Compared with common airliners, High/Medium
Altitude Long Endurance (HALE/MALE) RPAS are lighter and
have larger wingspan. Therefore RPAS will be extremely sensitive
to vortex interactions with larger airliners, not only during
departures and arrivals, but also at medium and high altitudes
during the en-route phase. The extent of this sensitivity shall
be investigated in order to determine safe levels of separation
and come up with feasible maneuvers to avoid the effect of
wake vortex under the assumption that the RPAS may become
unrecoverable by the autopilot. For this reason, the objective
of this paper is to model the generation of en-route vortex
and quantify its impact into the airworthiness of a potentially
conflicting RPAS. To accomplish this objective, a wake vortex
generation and encounter model will be created as a first step
to define the airliner-RPAS separation requirements due to the
airliner’s vortex. Then, vortex separation requirements will be
compared to those usually employed for separation assurance.
Conclusion will show that some current separation standards
are not conservative enough when the RPAS faces an airliner
wake vortex.Peer ReviewedPostprint (author's final draft)
