Motor cooling is handled via a small electric fan forward of the rudder pedals, an air vent in the nose cone that allows outside air to help cool the motor (and the cockpit), and 3 electric fans on the shelf behind the pilot's seat to cool the controller. When the batteries get low, warnings go off on the FCU, and I would then throttle back and turn off the FES. There is no automatic shutdown of the FES which allows the pilot to keep the FES running if there is an emergency situation. Thx - Renny







On our latest instalations, we manage to arrange cooling also without electric fan infront of pedals. Motor itself has bigger centrifugal ventilator at back side!

Luka,



It sounds like a number of incremental changes have been made to the FES system that have not yet been posted to your web site. Could you write a post detailing these changes and perhaps also let us know what's coming in the near future? Thanks,



SLB





Luka:



Since the prop now automatically stops in same position each time, does

this mean that the cross section shape of the fuselage at the nose no

longer has to be circular, but instead could be oval like on many

gliders? This would require the spinner to be oval -- does an oval

spinner shape present problems?



I second the idea of better information in one place on the web page.

Right now, anyone wanting accurate information must be a sleuth who

reads multiple webpages, who reads a PDF brochure, and who peruses RAS

postings by Luka and others. Sherlock Holmes, we need you!


Dear Greg,

Your thinking is correct! For Silent we are using now already slightly oval - eliptic shape of spinner at fuselage front cut. Small amount of ovality does not present any problem, but need to explore possibilities of even higher ovality...
We will try to publish latest data and achievements on our website more regulary. Now pilots can sigh in for our newsletter, where those informations will be published when it will be apropriate.
