SUMMARY:Trajectory Planning and Guidance for Civil Autonomous Aerial Refuel
 ing
DESCRIPTION:Lecturer:Alexander Tsukerman\n Faculty:Technion Autonomous Syst
 ems and Robotics Program (TASP)\n Institute:Technion – Israel Institute 
 of Technology\n Location:Classroom 165\, ground floor\, Library\, Aerospac
 e Eng.\n Zoom: \n Abstract: \n Details: \n Civil aerial refueling is a fut
 uristic concept that was proposed for reducing the environmental impact an
 d improving the efficiency of long-haul air transportation.  It will allo
 w a passenger aircraft (the Receiver) to take-off with much less fuel than
  required to fly the whole route. Dedicated Tanker aircraft will further j
 oin the Receiver along its route and transfer the required amount of fuel 
 to complete the mission. In such scenario\, the Receiver flies along its o
 riginal route while the Tanker aircraft is responsible for the execution o
 f the approach maneuver prior to the deployment of the docking equipment. 
 To ensure smooth and safe aircraft rendezvous\, automation is becoming a n
 ecessity.\nIn this talk\, two guidance laws to achieve rendezvous between 
 the Tanker and the Receiver will be presented. Both guidance laws were dev
 eloped using linear quadratic optimal control theory to impose zero termin
 al relative position\, zero terminal relative flight path angle\, and zero
  terminal acceleration. The first guidance law was designed as an outer lo
 op based on a first-order lag model of an inner closed loop airframe respo
 nse. Analytic solution for this guidance law will be presented and compare
 d to previously obtained guidance laws. The second guidance law was develo
 ped as a single loop autopilot-guidance controller\, which is based on a m
 ore detailed airframe model\, using full state feedback. We will demonstra
 te\, using a detailed\, nonlinear\, six degrees of freedom simulation\, th
 e ability of both guidance laws to steer the Tanker aircraft to rendezvous
  with the Receiver. The performance of both guidance laws will be presente
 d separately\, for each plane of motion\, in terms of the ability of the g
 uidance law to shape the aircraft trajectory while inducing small variabil
 ity in control surface deflections. The comparison study\, carried out for
  a large set of design parameters using numerical simulations\, indicated 
 that the overall performance can be improved by applying each guidance law
  for a different plane of motion.
