Luka Žnidaršič  of FES (Front Electric Sustainer) directed your editor to the following.  His company displayed at Aero 2014 in Friedrichshafen, Germany during that stellar event, showing off the latest sailplane to use their integrated power system. “We are glad to inform you that during Aero 2014 we presented our new Ventus 2cxa FES. We performed installation in cooperation with Schempp-Hirth manufacturer. This is first FES system installed on German type of sailplane.   Luka adds, “We made this development in cooperation with Schempp-Hirth who also recognized potential of the FES system.  The new Ventus 2cxa FES is available for about 100.000€+VAT taxes and options.” “Pictures show more than words!” Both Luka and his father Matija started as model aircraft builders and …

Silent 2 Electro Certified in Germany

Luka Znidarsic shared this happy message this morning. “We are very proud to inform you, that the SILENT 2 Electro, equipped with our FES system, has been awarded Type Certification by the German Aero Club (DAeC). “This is the very first electric powered Ultralight sailplane certified, by DAeC. This represents a significant milestone in gliding history, which marks a new age of technology!” We hope this breakthrough in Germany encourages our own Federal Aviation Administration to review their schedule for electric aircraft certification.  Such rule making would allow sales of existing electric motorgliders and   light aircraft and encourage others to step up development of these alternatives to fuel-burning lightplanes. The Type Certificate gives some clear ideas of the technology incorporated in the very …

Sustainable Soaring

Glaser-Dirks Flugzeugbau, the German sailplane manufacturer, has introduced the DG-1001te, a two-seat, electric turbo craft that can sustain flight and even show a modest rate of climb, but is not capable of self-launching. The “turbo” designation is common on European craft that rely on a pop-up motor to maintain flight in unfavorable soaring conditions.  Following an aero-tow or winch launch, the sustainer engine is used to allow “get-home mode” operation, or to maintain altitude while the pilot searches for areas of better lift. Until recently, single- and two-cylinder Solo two-stroke engines served on many applications.  Electric motors are beginning to find favor, though, because of their ease of starting and the fact that their light weight and high power output …

FES at Friedrichshafen

The Front Electric Sustainer motor system, developed by Slovenian father and son entrepreneur team Matija and Luka Znidarsic, was on display at the E-Flight Expo, part of the larger Friedrichshafen Aero 2010 show.  Both are graduates in Mechanical Engineering from the University of Ljubljana.   This system, described in an earlier entry (“Power Up Front,” November 1, 2009), is meant to provide power for a sailplane that is launched by other means, such as an aerotow or winch.  Its light weight does not detract from the normal performance of the sailplane, but does enhance safety, with the pilot able to start the motor and power away into a modest climb if necessary to save a flight. In response to this editor’s naive questions, Luka responded, “No, there …
