Litespeed Posted September 23, 2015 Share Posted September 23, 2015 I don't know if anyone noticed but the Greeks have taken the whole budget problem to heart. Instead of the F35 and such they have developed their own and saved billions. As a Nato member this design makes a lot of sense. Running costs are o.1% per hour of other designs and is perfect for low level attack missions dropping olives Welcome the Archon SF1 https://www.youtube.com/watch?v=V8C0T1y9_yw 3 1 2 Link to comment Share on other sites More sharing options...

I wonder what the weight (and other specifications) of this aircraft is? Link to comment Share on other sites More sharing options...
Downunder Posted September 23, 2015 Share Posted September 23, 2015 At the start I thought it was a mock up, a prank but it got faster and faster........and then holy cow it flies!!!!! http://www.aerosports.gr/........ Rotax 2 stroke engine.... What a great job...... Seems to be about 200kg empty and 300kg MTOW...... 1 Link to comment Share on other sites More sharing options...
Keenaviator Posted September 23, 2015 Share Posted September 23, 2015 And it appeared to be well behaved. Nice one. Link to comment Share on other sites More sharing options...
eightyknots Posted September 23, 2015 Share Posted September 23, 2015 The 100 kg difference between empty weight and MTOW would only allow for a relatively light pilot and a little fuel. Link to comment Share on other sites More sharing options...
eightyknots Posted September 23, 2015 Share Posted September 23, 2015 The silhouette of this aircraft looks pretty menacing. I would not fly one recreationally anywhere near the Middle East in case the pilot's intentions are mistaken! 1 Link to comment Share on other sites More sharing options...
Litespeed Posted September 23, 2015 Author Share Posted September 23, 2015 I expect that weight wise it is artificially low to meet the regs for category. Given that it quotes up to 130hp for engine, I expect their is some headroom weight wise available. OR it is for the new greek economy and they expect small underfeed pilots. Either way he deserves big points for making it work Link to comment Share on other sites More sharing options...
Kiwi303 Posted September 23, 2015 Share Posted September 23, 2015 They are short aspect wings, and don't look like much chord length either. Small wings to keep the silhouette close to authentic means to make the stall speed requirements for microlight/ultralight category registration, it would need a low wing loading equating to a low weight. Add another 2 feet on each wing for a 4 foot addition to the span and it would no longer look quite so realistic from underneath. But should make the UK/EU 450Kg MTOW edit. I googled the UK/EU regs. 300Kg MTOW for single seat landplane, 390 for a two seat landplane. I had seen 450Kg tossed around plenty of times, but turns out that is for a two seat. Which this is not. Dual classes like our NZ 544Kg single seat 600Kg two seat. Plus amphibs get more too. Link to comment Share on other sites More sharing options...
Litespeed Posted September 24, 2015 Author Share Posted September 24, 2015 That is a good point about wing area, but we may find this is actually a bit of a special case due to design. Considerable lift would be present from the shape of the body in this particular design. The ducted area should be providing some lift as well, a bit like a box wing planform. The upper and lower surfaces of the duct area act like wings. This is discussed a little on the website. I do not know if the Stall speed is a real world one or from the normal method of calculating by wing area. But for our purposes and rules it could be a great little homebuild. Pity the site has no prices for the kit. As a side: I have used one of the photo's from his site for my picci. No that is not me but cameras crack when taking my photo.

Litespeed Posted September 24, 2015 Author Share Posted September 24, 2015 Well, you look pretty young in that new avatar, Litespeed makes me feel like a spring chicken. Not a grey hair in sight and I bet both his kidneys still work, and his liver. 1 Link to comment Share on other sites More sharing options...
