国内首款全碳纤维复合材料火箭企业，完成天使轮融资

Core Viewpoint - The article highlights the recent angel round funding of several million yuan completed by the domestic commercial aerospace company, Weiguang Qihang, which focuses on developing medium-sized reusable launch vehicles using advanced carbon fiber technology and innovative engine designs [2][4]. Company Overview - Weiguang Qihang was established in March 2025, led by a core team with extensive experience in rocket and missile research and development, including national-level researchers [2]. - The company has developed a closed-loop capability covering design, materials, manufacturing, and launch, with a focus on vertical integration to ensure technical consistency and cost control [2]. Technological Innovations - The WG-1 Weiguang No.1 medium-sized liquid reusable launch vehicle is the world's first to integrate three core technologies: full-flow staged combustion cycle, carbon fiber composite materials, and liquid oxygen-methane [2]. - The use of carbon fiber technology allows for a 40% weight reduction in the rocket's storage tank compared to traditional metal tanks, significantly enhancing payload capacity and economic efficiency [3][4]. - The company has successfully manufactured and tested carbon fiber storage tanks with diameters of 1.4 meters and 3.35 meters, and is currently working on a 3.8-meter diameter tank, which will fill a technological gap in the domestic market [3]. Engine Development - The Huaguang No.1 engine is the first in China and the third globally to adopt a full-flow staged combustion cycle, achieving a fuel combustion efficiency of over 99%, which can increase the rocket's payload capacity by 30% [4]. - This engine design is complex, requiring the management of two pre-combustion chambers for liquid oxygen and methane, leading to higher efficiency and better propellant utilization [4]. Market Context - The Chinese commercial aerospace sector is highly competitive, with 38 companies vying for limited launch orders, leading to aggressive pricing strategies from established players [5]. - New entrants like Weiguang Qihang face significant challenges in this competitive landscape, where traditional aerospace giants and international companies like SpaceX maintain a strong market position [5].
