passenger aircraft with a maximum takeoff weight of 600 tonnes and is unique in its performance class. The first prototype of the vehicle is scheduled for delivery to Lufthansa LEOS at the end of 2014. In the medium term the eSchlepper will be replacing the diesel- powered tow-bar-based aircraft tugs currently in use. The eSchlepper will be more environ- mentally friendly and economical owing to its innovative electric motor. The all-wheel-drive electric vehicle will be powered by lithium-ion batteries and externally charged from the electricity grid. When necessary, the batteries can be charged during operation with the use of a fully integrated diesel motor. ity concepts for future application in vehicles used for aircraft taxiing and towing on the apron at Frankfurt Airport. The long-term goal is that aircraft will no longer taxi to a runway, parking position, or hangar under the power of their engines but with the use of an electri- cally powered aircraft tower or an electrical propulsion system integrated into the aircraft itself. eTaxi: Electrically powered landing gear for taxiing In the eTaxi project we are studying the use and technical integration of an electric motor in the main gear of short- and medium-range aircraft for all taxiing maneuvers on the apron. The system’s electrical power is generated and stored by the aircraft’s auxiliary power unit. eSchlepper: A hybrid electrically powered aircraft tug This sub-project involves a hybrid (diesel/ electric) electrically powered aircraft tug with- out a tow bar. The eSchlepper was developed by Lufthansa LEOS, a subsidiary of Lufthansa Technik, in collaboration with the Swedish company Kalmar Motor AB. Lufthansa LEOS plans to use the eSchleppers for repositioning and towing heavy long-haul aircraft over distances of up to seven kilometers between the gates and hangars (on-base tows). The eSchlepper can move even the largest Ú E-PORT AN: Into the future with electro-mobility Frankfurt Airport is Germany’s largest com- mercial airport and one of the most important hubs for air travel in the world. It is also where we are currently working with our project partners to advance the E-Port AN electro- mobility initiative. The objective is to use electrically powered vehicles for aircraft handling to reduce emissions generated during ground maneuvering. The Lufthansa Group, Fraport AG, the State of Hesse, and the Rhine-Main Model Electro-mobility Region are partners in the initiative. The future-ori- ented electro-mobility project is being subsi- dized by the German Federal Ministry of Transport, Building and Urban Development with scientific support from the Technical University of Darmstadt. On June 10, 2013, it received the “Electro-Mobility Beacon” dis- tinction from the German federal government. This award is reserved for innovations that make a significant contribution to progress in the field of electro-mobility. The Lufthansa Group’s eTaxi, eSchlepper, and TaxiBot projects involve various electro-mobil- 09 Heading for green aircraft handling: In the future, Lufthansa LEOS would like to use an eSchlepper to reposition and tow heavy long-haul aircraft.
