 |
Challenged by relative motion aerodynamic or hydrodynamic simulations? Multi-store release from a complex aircraft? Trains passing in a tunnel? Ships with rotating propellers operating near the free-surface?
USAERO is the engineer's choice for these and other transient calculations. USAERO's unique coupling of potential flow and boundary layer methods with a time-stepping procedure for arbitrary motions assures timely and cost effective assessments of unsteady surface pressures and loads.

Trains Passing in a Tunnel

USAERO calculates the transient aerodynamic characteristics of complex configurations in arbitrary motion. It is based on a time-stepping procedure, which allows relative motions of configuration components. As integral potential flow and boundary layer methods are the basis of this CFD software, the aerodynamics solution is only required on the boundary surfaces for each time step and requires only surface meshing.

Furthermore, while components or bodies may involve relative motions, no regridding is required by the solution scheme. Because of these features, USAERO supports practical engineering solutions for such problems as maneuvering aircraft, formation flying, aircraft stores carriage, gust response, rotor/body interactions, and train passing and tunnel entry. Special application modules, FPI and FSP, couple with USAERO to provide, respectively, flight-path integration calculations with six degrees of freedom and ship nonlinear free-surface simulations.
