Dual Solver Computational Modeling of Ship-Helicopter Dynamic Interface Aeromechanics
Shipboard landings are a fundamental capability of naval aircraft operations and present a unique challenge to helicopter pilots due to the complex aerodynamic interactions between the ship airwake and the helicopter aerodynamics, known as the dynamic interface (DI). As such, detailed analysis and …

AEROMECHANICS OF A DOUBLE ANHEDRAL TIP COMPOSITE ROTOR: EXPERIMENT AND MODELING
… (CAD), Cubit (hexahedral meshing), and X3D (aeromechanics). The 3-D CAD was constructed with guidance from Boeing to ensure the geometry was representative of a modern rotor yet generic enough to be open source for U.S. Gov-industry-academia joint study. The meshing used 27-node solid …

Aerodynamic and Acoustic Modeling for eVTOL Rotor Noise Prediction
… predictions from the Comprehensive Hierarchical Aeromechanics Rotorcraft Model (CHARM), tonal noise calculations using the acoustic solver PSU-WOPWOP, and broadband noise predictions from the UCD-QuietFly framework. Boundary-layer inputs traditionally obtained from the viscous-inviscid solver, …

Helicopter rotor smoothing with a continuous trailing - edge flap
… rotor with the CTEF airfoil on the blade, an aeromechanics (elasticity) analysis is developed in the second part of this dissertation. A 4-bladed baseline helicopter rotor model is developed using a multibody dynamics code Dymore. To validate the Dymore rotor models, flight test data are …

Preliminary design tools in turbomachinery: Non-uniformly spaced blade rows, multistage interaction, unsteady radial waves, and propeller horizontal-axis turbine optimization
<p>Turbomachinery flow fields are inherently unsteady and complex which makes the related CFD analyses computationally intensive. Physically based preliminary design tools are desirable for parametric studies early in the design stage, and to provide deep physical insight and a good starting point …
