“The Einstein probe satellite launched this time is one of the space science satellites established and implemented under my country’s Space Science Pilot Project (Phase II). It is also my country’s first large-field X-ray astronomy satellite, used to capture Einstein’s predictions. astronomical phenomena such as black holes and gravitational wave electromagnetic counterparts.” At the mobilization meeting, Cui Zhaoyun emphasized the importance of this mission to the team members.
This mission involves the “Princess and the Pea” who cannot tolerate a speck of dust. Several high-end cameras were installed on this payload, and the lenses had very high requirements for cleanliness. To this end, the operators also performed “dust-proof treatment” on the inner wall of the long 2-propylene rocket fairing.
The fairing usually consists of a basic structure with a composite skin and metal reinforcements. After being fixed with rivets, there will be very small debris in the gaps in the inner wall. These debris may fall onto the lens during fairing closure or flight vibrations. “General loads will not be affected by this, but considering the particularity of this mission, we sprayed a layer of coating on the inner wall of the fairing to seal in fine dust.”

Knowledge Posts
The “Thunder-R1” engine thrust vector control adopts a pump backswing technical solution. As the name suggests, a swingable high-pressure hose is set between the engine’s thrust chamber and the turbine pump. When the engine is performing vector control during operation, the turbine The pump is stationary and the thrust chamber is oscillated by the servo actuator. The name pump backswing engine actually comes from the perspective of the overall engine layout. This layout is based on the engine frame, and the frame and the thrust chamber are connected through a gimbal. Since only the thrust chamber swings, the swing mass and inertia are small, and the power requirements for the servo actuator are lower; since the turbopump does not swing, the engine swing profile is more compact, and the saved space provides the possibility to connect more rocket engines in parallel.
