Technical Field

The invention relates to the technical field of geomagnetic energy storage on-orbit delivery, in particular to a near space experiment system for geomagnetic energy storage delivery.

Background

Before a spacecraft uses a geomagnetic energy storage on-orbit delivery method to carry out a space orbit flight task, sufficient experiments must be carried out for verification. The relative delivery speed of on-orbit delivery can be effectively used only when the relative delivery speed reaches more than 100m/s-300 m/s. If experiments are carried out near sea level, when the relative delivery speed reaches the above-mentioned magnitude, the resistance effect of air increases sharply, so that the use of geomagnetic energy storage is far from providing enough magnetic torque to overcome the air resistance, and aerodynamic resistance in the track is basically nonexistent.

In addition, the centrifugal acceleration of the delivery rotation is in inverse proportion to the rotation radius, and for the delivery speed with the magnitude, if the centrifugal acceleration is controlled within the magnitude of 100g, the rotation radius is in the magnitude of 10m-100 m. Therefore, if a vacuum facility meeting the requirements is built on the ground and is guaranteed not to be influenced by factors such as the distribution of the geomagnetic field, the investment of the vacuum facility built on the ground is necessarily huge.

At present, no experiment system for geomagnetic energy storage on-orbit delivery is disclosed in the prior art, and therefore, it is urgently needed to research and design an applicable experiment system for geomagnetic energy storage delivery verification.
