 Architecture


Scope

This is the top-level document for the 2023-2024 AEAC competition aircraft “Pegasus”. These documents describe the purpose, function, and decisions made relevant to the design and use of the remotely piloted aircraft. It has been divided into sub-sections (in no particular order) which hope to offer a global overview of the design and implementation of all systems, as well as how they interface with each other.

Ultimately, this document serves as a “reference manual” for Pegasus, and should contain necessary information for the usage and support/maintenance of Pegasus. Justifications for design decisions and background knowledge should be provided as references, external links, or as subpages. This document seeks to state how the Pegasus system works, and not necessarily why it was chosen to work in that way.

Updates

If you are editing this document, please remember to update the changelog and modify the version ID (found in the table at the top of the page).

This document will be considered controlled from October 1st onwards. Any changes after that point must follow the formal RFC process. Ping Anthony Luo for more details.

Please make your RFC using the following link: 2024 Request(s) for Change(s)

Standards

Standards section should only include standards that this system is abiding by and exclude other standards that aren’t relevant or necessary.

Please try and include a version of a the standard you’re referencing (e.g. “CAD Guidelines V. 17”).

BOM

This lists all of the components that constitute the configuration of a drone that we wish to fly at competition in May 2024. Some parts may be listed as “Optional” (), in which case they will be they are not strictly necessary for flight but may be useful in improving system performance.

Here, “Quantity” refers to the number which is needed for a functional drone.
