Because of ever-stricter regulations on noise production, it has become more difficult for airports to expand. A ground-based propulsion system is presented that allows airplanes to accelerate to higher liftoff speeds, increase their climb rate, and thereby reduce their noise footprint. This system has been sized for airplanes with a maximum takeoff weight of 90 t or less. The system consists of a shuttle, which is magnetically propelled by a linear motor. The shuttle provides a propulsion force of 227 kN, which is transferred to the airplane via a launch bar of 4.5 m. This bar connects to the keel beam of the airplane, ahead of the most forward position of the center of gravity. To assess the effect on noise, fuel consumption, and field length, six different takeoff scenarios were conceived and analyzed using a numerical simulation model of the system. Three of these scenarios included an increased liftoff speed of 100 m/s. Results show that, depending on the takeoff scenario, a 20% reduction in awakenings is possible for a single departure from Amsterdam Airport Schiphol. Furthermore, alternative takeoff scenarios show a possible 60% reduction in fuel burn during the takeoff phase or a 20% decrease in required takeoff field length.
