Empirical Modeling of Structural Weight Fraction in Small Aircraft: A Power-Law Approach for Ultralight, LSA, VLA, and Part 23 Categories

Abstract In aircraft design, the structural skeleton weight fraction—defined as the ratio of the primary airframe weight (including wings, fuselage, empennage, and landing gear) to the maximum takeoff weight (MTOW)—plays a critical role in preliminary sizing and performance estimation. This article derives and analyzes an empirical equation, f(M)=1.47×M^(−0.35)+0.20, where M is MTOW in kilograms, fitted

Typical Process of a CFD Simulation

Computational Fluid Dynamics (CFD) is a computer-aided method used to simulate fluid flow in both closed and open systems. CFD allows engineers to predict and analyze the behavior of gases and liquids within a virtual model, accelerating the development of new products and making the process more cost-efficient. A typical CFD simulation process involves creating

What is Structural Analysis (FEA) and where is it used?

Structural analysis, also known as Finite Element Analysis (FEA), is a powerful computational method used to predict the behavior and load-bearing capacity of structures under various conditions. This technique enables engineers to assess and refine designs before physical prototypes are built, ensuring optimal performance and safety. FEA is applied in numerous industries, including mechanical engineering,
