AvAero FuelMizer

AvAero's FuelMizer is the only wing modification for the B737 -200, -300, -400, & -500 series designed to improve lift and aerodynamic performance without costly structural modifications.

FuelMizer enhances the aerodynamic efficiency of the wing by increasing the aircraft's lift-to-drag ratio. By reducing induced drag, a byproduct of lift, the FuelMizer modification is able to deliver typical fuel savings of 4% plus.

How it works...

The aft segments of the trailing edge flaps are relocated aft and below their standard locations when the flaps are retracted. These changes result in increased wing area, increased airfoil camber, and a lengthened wing chord.

The patented FuelMizer modification allows the flaps to resume their normal positions during flap deployment and are not limited in travel or operation.

FuelMizer increases lift while reducing drag without costly structural modifications.

FuelMizer improves aerodynamic efficiency.

  • Increases the wings' lifting capability
  • Reduces inherent induced drag on both the wings and horizontal stabilizer

The Results...

  • Decreased time to climb
  • Reduced power necessary to maintain a given altitude and airspeed
  • Reduced take-off noise
  • Higher initial cruise altitude
  • Increased range
  • Lower NOx

The bottom line...
FuelMizer saves you money.

  • Reduced fuel consumption for a given flight
  • No change to operational or flight procedures
  • And more importantly...108,000 gallons saved per aircraft per year
