For an aircraft, rotorcraft or jet engine to obtain a type design 
certification, it must be demonstrated that it can sustain safe flight
into known or inadvertent icing conditions. The icing certification 
process involves CFD (Computational Fluid Dynamics) analyses,
wind and icing tunnel testing (EFD: Experimental Fluid Dynamics), all 
considered “simulation”, and final demonstration of
compliance through Flight Testing in Natural Icing (FFD: Flight Fluid 
Dynamics).
Modern 3D CFD-Icing methods such as FENSAP-ICE, working as a 
direct extension of CFD-Aero technologies, have become an
indispensable, if not a primary tool, in the certification process. They 
are rapidly replacing 2D and 2.5D methods (airfoils don’t fly;
aircraft do). They enable analyzing the aircraft (fuselage, wing, 
engines, nacelles, cockpit windows, sensors, probes, etc.) as a system
and not as an assemblage of isolated components. Such an integrated 
CFD-EFD-FFD provides a cost-effective aid-to-design-and-to 
certification, when made part of a well-structured compliance plan. 
CbA (Certification-by-Analysis) being a current “hot” subject; this
course puts it into real practice, providing efficient tools and showing 
examples of actual use.
The course will show how modern 3D icing codes are based on highly 
validated physical models (Scientific VVV) as opposed to
simply calibration against icing tunnels. The course will also show how 
Reduced Order Models can make fully-3D calculations
inexpensive and enable identification of aerodynamic and 
thermodynamic critical points in an automated structured way and not 
a heuristic one. By inclusion of icing requirements at the aerodynamic 
design stage, a more comprehensive exploration of the combined 
aerodynamics/icing envelopes, optimized ice protection system design, 
and focused/reduced wind tunnels, icing tunnels
and flight tests. The end result is a faster design, faster testing, faster 
natural icing campaign and a safer product that is easier to
certificate.
This course is structured to be of equal interest to aerodynamicists, 
icing, environmental systems and flight simulation engineers,
regulators and Designated Engineering Representatives. Detailed 
knowledge of CFD is not necessary.
The lectures cover the major aspects of in-flight icing simulation, ice 
protection systems, handling quality issues. The instructors
bring an amalgam of knowledge, as scientists who have produced 
codes in current use and engineers with certification experience,
along with cost-effective simulation methods widely used 
internationally for certification of aircraft for flight into known icing.
