Global Aeroengine Low Pressure Turbine Discs (LP Turbine Discs) Market Strategic Research Report

Scope of the Report

The global Aeroengine Low Pressure Turbine Discs (LP Turbine Discs) market size is predicted to grow from US$ 939 million in 2025 to US$ 1,427 million in 2032; it is expected to grow at a CAGR of 6.2% from 2026 to 2032.

The aeroengine low pressure turbine discs are disc-shaped core rotating components installed at the end of the low-pressure turbine rotor. Its main function is to fix the working blades of the low-pressure turbine and transfer the mechanical work extracted from the exhaust gas flow to the fan and/or low-pressure compressor to generate the engine's main thrust. The demand for low-pressure turbine disks is primarily driven by the strong commercial aviation market, namely, orders placed by aircraft manufacturers (such as Boeing and Airbus) with engine manufacturers when launching new models and upgrading existing fleets, and the resulting large aftermarket maintenance and overhaul market. Its upstream supply chain begins with metal raw material suppliers (providing titanium, aluminum, nickel, etc.), with key links being special alloy manufacturers (producing titanium alloy and nickel-based alloy billets) and large forging suppliers, who provide smelted and forged disk blanks. Midstream precision manufacturers are responsible for precision machining, heat treatment, and testing, ultimately producing qualified disks. Downstream, they are delivered directly to OEMs for engine assembly and ultimately delivered to aircraft manufacturers and airlines along with the engines, forming a tight supply chain spanning the entire lifecycle from raw materials to in-flight operation. In 2025, the production of aeroengine low pressure turbine disks for aero engines will be approximately 8,000 units, with an average selling price of approximately US$120,000 per unit, a gross profit margin of approximately 35%, and a single-line capacity of approximately 150 units per year.

The core driving factors for the market of aeroengine low pressure turbine disks for aero engines can be summarized in the following three points: First, fleet expansion and replacement demand: The recovery of global air passenger demand and the improvement of fuel efficiency requirements have driven the delivery of new-generation high-bypass turbofan engines, directly boosting the market demand for new turbine disks. Second, replacement and MRO market: As the age of in-service aircraft increases, the replacement demand for low-pressure turbine disks, as key short-life rotating components, continues to expand in the maintenance, repair, and overhaul (MRO) stage, forming a huge replacement market. Third, supply chain self-sufficiency strategy: Geopolitical factors have prompted countries (especially emerging markets such as China) to attach importance to the security of the aero engine supply chain and increase investment in independent research and development and capacity building for core hot-end components, including low-pressure turbine disks.
