E-ROP is a multi-party program using an Antares self-launching sailplane.  FES and Adventec have crafted a hybrid version of the Antares 20e with a front electric sustainer (FES) motor in place of its tall mast-mounted motor.  An incremental program, E-ROP begins by replacing the retractable unit with an FES motor on the nose.  This reduces the drag created by the motor being raised into position and simplifies operation. The FES Antares flew for the first time on April 19 with Klaus Ohlmann at the helm.  Ulrich Bronet recorded this short video. Under development since 2016, E-ROP will benefit from an advanced battery package from research partner AdvanTec GmbH.  According to the project, “The concept provides for batteries in the fuselage and wings, which have an energy capacity of 22 [kilowatt-hours] at a total take-off weight of 650 [kilograms] (1,433 pounds) MTOM (Maximum Take Off Mass).”  22 kWh is about one-fifth of a Tesla battery package and will allow up to 450 …

Antares Upgrades to RED.3 Batteries

An airplane that’s a seasoned veteran gets even better with the new SAFT RED.3 batteries.   At the Grenchen, Switzerland Electrifly-in Lange Antares spread their wings over 21 meters of display space each.  Klaus Ohlmann flew the latest E model from the manufacturer and a hybrid e-Rop from AdvanTec GmbH was on static display.  These airplanes are evolutions of the original design, which goes back to 2003.  SAFT’s new batteries will make the plane even better. Richard Van Grunsven, founder of Van’s Aircraft, granted your editor an interview in 2010 and demonstrated the motor’s operation on his Antares.  The same 42 kilowatt (56.3 horsepower) motor is retained in the current version, but batteries have become better in the last 11 years.   http://cafe.foundation/blog/richard-van-grunsvens-antares-20e/ As your editor reported then “Two carbon-fiber propeller blades attach to beautifully machined fittings on the rotating cylinder, and provide enough thrust to give the 460 kilogram (1,014 pound) ship a 4.4 meter per second (866 feet per …
