Expected Impacts

SARAH in general will realise strong impacts on three different levels:


As regards aircrafts, the following positive technical impacts are expected:

  • It will be possible to identify the structural requirements associated to a safe ditching process in a much earlier design phase.
  • The project will deliver efficient simulation-based strategies for a goal-oriented optimisation and increase of handling- and approach-condition windows that secures a safe ditch 
  • The project will provide a rational (simulation-based) method to assess the performance of future unconventional design concepts, not accessible by existing empirical approaches
  • The project offers will introduce a holistic design method that is able to address vehicle and ambient aspects (e.g. seaway, ground effects) in parallel.
  • Using the simulation environment will provide an improved understanding of physical phenomena, which in turn enables improved design of future A/C to both improve safety and possibly reduce weight by more accurate, less conservative design loads


In the frame of helicopters several impacts are foreseen:

  • It would have positive impacts on the security of the passengers and crews of helicopters (H/C) thanks to the optimization of the performances of the systems linked to ditching. Consequently it would have positive effects on the global H/C performance.
  • The synergy created by the cooperation between skilled entities (tests facilities, numerical developers and manufacturers) is an open gate to easier further cooperation implying a growth of activities if the results of the project are positive or promising for other exploration of technologies.
  • The project will have positive impacts on the security of the passengers and crews of helicopters (H/C) thanks to the optimization of the ditching performances based upon rational tools.
  • The tools developed during the project offer the opportunity to analyse local effects associated to water impact and to investigate optimized configurations. It is expected, that the integration of innovative systems can be performed in much smaller time scales and at significantly reduced costs. Examples refer to new shapes of floats or fuselages, different kind of interfaces between floats and fuselage or even shock absorbers.

Aircraft and Helicopter design processes

Local impacts on the Aircraft and Helicopter design processes could be measured in terms of the time to solution requirements and the predictive accuracy of developed simulation tools. From the activity point of view all the answers to remaining challenges (overall simulation, local loads determination, global behaviour of floats, …) will allow the manufacturers of A/C and H/C and the specialized supplier of safety equipment to focus on innovative ways to reduce risks (shock absorbers, handling assistance for ditching events, etc.). Hence to open new fields of competence needs will create activities and motivate companies to growth. Apart from that the contributing research institutes will be able to publish results and improve their visibility, both national and international. Especially the use of high-fidelity testing results and the development and application of simulation tools to industrial processes increases the quality of the research institutes, gives opportunities for research to scientists and students and increases the competitiveness of the European research community.

This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 724139.
