studied. These tests helped to define vortex drift and dissipation near the
runway for different meteorological conditions and glide slopes. |
