New winglet manufacturer excels on Citation X
By John Croft

DATE:10/10/08
SOURCE:Flight International

Winglet Technology says its Cessna Citation X elliptical winglets will be certificated by June 2009 after seven years of testing by Cessna.
The $395,000 retrofit kit, not including installation, will provide a 15kt (28km/h) speed increase at altitude, an additional 545kg (1,200lb) take-off performance at hot and high airports or an increase in range of up to 280km (150nm). Along with a reduced time to climb, the graphite epoxy winglets will generate a reduction in fuel consumption by 4-5% for long-range missions.
Fort Felker, vice-president of engineering for Winglet Technologies, says modifications will be carried out at Cessna service centres, where maintainers will reinforce the four outer bays of the wing to support the additional structure. Unlike Aviation Partners blended winglets, the elliptical design spans the full width of the wingtip and is curved at all points along the structure versus a straight winglet that is connected to the aft portion of the wing and blended into the wing using a radius.
The difference, says Felker, is lower loads on the aft spar of the wing and improved aerodynamic performance. Winglet Technology is also in the running to supply winglets for Beechcraft's Premier II, due for first deliveries in mid-2010.
The company is also developing methods to actively control winglets to decrease the need for structural reinforcements for winglet installations, thereby further increasing fuel economy and performance benefits.

$395,000 for the retrofit. Their website claims it is like a free tank of fuel every 15 fillups. That won't take long to pay for itself if it is true.

Hey Whale, have you heard if XO is going to put them on all our aircraft?

A faster X?! Because .92M really is dragging A$$. Another mod like this and the X will be the only civilian aircraft capable of supercruise.

Cool pix.

As I understand the engineering, MMO will still be .92 but the winglets will allow the aircraft to achieve that speed at altitudes and weights that it currently cannot. The winglets will also improve initial cruise altitude and range.

Is NJA retrofitting theirs?

I'm on the other side of the house so I haven't any idea. Anyone else?

Enough
While they are undoubtedly a good thing and would be nice on all the Xs out there, I have strong doubts that any of the fractionals will be shelling out for them any time soon. At nearly 400K not including installation and down time costs I just don't see it happening for only 4 or 5 percent fuel savings- especially in the uncertain economic times we are now seeing. The most likely way for the fractional fleets to see the winglets is if Cessna decides to whip out a X+ version and only offer it with the winglets.

Now you can fly from service center to service center even more efficiently.
