modeFRONTIER Implementation Challenges and Benefits at IAI

Mon, 12/05/2014 - 10:00 - 10:30

Nowadays Multidisciplinary Design Optimization (MDO) is considered a common practice for complex engineering design problems. These design cases are characterized with high number of design variables and non-trivial design space. It contains multiple contradicting cost functions (Multi-Goal design problems) and various constraints, which are product of various discipline simulations.

Usage of MDO enables the solution of these design cases, while integrating different disciplines into a synergetic comprehensive design environment. Furthermore, using numerical optimization schemes, a methodical study of the complex design space is accomplished. Thus, the global optimum is searched while avoiding local minima areas. 

A review of MDO principles will be given with emphasis on the implementation challenges and the benefits of using a state-of-the-art design framework, which at IAI is ESTECO modeFrontier.

Several design research cases will be discussed, such as: 

  1. Design of rotating wing which searches for the optimum compromis between different flight regimes.
  2. Design case research of auxiliary power using (APU) chamber, which uses various disciplines such as heat transfer simulation, aerodynamic drag penalty, and internal flow models.
  3. Solar unmanned aerial vehicle (UAV) conceptual design, which focuses on the energy balance between solar radiation, battery pack, and the airvehicle required operating power.
