Rotary-Wing Aerodynamics

The rotary-wing aerodynamics program at the NRC Institute for Aerospace Research (NRC Aerospace) carries out studies in unsteady rotary-wing aerodynamics, integrated rotary-wing modeling and simulation, flight mechanics, flow physics, flow-induced noise, and the physics of ice accretion as well as its aerodynamic impact.

These studies are carried out to support the R&D efforts of Canadian aerospace manufacturers and develop a better understanding of rotary-wing flight vehicle operation in adverse weather and extreme flight conditions. Studies are also conducted to help Canada's National Defence assess the aerodynamic performance of its rotary-wing vehicles and provide service-life assessment as well as rotary-wing flight simulations.

NRC Aerospace integrated modeling and simulation research capabilities include:

• CFD modeling and simulation of flow surrounding rotary-wing flight vehicles
• experimental rotorcraft aerodynamics (supported by NRC wind tunnel facilities)
• unique experimental and numerical modeling capabilities for icing problems, and
• high-fidelity wind tunnel simulation of the helicopter/ship dynamic interface.
