Winglets vs Tip tanks ?
(OP)
Quick question,are large tip tanks on say a larger cargo plane ,in essence serving the same purpose as winglets.Do the large tip tanks create the same aeronautical advantages that purpose built winglets provide.I would say no,as theywould not create a longer "virtual span".This question arises out of a discussion group on the Lockheed Constellation,with some versions having very large tip tanks accomadating as much as 600 gallons or so of fuel.The structure is indeed tip tank like in nature having no real airfoil or camber,simply large tanks,anyone have any thoughts ?

RE: Winglets vs Tip tanks ?
There are multiple approaches to wing tip devices, some of which are better at different speed regimes or even optimized for different portions of the flight e.g. climb V cruise etc..
While 'winglets' or even sharply raked tips are the current fad for transonic air liners and other applications, through history other designs have been used such as simple end plates or 'feather' type appendages.
The longer span approach is one way to look at tip devices, but looking at them as a way to disrupt the tip vortices is another approach where the fuel tank may still achieve something.
Also remember that tip fuel tanks may help with structural loads.
For transonic aircraft they can even be used to tune area rule effects - not really applicable to the Connie!
