TOICA contribution to aircraft
architectures
TOICA is improving the complex representation of the thermal behaviour of a whole
aircraft by developing NEW:
Trade-off mechanisms for complex integration of more dissipative systems
Thermal assessments earlier and more reliable to get right first time architectures
Faster and more robust design processes to attain more integrated functions
Capabilities for agile exploration of more complex design spaces

Plateaus
Optimise the overall aircraft
More energy to dissipate in aircraft o More power demand o Deeper integration (confinement) o New electrical architectures
New cooling strategies to assess
o Lower energy dissipated o More efficient energy transfer
New engines & nacelles to integrate o Increase of by-pass ratio o Shorter nacelle o More electrical functions
Engine bleed take-off o Lower bleed off take needed
TYPICAL TRADES IN TOICA
Need of shielding on Pylon ?
Relocate equipment for better
integration (avionic, valve, sensor)?
Pylon width ?
Evaluate operational models
impacts?
Minimise weight under
thermal constraints ?
Amount of heat transfer to
fuel with better control of
flammability risks ?
Minimise needs / Maximise
overall efficiency of
ventilation/cooling systems ?

Collaboration Capabilities
• Creation of distributed dataset
• Use of collaboration standards
Thermal Modeling and Simulation Capabilities
• Management of pyramid of models
• Uncertainty management
• Multi-physics and multi-level coupling
Lessons learned beyond
thermal…
Extent TOICA approach through long term strategy to
• More complex functional/physical architecture descriptions. More value will come in addressing more multi-functional architecture.
• Next life-cycle design steps: detailed design phase, certification
TOICA already shows value on a set of use cases by working on consistent and realistic aircraft descriptions.
During plateaus we explore new processes, roles, capabilities
New skills and roles emerge from the trade-off scenarii
TRL4 criteria drive plateau actors to mature the overall methodology
Project strength: TOICA succeeds in putting Thermal challenges into a common context with OEM’s, Suppliers and Vendors in joined up efforts.
The concept of “integrated project” is key for TOICA.
Better understanding of thermal behaviour in early design phases
• Based on Collaborative Simulation platforms and standardisation (MOSSEC) allowing seamless exchanges in the Extended Enterprise
More robust decision making process enabled by • Earlier thermal assessments in trade-off studies • An overall aircraft thermal behaviour better captured and integrated • Thermal data/metadata populating all exchanges and gates • Multi-disciplinary/Multi-level optimisation of systems
Architects and Designers empowered by new capabilities • Creating opportunities for discovering, identifying and assessing valued
product architectures and designs • Gaining competitive advantage by infusing technologies arising from R&T
projects directly during thermal trade-offs
