星河动力空间科技有限公司 Galactic Energy- Galaxy Power (Beijing) Space Technology Co., Ltd. Located in Block D, Aviation Technology Plaza, E-Town, and Beijing – Beijing – China – People’s Republic of China ….Galaxy Aerospace is the first private aerospace company in China to achieve successful continuous launches, the first to send commercial networked satellites into a 500km sun-synchronous orbit, and the first to master the ability to launch multiple satellites with one carrier rocket.
[The Pallas-1 launch vehicle successfully completed a series of fairing tests]
On the 25th July 2024 The latest news from Galaxy Power; Recently, the company completed a series of static, modal, and separation tests on the Pallas-1 launch vehicle fairing, all of which were successful. The Pallas-1 series of launch vehicles are compatible with fairings with diameters of 3.35m, 4.2m, and 5.2m to meet the needs of different satellite customers. The fairing used in this test is one of the series of fairing products independently developed and designed by Galaxy Power, and is consistent with the status of the Pallas-1 Yao-1 flight test product.
The Pallas- 1 has a maximum low-orbit carrying capacity of 8 tons, with seven 50-ton liquid oxygen-kerosene engines in parallel in the first stage. It is scheduled to make its maiden flight at the end of this year….
Recently , Galaxy Aerospace completed a series of static, modal and separation tests on the fairing of the Pallas-1 launch vehicle, and all the tests were a complete success!
The Pallas-1 series of launch vehicles are compatible with fairings with diameters of 3.35m, 4.2m, and 5.2m to meet the needs of different satellite customers. The fairing used in this test is one of the series of fairing products independently developed and designed by Galaxy Power, and is consistent with the Pallas-1 Yao-1 flight test product. The fairing adopts a von Karman shape, which has the advantages of low flight aerodynamic resistance, light structural mass and easy operation.
The fairing end cap is made of high-strength ablation-resistant composite material, a large area of honeycomb sandwich composite material structure, and a metal frame structure at the rear. The fairing separation system adopts a “hinge-spring” half-cover rotation separation scheme, and the lateral and longitudinal separation unlocking devices both use point-type explosive bolts, which have small impact during the separation process and high separation reliability.
The static test of the fairing assessed the fairing’s ability to resist external loads and verified the structural strength. The test achieved the intended purpose and obtained relevant data. The modal test obtained the fairing’s modal parameters, providing a basis for structural dynamics model modification and fairing separation calculation.
The fairing separation test fully verified the correctness of the fairing separation system design, obtained the collision boundary data between the fairing separation body and the payload, assessed the adaptability of the structural system to the separation concentrated force load and the impact load of pyrotechnics, and obtained important mechanical environment parameters.
The complete success of the fairing series tests indicates that Galaxy Aerospace has the ability to quickly design, analyze and test large liquid rocket fairings, laying a solid foundation for the company’s subsequent model development.
