A test device for simulating on-orbit solar irradiation of ion thrusters

Abstract

The invention discloses a test device for simulating solar irradiation when an ion thruster is in an orbit which can carry out a simulation test of the solar irradiation under an in-orbit working condition of the ion thruster and can simulate a variety of working conditions, and the efficiency of the simulation test is high. In the test device for simulating the solar irradiation when the ion thruster is in the orbit, a plurality of irradiation sources are evenly arranged on a ring to form an annular irradiation structure; the ion thruster is positioned at the center of the ring; the annular irradiation structure and the ion thruster can rotate relative to each other and the axis of rotation is the axis of the ion thruster; a radiometer is mounted on the outer surface of the ion thruster; an industrial PC can turn off or turn on the corresponding irradiation source according to an operating position of the ion thruster and different angles of the solar irradiation and control a relative angle between the annular irradiation structure and the ion thruster, so as to simulate reception of the solar irradiation under the in-orbit working condition of the ion thruster; and the industrial PC is also used to adjust working parameters of the irradiation sources according to an irradiation dosage of the irradiation sources measured by the radiometer to simulate the irradiation dosage received under the in-orbit working condition of the ion thruster.

Description

technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to a test device for simulating on-orbit solar radiation of an ion thruster. Background technique [0002] When simulating on-orbit solar radiation tests for ion thrusters, the traditional method is to use a solar radiation simulator to directly irradiate the thruster at a fixed angle. The thruster cannot move and can only simulate the sun at a single point on orbit. In the irradiation test, the cost of the solar simulator is high and the position of the thruster needs to be adjusted continuously during the test. The whole test system is complex and the efficiency of the test is low due to the large loss of solar radiation dose. Therefore, it is necessary to design a simple and low-cost simulated ion thruster on-orbit solar radiation test scheme to conduct solar radiation simulation tests under the thruster's on-orbit working conditions.
