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 ?

TOICA develops the concept of collaborative Thermal Architecture Platform

Integrate new capabilities in

trade-off processes

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
