This work is to present the design and development of a vertical static thrust bed (VTSB) for solid propellant rocket motors. The setup consists of a motor mount, load cell holder, amplifier, and load cell to measure the impulse and to know the rocket thrust with different classes of rocket motors ranging from A class to F class, different nozzles, and new kinds of fuel for amateur rockets. This vertical test bed was designed and assembled in Autodesk Fusion360®. The thrust bed was tested using a KNSU rocket motor. The results of thrust and total impulse values are comparable to the literature. The testbed is safe to demonstrate and the results obtained are satisfactory. The test stand can be used for the motors with specific impulse up to 100 N s.

摘要

This work is to present the design and development of a vertical static thrust bed (VTSB) for solid propellant rocket motors. The setup consists of a motor mount, load cell holder, amplifier, and load cell to measure the impulse and to know the rocket thrust with different classes of rocket motors ranging from A class to F class, different nozzles, and new kinds of fuel for amateur rockets. This vertical test bed was designed and assembled in Autodesk Fusion360®. The thrust bed was tested using a KNSU rocket motor. The results of thrust and total impulse values are comparable to the literature. The testbed is safe to demonstrate and the results obtained are satisfactory. The test stand can be used for the motors with specific impulse up to 100 N s.
