The A.E.G. helicopter, designed by R. Schmidt in 1933, bore a striking resemblance to the Petroczy-Karman aircraft utilized during World War I.
To ensure stability, the A.E.G. was secured to the ground by a system of three tethering cables, allowing it to function as an observation post or provide aerial support when necessary.
The co-axial contra-rotating two-bladed rotors were powered by an electric motor positioned between them.
These rotors received power through the three anchoring cables, which were attached to girder-type arms fixed above the upper rotor.
These tethering girders provided support for the observer’s cabin.
In the event of engine failure, the observer could escape using a parachute propelled into the air by a powder charge.
To transport the helicopter to its designated location, a specialised truck equipped with a launching stand and control desk was utilised.
Despite successful trials, it seems that the AEG helicopter was not adopted for military use, likely due to the impracticality of sourcing a significant electric current supply.
