Descripción del proyecto
Un sistema para bajar el volumen a los aviones
Los aviones resultan ruidosos durante las operaciones de despegue, sobrevuelo y aterrizaje. El ruido producido se debe principalmente a la radiación trasera y la admisión. Se han utilizado tecnologías pasivas para disminuir el ruido, pero no alcanzan el nivel de reducción deseado. Resulta esencial mejorar las nuevas tecnologías, tales como la innovadora tecnología de estátor. El proyecto financiado con fondos europeos InnoSTAT se propone alcanzar el nivel de preparación técnica tres con un mínimo de tres conceptos de OGV a escala completa. El proyecto incluye una metodología sistemática para las tecnologías de OGV en cuestión que se emplea por primera vez y tiene por objetivo mejorar los motores de los aviones.
Objetivo
The noise reduction measures for engine related noise from the intake, but also for rearward radiation is highly targeted during the last 15 to 20 years. Most effort has been made in passive technologies for intake liner concepts, but also for the low noise design of fan and stator blades. From all the current available technologies a noise reduction related to engine sources by 6 dB can be expected, which is a big achievement, but still does not suffice to reach the goals. Thus, a further refinement of possible technologies has to be re-opened, like in the case of innovative stator technology. The proposed work of InnoSTAT consists in a systematic procedure, which has not been performed yet for considered OGV technologies. InnoSTAT will be the first project where the activities are focused on the above process with the only goal of bringing at least 3 OGV concepts to demonstrator level at TRL3 on full scale. This has not been achieved yet in any other programme for one OGV concept. The project’s objectives are
• to define 5 novel low noise stator concept designs, to develop and test them on prototype level TRL2 to TRL3,
• to select and develop 3 novel stator concepts for further advanced design, characterisation and full 3D stator stage large-scale testing of 2 OGV stages to TRL4,
• to define, design and manufacture 1 demonstrator OGV at TRL3 on full-scale.
The project’s goal will be achieved in 3 major steps by 1) testing and improving the technologies 5 concepts on small-scale prototype level, 2) down selection of 3 technologies for further test of two of them on large-scale, each as a fully equipped stator stage, and 3) finally 1 selected concept demonstrator to be manufactured and perform an integration study regarding engine environment.
This 51-months project with its ambitious goals will request 2,788 k€ in total. Its contribution to the noise reduction on ultra-advanced long-range and ultra-advanced short-/medium-range will be significant.
