Objectives and scope

The R3ASC‘23 conference will address the latest developments in aerospace actuation since 2018, when more than a hundred twenty worldwide industrialists, specialists and scientists attended the eighth R3ASC conference.

One cannot deny that the early 2020s' have initiated major changes of the clients' needs, which are sometimes poorly compatible: aviation bashing, reduced impact on environment, cheaper access to space, new air mobility, internet of things, long-range single-aisle commercial aircrafts, etc. This calls for innovative solutions at all aircraft, systems and operation levels, which are mainly driven by ecological and/or economical considerations. The new comers, especially in the field of more/all electrical solutions, combine with the restructuration of historical companies into large industrial groups to offer new solutions and to change the market rules.

    More electric actuation has now started to enter into service and provides accumulated feedback on real usage. The collected data is exploited for sizing optimization and increases both confidence and acceptance. Interaction between physical domains is much better addressed through more integrated design processes, tools and software. New manufacturing means are becoming matured into validated, mastered, stable and profitable processes. All combined enable new aerodynamics designs to be implemented and increase the attractiveness of electric actuation for wider domains of application. These advances also benefit to the conventional hydraulically-supplied actuation that still shows potential margins of progress. Last but not least, more electrical actuation not only benefits from advances in electronics and electromagnetics but also generates a high demand for advanced mechanics, including lubrication, heat transfer, dynamics, load balancing and compact power management functions.

   In order to offer the delegates the widest view on recent advances in actuation systems and components, authors are invited to submit scientific and technical communications dealing with:
   - application to any type of aircraft, including  new air mobilities
   - flight controls, landing gears, engines, and other utilities
   - power generation and distribution, power management
   - hydraulically/electrically/hybrid powered actuation: PbW, HSA, EMA, EHA,…
   - signal transmission and control: FbW, FbL, FblW, FbWL, POD, PLC
   - new architectures for signal/power transmission and transformation
   - multidisciplinary/multidomain/multiscale optimization and design exploration
   - reliability, safety, health and usage monitoring
   - mutualization, modularization, standardization
   - energy saving, environment-friendly design and operation, deconstruction
   - components: direct drive valves, magnetic gears, SiC electronics, etc.
   - ground and flight tests, verification and validation, certification
   - simulation, virtual prototyping, virtual test-benches
   - integration, operation, maintenance, service withdrawal
