Objectives


The overall ambition of STORM is to:

a) Develop and validate advanced simulation tools which will provide a predictive capability on ice accretion and release mechanisms within a propulsive system environment

b) Investigate and validate cost and energy efficient innovative Ice Protection System solutions for future propulsive system architectures

This ambition can be broken down into the following technical objectives:

  • Improve the capability of simulation tools for the prediction of ice accretion with runback phenomena due to glaze ice conditions or activation of the thermal IPS. This will be possible through the development of more realistic models. That improvement will be assessed by experimental validation on representative components
  • Develop a capability to predict droplet re-emission from trailing edges of blades and re-accretion in rear parts that currently does not exist at all. This will be achieved by building and testing components representative of re-emission phenomena in engines, such as water film centrifugated on rotating blades and fixed rows of blades placed in front of each other
  • Improve ice block trajectory models in terms of positioning deviation compared to experimental findings thanks to:
    • A better characterisation of aerodynamics characteristics (lift, drag, moment) of considered ice shapes
    • The use of more realistic, full 3D deterministic numerical approaches that take into account all effects driving ice trajectory, whereas all these effects are not considered so far (such as ice block rotation)

In addition to these technical objectives, STORM will disseminate its innovations, as a part of European Union and National projects (HAIC, AEROMUCO, Clean Sky SGO and SFWA) set up under WEZARD roadmap. WEZARD will coordinate their activities to move all development towards a common action and purpose.
