Wing modification specialist confirms fuel and emissions can be reduced by up to 4 percent on older 737s
AeroTech's wing flap modification
Fri 19 Jun 2009 – Reno, Nevada-based AeroTech Services says it is seeing positive performance improvement results on the first Boeing 737-400 aircraft utilizing the company’s wing modification. AeroTech says the modification reduces fuel consumption and greenhouse gas emissions by up to 4 percent on the Boeing Classics (-200 to -500 models), which has been verified in FAA flight tests. The simple modification increases the aircraft’s wing area and camber, and lengthens the wing chord, resulting in an increased lift-to-drag ratio, effectively reducing fuel burn and emissions during climb and cruise periods.
“While the current performance improvement trend for this particular European operator is certainly reasonable, we will probably make some minor adjustments to optimize the overall benefits even more,” said James Nettle, Director, AeroTech Services. “It appears the return on investment, at today’s fuel prices, will be about 18 months.”
Airlines currently using the AeroTech patented modification include Brussels Airlines, Swiftair, MNG Airlines, Shenzhen Donghai Airlines, and Ukraine International Airlines. GECAS leases several B737 Classics with the AeroTech modification on them.
