Who will rid me of this turbulent nostril!

Any totally crazy 'first adopter' tried one of these schnozzle shredding gizmos?

Only 100 odd euros from MV! Will they put Tobin out of business...?

Clear prop!!

It says:-

"A new twist on an old idea.

Pilots of the old open cockpit planes knew all too well that being tucked in behind a propeller saved them from the winds forces. Why not try that idea on a BMW...after all, BMW did start as an airplane engine manufacturer.

The force of the wind, sends the propeller in motion. The wind turbulances are then sent elsewhere. As with planes, once the propeller is in motion (starting at about 30 km/hr) it is no longer visible."

(That last bit sounds like an invitation to always wear your blood group dog tags....)

The wash behind the propeller is more severe then the wind itself, because the propeller is driving the plane forward (a fact that the seller seems to have forgotten................

theres so many reasons this is silly, on a plane the prop is at the very front, and is designed in such a way that it sucks air, secondly the wind generated behind the prop is enveloped, similar to that we get on a bike with pillion, third, the airplane prop is alot bigger and heavier, and spinning faster.

who came up with this? silly people


(got 2 on order)

actually, it is in fact... semi.... plausible. A slowly turning prop with a fine pitch will in fact act as a brake on an aeroplane, and feasibly... (with alot of imagination)... a wind deflector as the airflow on the blades will force the air along length of the blades as well as around them... therefore creating a sort of "bubble" of slower moving air...

I fly quite alot and use the prop to slow the plane in descents and aerobatic manouvres, by using a variety of different pitches its possible to limit the speed of descents. The propellor is more efficient as a brake if it is spinning slowly than if it is stopped.

Even so, it looks ****! What are we doing running our own wind turbine system and plugging our bikes into the national grid!

Here you go... works for Biggles ...

Do they do them in c/fibre???

 

[vilguy]

give me 100 quid and ill knock you up one including a little motor to cool you on those hot summer days... the ultimate beemer farkle im sure!

stick a couple of wires on the thing and charge your mobile on the go...
