18th INTERNATIONAL ICING COURSE
Simulation Methods (CbA) for the In-flight Icing
Certification of Aircraft, Rotorcraft and Jet Engines
Tuesday May 26 to Friday May 29, 2020
Come and See Icing Certification-by-Analysis Tools in Practice
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-tocertification, 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.
