The recyclable rocket is expected to make its "debut" at the Hainan Commercial Space Launch Site next yearThe development cost of launch vehicles is quite expensive, and if it is recycled and reused, the cost will be greatly reduced. Reporters learned from Hainan International Commercial Space Launch Co., Ltd. on November 29 that the recyclable launch vehicle Nebula-1 (XY-1) developed by Jiangsu Deep Blue Aerospace Co., Ltd. is expected to complete the test arrowhead at the Hainan Commercial Space Launch Site in 2024. fly.At present, the Hainan Commercial Space Launch Site has entered the critical stage of forming its launch capabilities. It plans to complete hardware construction by the end of this year and achieve regular launches in 2024. The Hainan Commercial Space Launch Site is my country's first commercial space launch site under construction, with a total budget investment of more than 4 billion yuan. After the project is completed, it will mainly undertake domestic and foreign rocket launch business, which will further enhance China's commercial rocket launch capabilities.Recently, the Deep Blue Aerospace XY-1 model team visited the Hainan Commercial Space Launch Site for inspection. Du Pengfei, chief engineer of XY-1, said that Deep Blue Aerospace has solid theoretical foundation and rich engineering experience in the development of liquid launch vehicles, liquid rocket engines, and advanced aerospace vehicles. It also has expertise in pinbolt engine technology, rocket and engine component 3D printing technology, and vertical recycling It has unique advantages in terms of technology and ignition-free separation technology. He hopes to use the Hainan Commercial Space Launch Site to continue to verify many achievements in the aerospace field and complete the first flight of the XY-1 rocket.Liu Hongjian, deputy general manager of Hainan International Commercial Space Launch Co., Ltd., said that a communication mechanism will be established with Jiangsu Deep Blue Space Co., Ltd. to promote the agreement of cooperation intentions and the establishment of a special work class, and ultimately realize the Deep Blue space rocket soaring into the sky at the Hainan Commercial Space Launch Site.
First flight is imminent | DeepBlue Aerospace accelerates test delivery of "Nebula-1" rocket engine to fully guarantee first flight missionAfter a successful start in the 2025 engine test, the liquid oxygen-kerosene engine independently developed by Deep Blue Aerospace has entered the high-frequency normalized test stage. Relying on the newly completed test bench at the Jinan test base, Deep Blue Aerospace's engine manufacturing and testing will also be accelerated, providing strong guarantees for the high-frequency calibration test and batch delivery of the engine of the "Nebula-1" carrier rocket.As a strategic commanding height in the global commercial aerospace competition, reusable engine technology directly determines the success or failure of rocket recovery. The Deep Blue Aerospace innovation team focuses on the needs of the next generation of reusable rockets and independently develops a reusable liquid oxygen-kerosene engine with excellent performance indicators, multiple starts, a wide range of thrust adjustment, and a high thrust-to-mass ratio.This type of engine has been mass-produced in 2024, and the first batch of products will be installed on the milestone "Nebula-1" reusable carrier rocket. As China's first commercial medium-sized reusable rocket, "Nebula-1" will carry out its first orbital launch and vertical recovery verification in the second quarter of this year, boosting the efficiency of my country's satellite Internet constellation deployment.While steadily advancing the "Nebula 1", Deep Blue Aerospace has begun to lay out the development of the next-generation large-scale carrier rocket "Nebula 2". The first stage of "Nebula 2" uses 11 "Thunder-RS" engines in parallel, and its low-Earth orbit carrying capacity will jump to 25 tons, which can cover multiple scenarios such as high- and low-orbit satellite networking and manned spacecraft. It is planned to conduct the first flight test in 2026.Compared with its peers who focus on single technological breakthroughs, Deep Blue Aerospace has built an integrated R&D, manufacturing and testing capability for the entire chain of "power-rocket body-launch": Deep Blue Aerospace independently developed the "Thunder-RS", the largest thrust open-cycle liquid oxygen-kerosene rocket engine currently under development in China. It has completed a semi-system test in December 2024 and will conduct a full-system test of the entire machine in the first quarter of this year. The engine adopts a modular design and has the advantages of high reliability, high thrust, multiple starts, deep throttling, non-toxicity and environmental protection. It is tailored for the "Nebula-2" large launch vehicle, supports more than 10 times of reuse, and can significantly reduce the cost of a single rocket launch.
