Opis projektu
Tłumienie hałasu samolotów
Samoloty wydają głośne dźwięki podczas startów, przelotów i lądowań. Hałas generowany jest głównie przez wloty oraz wyloty silników. W celu jego ograniczenia stosowano dotychczas technologie pasywne, ale nie przyniosły one pożądanego poziomu redukcji hałasu. W związku z tym niezbędne jest doskonalenie nowych technologii, takich jak innowacyjna technologia stojana. Finansowany ze środków UE projekt InnoSTAT ma na celu wprowadzenie co najmniej trzech koncepcji OGV na 3. poziom gotowości technologicznej na pełną skalę. Projekt obejmuje systematyczną metodologię dla rozważanych technologii OGV, która jest opracowywana po raz pierwszy i ma na celu ulepszenie silników lotniczych.
Cel
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.
