The unsteady flowfield of a Bell-Agusta 609 rotor is numerically investigated with an unsteady Reynolds-averaged Navier-Stokes flow solver based on unstructured grid topology. The geometry considered is a three-bladed rotor that is undergoing a highe

Two new mechanisms for downstream ice growth (i.e., downstream of the primary ice shape) in aircraft icing scenarios were investigated. The first mechanism is local variation of relative humidity with its potential for water deposition due to supersa

An unstructured hybrid approach is developed aimed at computing viscous flows around helicopter rotors in hover and forward flight. A single rotor blade is resolved through the Navier-Stokes solution with the consideration of the blade vortex interac

Momentum blade element methods, which have historically been used to predict rotor blade thrust, underpredict the power that is required for highly twisted rotors at high thrust levels. During a test of the V-22 tilt rotor blade conducted at the NASA

An airfoil design procedure is described that was incorporated into an existing 2-D Navier-Stokes airfoil analysis method. The resulting design method, an iterative procedure based on a residual-correction algorithm, permits the automated design of a

Even though aircraft icing has been an active area of research for many years due to its public safety ramifications, there are still gaps in the knowledge base, such as in the ice accretion process. Ice prediction codes have been developed and gener
