Some new information on the QC500, by @爱若丰狂SOYO历 on Weibo:
1. The designation first appeared in a publicly accessible procurement list from China’s aero-engine industry, lending it high credibility.
2. Initially referenced in a 2024 research paper by the Shenyang Aeroengine Research Institute (SARI, or AECC Shenyang), the QC500 is described as an aero-derivative gas turbine (AGT) "comparable in class" to the GE LM6000.
3. The known key characteristics of this engine include (but not limited to):
- A simple-cycle, aero-derivative gas turbine engine, classified as a lightweight high-power AGT. Its progenitor engine (base model) remains uncertain, although historical trends suggest that the QC500 may be derived from the CJ-2000/AEF-3500.
- The QC500 is a relatively rare "dual-output-shaft AGT". Unlike other conventional models with only a front or rear power output shaft, the QC500 supports simultaneous front and rear load transmissions.
- While the QC500 is mentioned in one of the paragraphs (picture 5) to be "in the same class" as the LM6000, yet the AGT has an actual maximum load/generation capacity reaching the 50MW range.
- As of present, the QC500 has been confirmed for offshore platforms usage, with design considerations for shock resistance. Hence, there is a high likelihood of marine propulsion/power generation variants of the AGT in the future.
4. According to AECC Shenyang's data, the full engine had completed over 4,000 hours of full-scale testing with favorable results by mid-2024. (For comparison, the LM6000's actual operating effectiveness is not good, and the utilization efficiency is low.）
5. Picture 1 is a simplified schematic of its external design, drawn by @爱若丰狂SOYO历 based on patent images, and is for reference only.
