During the Docking procedures Space station and cargo spacecraft can be connected to the grid for power generation…According to the Eighth Academy of Aerospace Science and Technology, after the core cabin is successfully docked with the cargo spacecraft, in the combined flight mode, in order to ensure the power generation capacity of each cabin and the cargo spacecraft, the core cabin and the cargo spacecraft The cargo spacecraft will be connected to the grid for power supply. At that time, the core cabin can provide up to 2,000 watts of power to the cargo spacecraft. Although compared with the “big family” of the core cabin, the cargo spacecraft has only one third of the power supply capacity of the core cabin, but at critical moments, the cargo spacecraft can also provide about 1,000 watts of power to the core cabin.
“The core cabin supplies power to the cargo spacecraft, mainly considering that the cargo spacecraft is installed at the stern of the core cabin, and the cargo spacecraft’s solar battery wings are small in size and are easily blocked by other combinations of the space station. The cargo spacecraft supplies power to the core cabin for the purpose of Responding to the very few special situations that may occur in the future space station, this also demonstrates the flexibility and reliability of the power supply of the entire space station assembly.” Wang Zhenxu, chief designer of the power supply subsystem of the cargo spacecraft, introduced. In order to receive the 2000 watts of power gift from the core cabin, the cargo spacecraft itself needs to undergo a high-voltage grid-connected adaptation process. In response to the above problems, the developers of the Eighth Academy of Aerospace Science and Technology conducted a series of verification experiments to ensure that the normal operation requirements of the cargo spacecraft are met.
When the cargo spacecraft is connected to the core cabin for power supply, how to deal with the excess electricity? Developers have their own methods. Wang Zhenxu introduced that in the Tianzhou No. 2 cabin, a shunt regulator is installed, through which the excess electricity of the solar battery wing can be shunted. In the future, there will be the challenge of joint power supply of multiple combinations, but the power sub-system can always adapt. This is the intelligent management of the power sub-system in the space station era.
The newly advance variant of the Long March –Chang Zheng 7 Carrier Rocket has more than 130 improvements to make its performance better] This mission is the third launch of the Long March 7 carrier rocket. 4 years have passed since the Long March 7 Yao-2 launches. During this period, the model team Carried out a large number of optimized and improved designs, which not only realized the technological leap from “zero window” to “narrow window” launch, but also through more than 130 improvements such as simplifying and optimizing the on-board measurement system, and optimizing the tank pressurization design. The rocket has better performance and is more conducive to batch production and high-density launch.
Simplify and optimize the design of the on-arrow measurement system. The measurement parameters used for research have been deleted. The number of measuring points on the arrow has been reduced by about one-third, and the number of stand-alone measurement systems has been reduced by nearly half. This not only saves costs, but also helps to improve the sampling accuracy of some key parameters. In addition, this rocket also uses a high-rate Ka-band space-based measurement system. Compared with the S-band measurement system used by the Long March 7 Yao-2 launch vehicle, the transmission code rate has been increased by more than 20 times, realizing the full range of rocket flight telemetry. No blind spots.
Optimize the design of pressurization of the tank on the arrow. Combining the analysis of the results of the previous two flight tests, the booster reduces one tank booster gas cylinder without affecting normal use, and optimizes the boost pressure control bands of each module tank to increase the boost pressure. Utilization of gas. The rocket boost, the first-stage tail end and the first-stage transition section are changed from composite coating to ordinary coating. After the improvement, the construction process is simplified and the production cycle is shortened. Taking the first-level post-transition section as an example, the improved production cycle has been shortened from about 18 days to 13 days, laying the foundation for subsequent mass production. Focusing on zero-window launch, focusing on flight success or failure, sorting out one detail by one detail, fully identifying the weaknesses in the design and making improvements, in addition, drawing inferences about other rocket quality issues from the mechanism to ensure the complete success of this launch mission….
