@marcio50 How much does the airship cost to be done?

[marcio50]

@FVCup Please contact me by email: skymidia@terra.com.br

and I'll send you all the info and costs.

@marcio50 Do you have a video in you Tube on this ?

[metacosmos]

@marcio50 No if you put at the end of the mast that support the sail ( in one of the sides of the blimp) an adittional small helium blimp to stand the weight of the mast. Of course, in hard winds the blimp will follow the wind but , as it happens with sailing at sea, the sail and the game with the rudder will allow some control of the direction, because the sail in the blimp affects only one side of the blimp .

@metacosmos

But, in a RC blimp it would not work. A sail only will make harder for the blimp to find its desired direction, and also, we would need a mast or something to position the sail in different wind situations, making the blimp too heavy.

@marcio50

We do use a "sail" on a anchored blimp. A triangular sail is attached to the "equator" of the ballon, hanging upside down. As the wind blows and forces the sphere DOWN, also hits the sail and forces it UP, making the entire gadget achieve the equilibrium. Theoreticaly, the harder the wind blows, the higher is the pressure UP. Works like a charm and it amazes people with "normal" spherical blimps.

@metacosmos@metacosmos Your logic is tricking me... Am I missing something???

A sail in a boat only works because the rudder is inside the water and the resultant force between wind direction, rudder direction and sail direction determines the final direction of the craft.

On a blimp, BOTH (the sail and the rudder) would be on the air. As the wind direction enters the equation, the resultant would be always favoring towards wind direction.

@marcio50 i meant rudder for bladder , sorry.

@marcio50 A sail in one side of the blimp, to negociate against or for the wind, as the boats do, it is possible because the sail is only in one side of the blimp and you can use the bladder to negociate with the wind and the thrust that pushes the blimp from the side of the sail. I know that a ballon cannot deal with the wind because the ballon is carried by the wind, but by a sail in one side you can negociate somewhat with that wind, and by the bladder.
