Aviation Power has obtained patents related to titanium alloy shape correction molds, and the thermal shape correction molds improve the forming accuracy of the inner ring of the titanium alloy stator.

April 2 News, the State Intellectual Property Office information shows that China Aero-Engine Power Co., Ltd. has applied for a patent titled "A Heat-Forming Mold and Heat-Forming Method for a Titanium Alloy Static Inner Ring of a Curved Mother Line," with authorization announcement number CN116900097B, granted on March 31, 2026. The application publication number is CN116900097A, application number CN202310941441.0, with publication date March 31, 2026, filing date July 28, 2023. Inventors are Li Xinyan, Wu Yafeng, Zhang Hailun, Zhang Jie, Dang Wenzhe, Liu Chuanxiong. The patent agency is Xi'an Tongda Patent Agency Co., Ltd., patent agent Cui Fangfang. Classification codes are B21D3/10, B21D43/00, B21D37/16.

The patent abstract states that the invention discloses a heat-forming mold and heat-forming method for a titanium alloy static inner ring of a curved mother line, belonging to the field of sheet metal forming technology. The heat-forming mold includes a base, on which an adjustment pad is clamped. Alternately arranged on the adjustment pad are fan-shaped expansion blades and equal-width expansion blades. An inner conical ring is set inside the fan-shaped and equal-width expansion blades. The outer periphery of the mold holds the workpiece to be formed, and an outer heat insulation ring is set around the workpiece. The mold shapes the workpiece by driving multiple expansion blades to move radially via the inner conical ring, enabling high-precision processing of the titanium alloy static inner ring part. This is applicable to the heat-forming of the curved mother line titanium alloy static inner ring with a radial deep ring groove structure, solving the problem of low forming accuracy of the aircraft engine compressor stator inner ring, and ensuring the development requirements of the titanium alloy static inner ring of the curved mother line.

Aero-Engine Power was established on December 23, 1993, and listed on the Shanghai Stock Exchange on April 8, 1996. Its registered and office location is in Xi'an, Shaanxi Province. It is a leading enterprise in the domestic aircraft engine manufacturing field, with core products being aircraft engines, possessing deep technical accumulation and full industry chain advantages.

The main business scope includes manufacturing of aircraft engines and derivative products, foreign trade subcontracting of civil aircraft engine parts, and some non-aviation products manufacturing. The company's Shenwan industry classification is Defense Military Industry - Aerospace Equipment II - Aerospace Equipment III, involving concepts such as unmanned combat aircraft, new combat capabilities, and aircraft engines.

In terms of operational performance in 2025, Aero-Engine Power performed outstandingly. Its operating revenue reached 46.33B yuan, ranking first among 21 companies in the industry, far above the industry average of 11.47B yuan and median of 3.7B yuan, surpassing the second-place AVIC Shenyang Aircraft Company (44.66B yuan). In main business, revenue from aircraft engines and derivative products was 43.48B yuan, accounting for 93.84%. The company's net profit was 738 million yuan, ranking sixth in the industry, though below the first-place AVIC Shenyang Aircraft's 3.54B yuan and second-place AVIC Aircraft's 1.34B yuan, but above the industry average of 532 million yuan and median of 252 million yuan.
