Rotorcraft | CD-adapco
Top-of-the-range analyses tools for the design and optimization of modern rotorcraft
Perhaps one of the most complex and difficult to understand engineering principles that humans study currently is the physics behind Rotorcraft.
  • The trimmed hexahedral surface mesh and velocity vectors showing the ground effect and the complex flow field around the helicopter blades are displayed in this STAR-CCM+ simulation of an Apache attack helicopter.
  • With STAR-CCM+, engineers are able to perform the most detailed and accurate calculations ever in a fraction of the time, creating much safer, more reliable and better performing rotorcraft. Shown here is a STAR-CCM+ simulation of Oryx helicopter displaying streamlines originating at blade tips.
  • Isosurface of Q-criterion colored by vorticity showing rotor wake from a ROBIN body. This simulation was generated using an overset mesh.

While humans have used helicopters and the like for decades, difficulty analyzing the physics behind the lift and the complex interactions have wasted billions of dollars in design mishaps.

However, with CD-adapco’s STAR-CCM+, engineers are able to perform the most detailed and accurate calculations ever in a fraction of the time, creating much safer, more reliable and better performing Rotorcraft.

In particular, the modeling of a helicopter's propellar blades may be done with Overset Meshing, which allows the propellar to rotate within the simulation's reference frame and much more accurately model the airflow, lift and drag of the craft.
