Fixed Path Pull-In/Pushback Trajectories for Airliner Ground Transport

Abstract

The process of ground movement of airplanes about an airport is currently accomplished with a combination of engine thrust and ground vehicles. Minimization of on-ground fuel usage of airlines and reduction of ground support equipment hazards are desirable goals for airlines and airports. Fuel economy, pollution and noise as well as safety improvements are sought by a variety of technologies and operational approaches. In this research, an investigation is conducted into the range of potential paths for pulling airliners into their destination gates and pushing them back for engine start on departure through fixed path nose gear tracks. The feasibility of fixed paths is analyzed for this application and improved trajectories are identified. A kinematic model is developed to generate the trajectory of Main Landing Gear, wing and tail tips of an aircraft. Benefits and risks of system integration also discussed.
