Topless dancing??

[Griffin]

never saw that. But now it sounds heavy :D

I thought so too but the 15 Sq Meter is 43 kg (93 lb) compared to the Stranger 15 at 48kg.

Also, I know that the flying and landing cables do a lot for absorbing shock and turbulence. This rigid system must surely be a lot rougher in flight?

[DarkHelmet]

Confirmed, Jenya is is working on one out at Petit... He says he is still trying it out ... MmmmMMmmmm

I am still waiting for Jenya to b$%tchslap me for the way I folded my wing when I delivered it to him today

[Smiley]

Wouldn't that be awesome! Never have to stop flying!! :D Actually the wings has struts to support the +\- GGGGGGGG's!!!

[Morph]

With this sort of design I wonder whether a fully symetrical wing is possible? Could make the trike aerobatic?

[AndyCAP]

Dont think so Morph

Trikes are weightshift and rely on the weight being below the wing for stability and Control. When inverted (the only time the symmetrical foil will be advantageous) the weight is above the wing which will be highly unstable and probably uncontrollable

[FAWGie]

The notorius whip stall demonstrates what happens when the undercart gets above the wing too.......

There are two in Knysna at Warren Rosewell's field one a double surface single seater and the other a dual seat version. Both of them are North Wing trikes - very fast and good finishes as with most imports. Both are brand new.

Both are owned by Tom who at 79 is not flying trikes regularly - most probably will sell them off as he has a share in a Cheetah and a new Rans Coyote

Not only does the wing rely on weight shift, but you rely heavily on the pendulum effect of the undercarriage for stability, and even if the wing is more rigid, the undercariage moves independently to allow for weight shift.

The trike can already do many aerobatic manuevres, although they are not designed for it, if executed properly, should not cause a break, but because you do not have rudders and aererons, you will never be able to do a hammer head stall, or a spin.

The wing also has wash-out, which means that the angle of attack at the root is more than at the wing-tips, so flying upside down is not a good idea, as it will become unstable.

Trikes also have quite a bit of dihedral, for stability, anhedral with a heavy undercariage above (as with upside down flight) would not be able to be sustained. ($$)($$)

Hey, FF...
you have been rather quite of late?

All ML wings look the same to me, fine with minor diffs but what is the physical diff between double surface and single? I've seen vids of both, but they look the same? What am I missing? Double sounds like it should be twice as noticable.

[airbornex2001]

Double surface wings have the cross bar enclosed in between the top and bottem wing surfaces, these are faster wings due to less drag. Single surface wings have the crossbar exposed. Single surface wings are great for quick rigging and slow flight. The hangglider aerotow trikes are usually single surface due to the slower speeds they fly. The Northwing picture at the start of this thread is single surface.

[DieselFan]

Thanks for the reply

So I actually flew a dbl surface wing on Wednesday...the guys were comparing the two and I think I heard them say Aquilla2. Can't say I noticed much in terms of dynamics vs, with a whopping 4 hours who can

Pitty you sold your trike to the wrong person , I wanted it , with an Avg speed of 21km/h to work nowadays who needs a car

[Jenya]

Hi guys.
Soon we will be importing new Antares trike with a long-capacity tank and wide tyres it will go with our new topless wing Stratos-15.



We made some simple load tests of Stratos so far and of course test flights. It has been tested for -3G on the ground and +2.5G inflight and flies beautifully accroding to opinion of our test pilot Andy Kaspersen (Petit). We also installed one on a Raptor trike and it is flying in South Africa.



At the moment we busy to make another 4 wings so it will be possible for anybody to come and see it and may be try it out. You can have a look at some pics of the wing and the trike on our website http://www.aerossa.co.za

OK I don't know much about trikes apart from the fact that I am scared of them.
Will this in any way help that the hangers don't have to be so high.
