BOEING 717
performance improvement
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.
Initial phase of performance improvement package was validated in cooperation with a major operator. Results were shown to meet an improvement of 2.5% as predicted.
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. 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 exhaust fairings, for a total combined drag reduction of over 6%, and corresponding range improvements, as well as significant field performance.
