Efficient Quiet Integrated Propulsor (EQUIP)

Current icing simulation tools are not fully developed and validated for engines and the associated regulatory environments. Under the EQUIP Technical Challenge, NASA seeks to develop simulation capabilities to estimate the 3D location, extent, and shedding of ice accretion on next-generation integrated propulsors (ducted or un-ducted). The tools will focus on both supercooled water, which affects the fan and front regions of the engine, as well as ice crystal icing, which affects the engine’s core region.  To assess these simulation tools, NASA is also gathering requirements for an engine fan icing test rig which it will look to implement in the future.  Improved icing simulation tools will help reduce risk for market entry of new aircraft propulsor technologies by allowing icing to be addressed earlier in the design cycle.
