In-flight icing is a safety-critical aspect of aircraft design, yet it is a highly complex physical phenomenon that is extremely difficult to replicate using expensive physical tests. Recent regulatory changes and industry focus on the particular hazards presented by high altitude ice crystals and supercooled large droplets (SLD) have further challenged the design process and the time to market for new aircraft and technology.

FENSAP-ICE provides leading three-dimensional, state-of- the-art, design and aid-to- certification simulation software to provide enhanced aerodynamic and in-flight icing protection solutions in a cost-effective manner.

Capabilities of ANSYS FENSAP

FENSAP-ICE 3D CFD simulation system for in-flight icing improves safety and speeds certification of aircraft, helicopters, jet engines, UAVs, instruments and probes.

Calculate the shapes and roughness distributions of glaze, rime or mixed-type ice accretion on aircraft surfaces ranging from wings to air data probes.

FENSAP-ICE models supercooled large droplets and irregularly shaped ice crystals in compliance with the requirements of icing certification envelopes in Appendix O and Appendix D.

Assess the performance of bleed-air and electro-thermal IPS to ensure protection against adverse in-flight icing conditions.

Assess the adverse effects of ice accretion on aircraft surfaces, losses in lift-to- drag ratios, increased blockage of screens and engine passages, and more.

FENSAP-ICE predicts ice accretion due to droplets and ice crystal ingestion in the gas path of turbofan engine compressors.
