The e-Sling is based on the Sling TSi build by Sling Aircraft pty. Ltd. from Johannesburg, South Africa. Thus the e-Sling has familiar good handling, high versatility and stays close to the Kit aircraft market. With the modular battery system, innovative cooling, optional range extender and the electric motor developed with e+a the e-Sling is an one of a kind electric airplane.
Aircraft
Range: 250 km
span width: 10.5 m
MTOW: 950 kg
cruise veloc.: 160 km/h
passengers: 4The e-Sling has a range of 250 km, with optional range extender up to 350 km can be reached. To increase the range we increased the span width to 10.5 m. This will enable more efficient travel for 4 passengers at 160 km/h. The e-Sling keeps the maximum take-off weight of 950 kg, to ease the certification.
Battery
Capacity: 50 kWh
Weight: 240 kg
Cells: 21700
Our battery has a capacity of 50 kWh and is housed in the wings, instead of the petrol tank, and in the engine compartment. For the main battery and the range extender, 21700 Energy cells of the latest generation are used, cooled with our innovative cooling system.
Electric motor
power (max): 110 kW
power (cont.): 45 kW
weight: 20 kg
coefficent: 5.7 kW/kg
To meet the special needs of an elctric aircraft the motor will be designed by the students. The electric motor will achieve 110 kW maximal power for the start and 45 kW continues power during the cruise.
Modifications on the Sling TSi
The e-Sling is based on the Kit aircraft SlingTSi developed by Sling Aircraft from South Aircraft, who committed early as partner in the project and enabled us with their support to carry out this project.
The Sling TSi was modified at multiple spots to fulfill the demands of the electric drive train. Development engineer and co-founder A. Weiser unterstützte dafür den Flugzeugbauer Sling Aircraft aus Südafrika vor Ort bei der Planung der neuen Strukturen.
