Descripción del proyecto
Optimización aerodinámica de la admisión de aire en aeronaves
El proyecto TRINIDAT, financiado con fondos europeos, abordará la aerodinámica de una geometría de admisión previa y la mejora del rendimiento de dicha admisión mediante el uso de herramientas de optimización basadas en dinámica de fluidos computacional. Su objetivo es generar geometrías de admisión de alto rendimiento remodeladas que se empleen en la nueva generación de sistemas de motor basculante de uso civil. Un convertiplano puede funcionar como un helicóptero o bascular sus motores y volar como un avión de ala fija. El proyecto mejorará la estabilidad del flujo y la uniformidad de los sistemas de admisión de aire de los motores para cumplir con los requisitos de los fabricantes de motores. Además de optimizar el rendimiento aerodinámico de la admisión, el proyecto identificará situaciones de engelamiento y deposición de nieve a tener en cuenta de cara a su certificación.
Objetivo
The TRINIDAT project adresses the aerodynamic characterization of an already available intake geometry (as supplied by ITD) and optimization of the intake performance by using CFD based optimization tools leading to redesigned high performance intake shapes to be implemented on the Next Generation Civil Tilt Rotor (NGCTR) configuration. A purpose of the optimization is to improve the flow steadiness and uniformity at the Air Intake Plane of the engines such as to comply with the requirements put forward by the engine manufacturer. The initial characterization and optimization will rely on dedicated CFD studies, the final validation will be made with full size model tests in DNW-LLF 6x6 wind tunnel, allowing reliable testing at full scale Mach and Reynolds conditions. For efficient testing of basic and optimized left hand and right hand intake geometries in airplane, helicopter and intermediate Extreme Short Take-Off and Landing mode, a modular wind tunnel model equipped with a remotely controlled tilting forward nacelle part will be designed and manufactured. A remotely controlled highly instrumented rotatable rake will be installed in the model to enable detailed and efficient measurement of the flow at the engine air intake plane. Apart from the aerodynamic optimization of the intakes, the project will also identify icing and snow conditions to be considered for certification and will subsequently analyse the ice and snow effects on the nacelle inlets and ducts to provide early input for anti icing measures that might be needed for NGCTR.
The partners of the consortium, gathering renowned Research Centres (NLR, DNW), 2 Industrials (Deharde, ALTRAN), 1 SME (ADSE) and 1 University (UT), will use their complementary expertise and facilities to provide an optimized inlet geometry for NGCTR, based on CFD and wind tunnel analysis, with high potential for certification in snow/icing conditions.
The TRINIDAT project will last 39 months for a total budget of 3,346,397€.
