Problems solved by technology

[0006] Due to the coupling between the injection angle of the electric propulsion plume and the attitude adjustment of the solar cell array itself, a multi-degree-of-freedom attitude test condition will be generated. The existing tooling equipment is not enough to support the smooth development of the plume test. The complexity of the particle environment also increases the difficulty of simulation

Embodiment 1

[0033] This embodiment includes a tooling lug 7 with a rotation angle dial A8, which is used to simulate the angle of rotation attitude adjustment of the solar cell array; a two-degree-of-freedom slider guide turntable 6 with a rotation angle dial B9, which is used to simulate the electric propulsion in the The swing angle on the star; the assembly of the test piece bracket 5, which is used to place the test piece, including but not limited to single solar cells, wires, coated glass cover sheets, etc. The whole test tooling contains three angle dials, which are recorded as angle dial A, angle dial B and angle dial C. The angle dial A8 is installed on the tooling lug 7 for measuring the angle of rotation α, and the angle dial B9 is installed On the slider-guided turntable 6, it is used to measure the rotation angle β, and the rotation angle dial C10 is installed on the combination composed of four test piece brackets 5 for measuring the rotation angle θ.

Embodiment 2

[0039] Regarding the locking of the guide rail slider, the current existing slider locking mechanism can be used, that is, the tension mechanism with an elastic pressure block is designed inside the slider, and the screw (or wrench) used to adjust the tension is connected to the outside of the slider. When the slide block needs to slide, the tensioning mechanism is released, the slide block can slide, and when the slide block reaches the target position, the slide block can be locked by a screw rod (or a wrench). The specific models of the guide rails and guide rail sliders involved can be the built-in double-axis linear motion guide rail model SGR10, and the locking positioning slider model SGB10.

[0040] The hinge mechanism between the tooling lug 7 and the slider guide turntable 6 adopts an existing mechanism, specifically, the slider guide rail turntable 6 and the tooling lug 7 are linked by a threaded rotating shaft pin (or a screw rod), and the tooling The lifting lug 7...

The invention provides a multi-degree-of-freedom pose-adjustable electric propulsion plume test tool.

Description

technical field [0001] The invention belongs to the technical field of equipment tooling, in particular to an electric propulsion plume test tooling with adjustable multi-degree-of-freedom poses. Background technique [0002] current technology: [0003] Electric propulsion is a device that can generate thrust without relying on the combustion of chemical propellants. It has the characteristics of high specific impulse, long life and low thrust. In the future, electric propulsion will be widely used on satellite platforms to ensure that the satellite maintains a fixed orbital position during orbital operation, and at the same time increase the load capacity of the satellite. [0004] Solar arrays are an important device for powering satellite payloads. The solar cell array can generate a steady stream of electric energy through the photoelectric effect, meet the power demand of the satellite platform and load in the illuminated area, and charge the battery to meet the powe...
