What is it about?
This paper introduces a mathematically efficient and more reliable way to calculate the temperature of gases used in aerospace engineering, like air or fuel mixtures. Engineers often use NASA polynomials, which are mathematical equations, to predict how temperature changes in high-speed flows, such as in jet engines or spacecraft. However, finding the temperature using these polynomials can be tricky and time-consuming. This paper presents a new method that simplifies the process, making it quicker and more accurate. The method also avoids potential errors that can happen with traditional approaches. By improving temperature calculations, this research can help engineers design better engines and systems for high-speed flight, reducing the time and effort needed for these critical calculations.

Why is it important?
What makes this work unique is its development of a faster, more efficient method for calculating temperature from energy equations using NASA polynomials, which are widely used in aerospace engineering. Traditionally, engineers rely on iterative methods to solve these equations, which can be slow and prone to instability, especially with the complex conditions in high-speed flows like those in hypersonic vehicles or combustion engines. This new method provides a closed-form solution, meaning it avoids the need for repetitive calculations and produces results quickly and accurately in fewer steps.
Perspectives
This publication offers a practical solution to a common challenge in aerospace engineering: efficiently calculating temperature using NASA polynomials. The authors provide a faster, more reliable method that avoids the instability of traditional iterative approaches while maintaining accuracy. This advancement is particularly timely given the increasing complexity of systems like hypersonic aircraft, where precise temperature control is critical. By reducing computational costs and offering broader applicability beyond aerospace, this work has the potential to impact devices and problems in high temperature fluids.
