Overview
ISO/IEC TR 22560:2017 - Information technology - Sensor networks - Guidelines for design in the aeronautics industry: Active Air‑flow Control (AFC) - provides a technical report on designing AFC systems for commercial aircraft using dense deployments of wired and wireless sensor and actuator networks. The report covers architecture design, module definitions, objectives, scalability analysis, system‑level simulation, and networking/implementation issues using standardized interfaces and service‑oriented middleware.
Key topics and technical requirements
- Architecture & modular design
- High‑level AFC system architectures (layered models, the “bubble” concept and mapping to ISO/IEC reference models).
- Hybrid dense wired–wireless WSAN (wireless sensor and actuator networks) design and module definitions.
- Sensing and actuation
- Micro‑sensors and actuators arrays (patch design), synchronization, high‑rate measurements and data compression needs.
- Requirements for boundary‑layer (BL) detection, space–time resolution and effective flow‑control actuation.
- Networking & protocols
- Communications requirements: interference management, wireless range/connectivity, full‑duplex and relaying considerations.
- Internetworking, protocol translation and integration with on‑board avionics (compatibility with ARINC 664 and avionics networks).
- Quality, safety & resilience
- Re/auto/self‑configuration, troubleshooting, fail‑safe operation and matching criticality levels in aeronautics.
- Low‑power patch consumption, redundancy, patch data rate and traffic constraints.
- Simulation & scalability
- System‑level simulation framework, metrics for AFC and WSN performance, turbulent flow modelling and scalability analysis.
- Standards‑oriented implementation
- Use of standardized interfaces and service‑oriented middleware to enable modular, interoperable AFC deployments.
Practical applications and who uses this standard
- Use cases:
- Design and prototyping of AFC systems for boundary‑layer control to reduce skin drag and improve fuel efficiency.
- Integration of dense sensor/actuator arrays on wings, control surfaces and fuselage patches for active flow management.
- Research platforms and testing environments for wireless avionics and intra‑aircraft WSANs.
- Typical users:
- Aerospace systems engineers, avionics architects and OEMs.
- Wireless sensor network designers and middleware developers.
- Certification engineers, R&D teams in aeronautics and academic researchers focusing on active flow control and onboard networking.
