High-orbit spacecraft launching method based on multi-rocket combination

[0036] A method for launching a high-orbit spacecraft based on a combination of multiple rockets, used to launch a target spacecraft 1 to a high orbit, such as figure 1 As shown, the method includes the following steps:

[0037] S1. Launch the target spacecraft and the supply spacecraft to low orbit respectively by rocket;

[0038] S2. The target spacecraft docks with the supply spacecraft in low orbit;

[0039] S3. After docking, the supply spacecraft supplies the propellant carried by itself to the target spacecraft, and undocks after the supply ends;

[0040] S4. After the target spacecraft is supplied with propellant, it transfers to a high orbit through its own power.

[0041] Wherein, the target spacecraft 1 includes a load compartment, a power compartment and a propellant compartment, wherein the propellant compartment includes an oxidant compartment for storing oxidant and a fuel compartment for storing fuel. Such setting makes the target spacecraft 1 not only carry t

[0052] The difference from Embodiment 1 is that in S1, there are two or more supply spacecraft 2, and each supply spacecraft 2 is launched to different low orbits by rockets. Such setting enables the target spacecraft 1 to transfer to each low orbit in sequence from low to high, and to carry out propellant replenishment after docking with each supply spacecraft 2 on each low orbit, so that the target spacecraft 1 can be transferred to 1 is launched into a higher orbit.

[0053] For example, a certain type of rocket has a maximum carrying capacity of 15 tons for low-earth orbit (LEO), 12 tons for medium-earth orbit (MEO), and 7 tons for geosynchronous orbit (GEO). GTO) has a maximum carrying capacity of 4 tons. Now it is necessary to launch a 10-ton payload into lunar orbit, a task that this rocket cannot perform.

[0054] Specific launch: Arrange two rockets to launch the target spacecraft 1 and the supply spacecraft 2 from the earth 5 to the same low-earth orbit 6, and then ar

[0058] The difference between it and the second embodiment is that this embodiment demonstrates the process of launching a 5-ton load into the orbit of Mars by using the combination of the above-mentioned rockets through the method provided by the present invention.

[0059] For example, a certain type of rocket has a maximum carrying capacity of 15 tons for low-earth orbit (LEO), 12 tons for medium-earth orbit (MEO), and 7 tons for geosynchronous orbit (GEO). GTO) has a maximum carrying capacity of 4 tons. Now it is necessary to launch a 5-ton payload to Mars orbit 14, which is not possible for this type of rocket.

[0060] Specific launch: Arrange two rockets to launch the target spacecraft 1 and the supply spacecraft 2 from the earth 5 to the same low-earth orbit 6, and then arrange a rocket to launch another supply spacecraft 2 from the earth 5 to the synchronous transfer Track 9.

[0061] Among them, the launch vehicle A is used to launch the target spacecraft 1 to the low
