Abstract
Shaft alignment is a critical factor in the design and fabrication of cruise missiles. It determines propulsion efficiency, structural integrity, and overall flight stability. These factors contribute significantly to minimizing environmental impact and limiting collateral damage. Precise alignment between the engine shaft and the airframe structure ensures optimal power transmission and aerodynamic performance. Misalignment can cause increased mechanical stresses, excessive vibration, premature bearing wear, and potential system failure, thereby compromising the missile's success rate. For this experiment, the objective is to examine the principles and methodologies associated with shaft alignment and its relevance to cruise missile propulsion systems by simulating the process using laser-based coupling alignment technology for a more accurate and efficient approach. Two rotating shafts are coupled together, and measurements were made to identify and correct angular and parallel misalignment. Measurements were obtained in both horizontal and vertical planes, and corrective adjustments were made by repositioning the machine’s feet according to calculated shims and movement values provided by the laser system. Using the data obtained, precision alignment strategies can be made within the broader framework of missile structural design and quality assurance protocols. There are many challenges posed by compact missiles, including their geometries, high rotational speeds, thermal expansion during sustained flight, and transient launch loads when considering the alignment of the engine shaft. By improving shaft alignment accuracy, engineers can enhance propulsion system longevity, reduce mechanical inefficiencies, and increase operational reliability. These findings contribute to the advancement of robust propulsion integration practices for future cruise missile systems.
