ATI is an industry leader in producing sub-scale composite rotor-blades for performance or dynamic wind tunnel testing. Design of sub-scale composite blades often requires the use of significantly lighter/thinner materials and, as a result, can be even more challenging than developing full-scale composite blades. Previous sub-scale development programs have included all types of complex airfoil/blade geometries, active/passive flight control devices, and on-board instrumentation.
While many of our sub-scale blade designs are composite,ATI also has experience fabricating all-metal (aluminum, steel) blades. Design and fabrication of sub-scale metal blades present unique challenges and must be carefully developed/processed to ensure dimensional stability and resulting inertial blade characteristics.
ATI has also produced sub-scale propeller blades (both aviation and marine applications), turbine blades, and wind-tunnel fan blades.
ATI has the knowledge and experience to meet the challenges of producing blades that perform as intended.
