Abstract

A computational fluid dynamics code was used to predict drag increments for three proposed commercial aircraft fuselage nose configurations. The CFD results showed that a significant drag reduction could be achieved by eliminating a windshield wiper recess. The predicted drag reduction was of sufficient magnitude to warrant a flight test by Douglas Aircraft Company on an MD-11 airplane. The flight tests confirmed test results that drag reduction was possible.
