The Measurement of the Boeing 707 Trailing Vortex System Using the Tower Fly-By Technique.
Abstract
The results are presented for a series of low-altitude (160 - 240 feet above ground level) flight tests performed at the National Aviation Facilities Experimental Center (NAFEC), Atlantic City, New Jersey, in which the trailing vortices of the Boeing 707 airplane were investigated using a 140-foot tower instrumented with airspeed, velocity, direction, temperature, and humidity sensors. Flow visualization was employed and motion picture records made. The airplane was tracked by the NAFEC Phototheodolite Facility. The data presented consist of plots of vortex tangential velocity distribution, peak tangential velocity as a function of time, airplane configuration, windspeed, and airplane altitude in proximity to the tower, vortex descent rates, lateral transport velocities, and specimen time histories of the velocities measured by individual sensors.
