Exploring Preliminarily Four Critical Technologies of Multidisciplinary Design Optimization (MDO) of Radome

Aim. As MDO of radome is extremely difficult but very much needed, we began exploring it, making progress slowly. Section 1 of the full paper proposes the MDO of radome. Fig.1 in section 2 gives the schematic of the main disciplines involved in MDO of radome. Subsection 3.1 analyzes the first critical technology, which is parameterization modeling and grid generation including grid data transmission among different disciplines; the interpolation method is recommended for use in data transmission. Subsection 3.2 analyzes the second critical technology, which is approximation; the response surface method is advised. Subsection 3.3 analyzes the third critical technology: MDO platform. Subsection 3.4 analyzes the fourth critical technology, which is optimization strategy; it provides the flow chart of multidisciplinary feasible method of radome MDO.
