Patent ID: 11276159

Abstract:
Embodiments described herein may be applied to monitoring and evaluating rocket engine and other reusable components' health by tracking full-field stochastic patterns using Digital Image Correlation (DIC) to detect deformation. In particular, rocket engine cylindricity enables pre-flight and post-flight non-destructive inspection utilizing a turntable to detect local fatigue. In accordance with embodiments of the present disclosure, a rocket engine may undergo a DIC process, where the rocket engine is rotated via a turntable. Accordingly, the use of a turntable allows a single camera DIC setup to acquire data indicative surface measurements about the entire rocket engine. The rocket engine may then be flown and subsequently recovered. After recovery, the rocket engine again may undergo DIC processing, where the rocket engine is rotated via the turntable. The pre- and post-flight data may be compared to provide evidence of the existence of a deformation or lack thereof.
