Toolsets and scenarios

Toolsets and scenarios

June 20, 2018

This set of activities covers two objectives.

The first objective is to develop a tool for noise specialists to predict the noise and annoyance impact of chosen flight scenarios, including new architectures and technologies, and an additional user-friendly tool for non-specialists to enhance their decision capability whilst heightening their proficiency. The second tool includes input data for a Virtual Reality device for Communication purposes.

The second objective is to guide the elaboration of the European Aviation Noise Research Roadmap, by evaluating scenarios with current and advanced 2035/2050 aircraft architectures with regard to their impact on airport noise annoyance.

As part of the two Toolsets a Noise Prediction Tool will calculate acoustic footprints of single aircraft and whole fleets on an airport. One will be able to modify trajectories, fleet composition, aircraft types and so on.

Toolset developed within ANIMA will help assessing the annoyance due to aircraft noise

More than on noise, ANIMA focuses
on annoyance and impact on human beings

For residents to live a total immersion in 2035/2050 aircraft noise, a Virtual Reality tool will be fed with scenarios including new aircraft architectures.

Virtual Resident, the tool that will enable specialists and non-specialists to evaluate annoyance of airport scenarios, can be compared to complaints maps in order to evaluate their grounds.

Assessing the impact of future aircraft

ANIMA will investigate on the potential noise impact of highly innovative configurations through its link with the Project ARTEM (Aircraft Noise Reduction Technologies and Related Environmental Impact, no. 769350). The operational scenarios will be projected to 2050 using the most advanced techniques of simulation and metamodeling coupled with state-of-the-art aeroacoustic simulations, in order to improve and extend the existing simulation tools. Two Blended-Wing-Body configurations will be analyzed: the REBEL (REgional Bwb ELectric-propelled), carrying 100 passengers on a range of 900 nm, and the BOLT (Bwb Optimized with Low-noise Technologies), long-haul concepts sized for a 400 passengers payload. The REBEL will be eventually equipped with a hybrid gas/electric distributed propulsion.

BOLT & REBEL configuration are respectively long-haul and regional aircraft prototypes that are being explored by the ARTEM sister-project. Their noise impact in current or forthcoming scenarios is assessed by ANIMA

The figure above depicts the initial layout of the two aircraft, both equipped with generic UHBR engines mounted on pylons on the top of the centre body. The two configurations are aerodynamically assessed, but not yet optimized.
