Fibre optics for distributed environmental condition and/or air quality sensing such as, but not limited to, sensing air quality in enclosed areas of an aircraft such as the passenger cabin. Fibre optics can be used for sensing and for communication and are therefore well suited to the distributed sensing of environmental conditions such as temperature, relative humidity, gas and particulate composition within spaces of the aircraft e.g. the cabin, cargo space, cockpit, electronics bay etc. and in related systems such as the environmental control system (ECS), the cabin recirculation system, bleed air system etc.

Environmental condition sensing system

Systems for and methods of manufacturing a ceramic matrix composite include introducing a gaseous precursor into an inlet portion of a reaction furnace having a chamber comprising the inlet portion and an outlet portion that is downstream of the inlet portion, and delivering a mitigation agent, such as water vapor or ammonia, into an exhaust conduit in fluid communication with and downstream of the outlet portion of the reaction chamber so as to control chemical reactions occurring with the exhaust chamber. Introducing the gaseous precursor densifies a porous preform, and introducing the mitigation agent shifts the reaction equilibrium to disfavor the formation of harmful and/or pyrophoric byproduct deposits within the exhaust conduit.
