World-Class CFD for Aerospace Aerodynamics applications

For over 30 years, ICON Aerospace Aerodynamics CFD has been a trusted, proven option in the aerospace industry. Some of the world’s largest Aeronautical manufacturers and governmental space organisations have already discovered the huge difference ICON can make. With no requirement to be locked into expensive, long-term contracts and significant cost savings compared to many of the big conglomerates, it’s a good time to be talking to ICON.

The big difference is also that we are engineers first, not just expert coders with exceptional software. ICON engineers are fully integrated into the working environment of businesses through on-site support activities. This ensures that a broad knowledge of the technical objective of the analyses is also supported by experience of how new designs will be integrated within the aircraft development process as a whole. Not every CFD software provider is willing or able to do this.

The exceptional design, optimisation and evaluation capabilities ICON CFD options provide will help you deliver measurable improvements in aerospace aerodynamic performance. This includes the whole spectrum of factors including airframe, wing and blade design, aerofoils, propulsion system, environmental effects, landing gear, etc. Put simply though, the ability to reduce fuel consumption, reduce flight time, increase payloads, increase control, etc is good news from environmental, operational and financial perspectives.

Key features of ICON Aerospace Aerodynamics CFD

  • Aerodynamics force coefficients and centre of balance
