Wake vortex minimization and remedial measures to be taken at the vortex generating aircraft were investigated. Boeing 747, DC 10 and L 1011 aircraft were equiped with spoilers, winglets, ogee tips or splines, and flight tests, wind tunnel and water channel tests were performed. Best results are obtained with spoilers. It is concluded that the additional equipment gives rise to higher engine power delivery at ground approach/take off hence higher noise level and increased fuel consumption.
