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.
