The ASHLEY* project was a European aerospace reseach program, which built upon the work previously done in SCARLETT (in which AcQ also participated). It extended the concept of Distributed Modular Electronics (DME) to new applications in an aircraft. A total of 36 organisations from 13 countries participated in this project.

AcQ was involved in the development of the ASHLEY Fuel System demonstrator. This demonstrator aimed to develop and validate several new technologies for sensing and control related to an aircrafts fuel pumps and tanks. For this demonstrator, AcQ developed a number of novel technologies:

– A scalable and portable AFDX IP core in VHDL and associated configuration tooling.

– A smart transducer platform; this is a small, low-power system for multiple types of sensing and actuation applications.

– A high-performance configurable I/O router, the Optical Interrogator Blade. This board gathered data acquired data from optical sensors and routed this data to AFDX, based on the specified configuration. This board used SYSGO PikeOSĀ® as its operating system and the configuration toolchain was fully integrated with the PikeOS environment.

*ASHLEY is short for “Avionics Systems Hosted on a distributed modular electronics Large scale dEmonstrator for multiple tYpes of aircraft”.
