Work Plan

Plateaus and Project Milestones

TOICA builds on and exploits the Behavioural Digital Aircraft (BDA) as one of the main results of the CRESCENDO project (2009-2012).  The BDA allows remote teams (architects, experts and suppliers) to work collaboratively and share data.  In TOICA, the remote teams worked together to perform trade-offs to converge to the main promising thermal aircraft concepts in a series of eight evolving plateaus which correspond to the project milestones. 

Plateau way of working


Each plateau is a virtual and physical coming together of architects, experts and suppliers in the extended enterprise in programme-like conditions to:

  • Test and improve the trade-off processes that were increasingly instrumented by the capabilities enablers.
  • Validate the definition, selection and evaluation of thermally optimised aircraft configurations.

A gap analysis following each plateau allowed the identification of considerations for preparing the next plateau iteration.  Through these plateaus, the Use Cases showed how to manage studies in the collaborative environment as a part of the trade-off process and the aircraft alternative selection.  The trade-offs performed and resulting alternative architectures were analysed for benefits. 


Work Breakdown Structure

SP1 - Collaborative Design Capabilities

  • 11Super integration
  • 12Architect cockpit
  • 13Behavioural Digital Aircraft platforms

SP1 develops the new approaches enabling the aircraft architects to assess new concepts and to investigate new radical potential changes for new overall integrated concept of aircraft.

SP2 - Modelling & Simulation

  • 21Flexible models
  • 22Model pyramid
  • 23Multi-physics coupling
  • 24Optimisation
  • 25Robust analysis

SP2 innovates thermal modelling and simulation methods to enable experts and architects to generate collaboratively the pyramid of functional and physical models representative of the aircraft thermal behaviour and to answer to the trade-off requirements and constraints.

SP3 - Thermal Studies

  • 31Thermal aircraft
  • 32Equipment integration
  • 33Cooling technologies
  • 34Heat sinks
  • 35Thermal management
  • 36Powerplant integration

SP3 investigates new methods and collaborative processes to simulate innovative product technology propositions for future aircraft.  Through six dedicated Use Cases, innovative integrated concept design scenarios are demonstrated, which secure integrated thermal behaviour and competitive overall multi-discipline performance and behaviour.

SP4 - Plateaus & Trade-offs

  • 41Baseline aircraft dataset
  • 42Thermal trade-offs
  • 43Super-integration implementation
  • 44Value assessment

SP4 represents the full aircraft level of integration and delivers the main evidence to demonstrate achievement of the high-level objectives and show benefits to the end users in ‘programme-like’ working environments (plateaus) as the capabilities mature.

SP5 - Project Management

SP5 provides the strategic, technical and contractual management to the Consortium including dissemination and exploitation.
