BOEING 717
performance improvement
Phase A 9 / 15 / 2021
Phase B 11 / 15 / 2022
In development is our Supplemental Type Certificate for Boeing 717 performance improvement. Not merely a cruise performance efficiency program, but a field performance enhancement that will yield added revenues, especially in short field operations or hot and high airports.
A unique but validated way of improving L/D by way of a wing extension, our design requires no added structural beef up as is usually the case with large winglets. Instead, DCA employs a load alleviation device to ensure safety margins to ultimate loads for certification and to maintain limits of validity on life cycle. An aspect ratio improvement of 8.5% and a span increase of over 5% combine for an improvement of over 4% in L/D. This benefit is not just in cruise but from weight off wheels to touchdown.
In addition to the L/D improvement, DCA has also developed a series of aerodynamic clean up elements including fairings, seals, and covers for a total combined drag reduction of over 6%, and corresponding range improvements, as well as significant field performance. This includes some elements from the Super98 acquisition.
