The Air Energy AE-1 Silent is a German self-launching ultralight sailplane powered by an electric motor. Designed and built by Air Energy, the AE-1 Silent is also marketed by Alisport of Italy, see Alisport Silent 2 Targa.[1][2]

Design and development[edit]

The Silent is a conventional composite monoplane glider with a retractable 13 kW (17 hp) electric motor driving a 1.92m propeller.[3]

The aircraft was originally marketed with a nickel–cadmium battery pack, but in 2005 this was replaced with a lithium polymer battery system that gives three times the range of the early installation.[2]
