Hi Jean Louis This my second modell in my life ,the first one was 42 years ago an aeroplain. Get me happy , thanks for the drawing see Atlantis folder Regards...
Dear all, This GFS-UAV has made me very interested, but I think we need to find out some basic thing first. The air flow from the propeller or blower is going...
Hi Jean Luis Thank you for the drawings. I have other motor, because i dont get rex 220/12 in my land. It is Permax Multiplex( made in germany ).17000RPM at...
Hello, I'm a new member. Can someone give a good explination about why the GFS has such a large redution in prop noise. I have spent the last 10 years ...
Dear Naudin, I do not know much about the Tesla turbine or Tesla fan, but I am trying to learn more about it. From what I have found, the Tesla turbine could...
Dear All, I have just updated the GFS-UAV N-01A project page with a lot of detailled photos and comments about the construction sequence and the electronic...
Hi Jean-Luis. I have to report that after having puting your designs in the ploter, and respecting the given scale , the resulting device has a diameter of...
Dear Naudin, I agree with you that the vortex implosion turbine used by Viktor Schauberger looks to be very complicated to make right. Maybe just to use the...
Dear Naudin, Tesla made some very efficient turbines; it was only parallel plates rotated at high speed. If the propeller was replaced with a Tesla turbine,...
Dear Naudin, I am really looking forward to your first flight. But I am even more interested in the behaviours when it is flying horizontal at a relative high...
Dear All, I have just upload the photo of the brushless outrunner motor installed on my GFS-UAV N-01A at : _http://jlnlabs.imars.com/gfsuav/gfsuavn01a.htm_ ...
Hello everybody, can you please explain how those little flippers (mouse ears) are driven by the servo? The graphics by you, Mr Jaudin, only show the...
Dear All, For your information, see below : << 15 March 2006, UK defence ministry demos Coanda-effect UAV flights Battery-powered prototypes demonstrate...
Jean-Louis, Excellent desgin! I see the piezo gyro used for yaw control in your photos. But I don't see how you are actually acomplishing yaw. You seem to be...
the current propeller of the gfsuav generates a downward airstream which must be re-directed sideways to get the Coanda effect. Why not use a propeller (a...
Dear All, You will find below a detailled photo of the onboard equipment of the GFS-UAV N-01A such as the piezo gyro to control the anti-torque rudders, the...
Dear All, You will find below the GFS-UAV N01A and N01B specifications under construction and/or testing phase : The main GFS-UAV project page has also been...
Dear All, Another interesting document about the Coanda Effect (in French) about the Coand Effect at : _Ecoulements où la viscosité est négligeable_ ...
Dear All, I recommend you to read this interesting Power Point presentation about the Coanda Effect. _Fluid dynamics : Governing equations, the Coanda effect_...
Dear All, To understand better the Coanda effect model applied to an aircraft design, I recommend you to read this paper : * _Navy successfully simulates...
Dear All, You will find below the engine specifications for the GFS-UAV N01A model. This is a high efficiency LRK brushless motor (outrunner) : Motor diameter...
Dear All, You will find below the technical specifications of my GFS-UAV N01A (the smaller model). Ps: Sorry, I have resent the mail, with a GIF picture,...
Dear All, Thanks for your interest in the GFS-UAV Project. You are Welcome to this group-list. This group is dedicated the GFS UAV a flying saucer which uses...
