摘要

Aerospace systems require a fusion of concepts and have tight coupling between several disciplines like propulsion, structures, control, aerodynamics etc. They also have to take into account the manufacturability, reliability and maintainability. This special issue is on "Aerospace Systems" being brought out with the main aim of focusing attention on some of the complex issues involved in the design and analysis of systems like aircraft, launch vehicles and spacecraft. There are altogether nine papers in this issue, in which five papers address specifically the areas of propulsion, structures, control and aerodynamics respectively. Aerospace systems are essentially multidisciplinary, highly complex, with several technologies interacting together and therefore preventing each one of them from being handled separately. The field of Multidisciplinary Design Optimization (MDO) provides answers on how to integrate them into the design process, while reducing the design cycles. One paper on MDO specifically brings out these issues. There are two papers which address the technologies and challenges in unmanned aircraft and spacecraft systems.
