  • Drag reduction for gas turbine engine components
    Patent number: 6666646
    Abstract: Gas turbine engine components which are supplied with longitudinal ribs on the areas that are in contact with a gas flow, whereby the riblets have a length of at least 5 mm, a height of at least 0.02 mm and a width of at least 0.01 mm. Those riblets are applied using the High Velocity Oxyfuel Process (HVOF). Using this technique material in the form of a powder is applied at high velocity onto the substrate of the gas turbine engine components with the riblets created preferably by positioning a mask in front of the subject part. If necessary, prior to the application of the HVOF coating, a bondcoat can be applied on the subject parts.
