AI Technical Summary

Benefits of technology

In this patented technical effect that uses advanced mathematical techniques such as Failure Physics Analysis (FE) or Finite Element Method (FinE), we developed an algorithm called Quantum Optimization Algorithm(QOAG). It allows us to predict how well certain parts will fail during use without having them actually break down over time. By combining these predictions with physical experiments like Fluid Dynamics Experimentation (FDX) data from different locations around our planet, researchers were able to identify which part was most likely affected first. Overall, QoGAA improves the quality control process and reduces manufacturings costs while also enhancing its overall performance capabilities.

Problems solved by technology

Technological Problems addressed in this patented technical problem include improving the efficiency and lifespan (the number of hours) of mission critical equipment systems, particularly when compared to other types of structures. Specifically, current methods involve optimizing specific parts called "gutters," which can reduce stress levels over longer periods without increasing their size. However, these techniques may result in insufficiently long durations during flight operations where the payload needs to stay within acceptable limits. To address this issue, some companies propose solutions involving analyzing failures caused by different sources including temperature fluctuate, moisture content, impact force, vibration, etc., making them easier to identify root causes beforehand. Additionally, while previous designs were mostly static ones, dynamic simulations showed that the use of harmonics could improve upon safety measures against damage from external forces.
