  • Aircraft sizing is a multidisciplinary process encompassing aerodynamics, structures, propulsion, and systems engineering to determine the optimal configuration of an aircraft to fulfill specific mission requirements. It involves defining key parameters such as payload capacity, range, endurance, speed, and operational constraints. Engineers employ mathematical models, empirical data, and computational tools to iterate through design options, balancing conflicting requirements to achieve an optimal solution.
  • Flight simulation is a critical tool in the aircraft sizing process, providing a virtual environment to assess the performance and behavior of proposed designs. High-fidelity simulations replicate the aerodynamic forces, propulsion characteristics, and control responses of the aircraft under various flight conditions. By subjecting the virtual model to simulated flight maneuvers, mission profiles, and environmental conditions, engineers can evaluate performance metrics, such as climb rate, turn radius, fuel consumption, and stability margins.
  • Through iterative refinement, flight simulations enable engineers to optimize the aircraft’s configuration, including wing geometry, propulsion system selection, control surface sizing, and weight distribution. Sensitivity analyses allow for the identification of design trade-offs and the exploration of design uncertainties. Furthermore, simulations aid in assessing the aircraft’s compliance with regulatory requirements, including safety margins, handling qualities, and environmental standards.
