The R-WAKE Project

Wake Vortex simulation and analysis to enhance en-route separation management in Europe.

As they pass through the air, aircrafts generate strong rotating air turbulence with vortices in the wingtips, which can last for several minutes and therefore can be encountered at considerable distances from the generating aircrafts, until their circulation strength decays and the turbulence disappears. These wake vortex turbulences can be hazardous to other aircrafts if encountered too near and in a bad combination of several factors, being a possible cause of discomfort, incidents, or even accidents. The main protection mechanism to avoid that hazard is to maintain a minima separation to the generating aircrafts that takes into account the wake vortex hazards.

R-WAKE Solution

The project faced a complex development relying on two full iterations, one per year, of the three closely-coupled project work areas, that is: [1] the target concept research scoping and study approach, i.e. defining the target-concept to be assessed, its study scenarios, and the requirements for the safety study terms and the simulation system, [2] the research system development, i.e., the integrated simulation toolset and methodology, and [3] the research realization, i.e., execution of the simulations, data analysis, concept development, safety & robustness analysis, and results assessment.

Expected Impact

The R-WAKE project has clearly identified and preliminary quantified with enough level of confidence the need and opportunity in the ATM system for enhancing the current separation minima schemes provisioned in en-route operations taking into account the generated knowledge on Wake Vortex hazard assessment applying a high-fidelity simulation based approach. The project tangible outcomes include ...

R-WAKE consortium includes two research universities: UPC and TUBS, and four SMEs: GTD, DBLU, A-SYST and M3. The partners come from five European countries.
