Dynamic Pendulum Thrust Measurement System And Method

A dynamic pendulum thrust measurement system for measuring a thrust provided by a thruster using a dynamic pendulum thrust measurement method, the dynamic pendulum thrust measurement system comprising:

• a swing arm, the swing arm having a suspension end and a swing end, wherein the swing arm is disposed at a suspension height through the suspension end, the thruster is disposed on the swing end of the swing arm, thereby forming a pendulum structure;
• a driving device, the driving device raising a positioning point on the pendulum structure to a release height, and then causing the swing end of the pendulum structure to fall under an action of gravity, so that the pendulum structure performing a reciprocating swing process of a preset number of times of swing in a non-thrust set swing step and a thrust set swing step of the dynamic pendulum thrust measurement method respectively;
• wherein in the non-thrust set swing step, the thruster is in a closed state when the pendulum structure performs the reciprocating swing process, so that the pendulum structure performs a thrustless-assisted pendulum motion during the reciprocating swing process;
• wherein in the thrust set swing step, when the pendulum structure performs the reciprocating swing process and is provided with an energy, the thruster is started according to a preset number of times of start and a preset start state to correspondingly provide the thrust respectively, so that the pendulum structure performs a thrust-assisted pendulum motion during the reciprocating swing process;
• and
• a data capturing device used for respectively obtaining a thrustless-assisted swing datum of the pendulum structure when performing the thrustless-assisted pendulum motion in the non-thrust set swing step, and a thrust-assisted swing datum of the pendulum structure when performing the thrust-assisted pendulum motion in the thrust set swing step, thereby in an operation step of the dynamic pendulum thrust measurement method, the thrust provided by the thruster being calculated based on a difference between the thrustless-assisted swing datum and the thrust-assisted swing datum.
