Powervision is participating at leading trade show XPONENTIAL 2016 in New Orleans as part of a trade-show co-operation with German engine manufacturer 3W International. The company introduces its DRAGONFLY DF M35 remotely piloted aircraft systems (RPA) to the international professional public at 3W International's trade-show stand.
All of the helicopters are based on the Flettner intermeshing-rotor principle in which two rotors arranged in parallel are responsible for the helicopter's upward and forward drive. A tail rotor is thereby rendered unnecessary. Flight behaviour is very safe, quiet, and nearly vibration free due to the missing tail rotor.
Both the DRAGONFLY DF T20 and the DRAGONFLY DF T50 are driven with turbines, which are rated at 6kW and 11kW respectively. This enables the DRAGONFLY DF T20 to transport 20kg and the DRAGONFLY DF T50 50kg at a maximum speed of 100km/h. Flight time here is at most one hour. However the DRAGONFLY DF T50 can also be operated in the air for a maximum of four hours with the help of auxiliary tanks.
A third model, the DRAGONFLY DF M35, is equipped with a two-cylinder boxer engine from 3W International. The DRAGONFLY DF M35 can transport at most 35kg with a maximum speed of 100km/h. As with the DRAGONFLY DF T50, the DRAGONFLY DF M35 can extend its deployment time to four hours with auxiliary tanks.
