[QUOTE="digitalmouse, post: 57392, member: 11891"] Ha! You made me shoot cola out my nose! I've flown in 747s, 777s, and 787s (not the X models, mind you) - they can have upturned winglets too. Google is your friend! :-) Very little to do with airport size - they make the runways extra wide for a reason ya know, and when parked there is generally a good minimum of 3-4 meter gap between parked planes even for the big boys. The airport just staggers their placement if the gates are too close, or busses out passengers to aircraft waiting on the taxiways/tarmac. The main points for winglets or sharklets is for noise, more fuel efficiency, and reduce that annoying and dangerous 'vortex drag' that makes takeoffs for following aircraft a scary adventure for us small-engine pilots. On a Spark, as mentioned earlier, the propwash is blocked by some of the drone's body so winglets will have a minimal effect on efficiency. While the general aerodynamics appear to the the same for creating lift, an aircraft wing and a rotorblade have significant differences in how that lift leaves the lifting surface. You generally don't see winglets on helicopters (or jet engine fans, for that matter), but you do see raked-back rotor-tips, which a Spark [I]might[/I] be able to take advantage of. The props wouldn't need to be any bigger/longer, just have the last half-centimeter or so re-designed. [/QUOTE]
