The SASA Sapienza Flight Team that participates Design/Build/Fly (DBF) competition presents an aircraft configuration case using modeFRONTIER, with various aerodynamic tools in order to find the optimal aircraft design. The configuration focuses on minimization of shaft power and wing area.
Multdisciplinary Design Optimization Applied to the Conceptual Design of a Small Unmanned Aerial Vehicle
The use of UAV aircraft has been increased in many sectors of society such as military defense, public security, search and rescue, remote sensing, agriculture control among others. This work develops a multidisciplinary optimization methodology to create the conceptual design of a small UAV, involving the areas of aerodynamics, structures and stability. The optimization, implemented in the commercial software modeFRONTIER, analyzes several configurations, looking for an aircraft with less mass, and that meets the project restrictions. The results are compared to a previously designed prototype, which was established as a reference model, seeking to reduce its mass and improve their characteristics.
Aerodynamic Structural and Esability Design of a Mini-VANT

Coupled modeFRONTIER - FIRE Approach for ICEngine Intake Port Optimization
Internal Combustion Engine (IC-Engine) efficiency and emission characteristics are at great extent, governed by the details of the intake port-combustion chamber arrangement. In this context, the discharge coefficient and swirl/tumble numbers, are commonly used to characterize the intake port with respect to the volumetric efficiency and, at least partly, to the combustion of both diesel and gasoline engines.
Increasing energy efficiency of a gasoline direct injection engine through optimal synchronization of single or double injection strategies
This paper explains the numerical procedure that couples a 3D model of the in-cylinder processes to modeFRONTIER in order to study into detail a moderate-load moderate speed condition, where the air-to-fuel ratio is maintained lean.
CFD Analysis and Multi-Objective Optimization of a Diesel Engine for Automotive Applications
The goal of the study was to develop a light-duty common-rail engine with low emissions. The process consisted in an experimental analysis (including performance and acoustic tests and characterization of the fuel injection system), model configuration and validation and multi-objective optimization.
Automatic Shape Optimization of Aerodynamic Properties of Cars
The aim of this work is to develop an automatic shape optimization procedure where simulations are run on a computer cluster. The user input is limited and the optimization is made automatic by connecting three commercial codes in a closed optimization loop, i.e. AVL Fire (mesh generation and CFD calculations), modeFRONTIER (optimization, process automation and post-processing) and Sculptor (mesh deformation).
