The dynamic seals used for aircraft gearbox are of precision design and undergo stringent quality checks for obtaining clearance for aircraft fitment.These dynamic seals are capable of operating under severe environmental conditions with high reliability and very low leakage rate. Accessory Gearbox (AGB) Housing is one of the most critical components of a gas turbine engine that lies between the core engine & the aircraft. The accessory gearbox is generally driven by the N2 shaft (connecting the high-pressure turbine to the high-pressure compressor) and in turn drives the engine accessories Gear and bearing design are currently out of the scope of this paper and can be addressed in future work. Design Attributes . 841605. Here are two pictures of the helicopter from that show. Carburised steel is the material of choice for gears in aircraft. This choice is made because gears in aircraft have to perform maximally under higher speeds, higher loads, and higher surface temperatures than many other gears used in other vehicle engines.
