I am a student of Aerospace Engineering, currently I am one year away from completing my degree. For my Electric Routing class I was asked to recreate in Catia the fire system in the cargo bay of an airplane and obviously justify why I made the decisions, for now I only have to decide which model I'm going to work with, its specifications, etc.
Looking for information on the internet, I decided that I will work with the Airbus A340 Lower Deck Cargo Compartment Class C. Doing a little research I understood that when there is a fire in this bay, from the cockpit the area is sealed and a percentage of Halon is released 1301.
But 2 questions arose that I would like to know:
- How many and what type of fire sensors does this family of aircraft use (the type or model would be of great help)?
- Does anyone know how this system is "wired" in general? I mean, in series, in parallel, which is better? How does the smoke sensor connect to Halon pumps?
This is information that I do not known where to find and I do not know if it is classified by the company and I need it to do my Catia model using the electronic Harness Discipline. For now I will be dedicated to modeling the part of my fuselage with the low cargo bay.
P.S: If you know of any regulations that I could read to better understand this topic, I would greatly appreciate it.
