Structures Technology


Book Description

Drawn from early volumes of Aerospace America and its antecedents, this book rescues the insights, concerns, and dreams of dozens of structural engineers for the next generation of aerospace scientists and engineers. Written by eminent individuals in structures, this book provides accessible source material for university-level design courses in aerospace engineering. The first paper in Structures Technology deals with new structures for future aerospace systems and provides a contrast between our current thinking and past technology plans. Succeeding papers are historical reports covering materials and structures, general structures technology, aircraft structures, space structures, and structural dynamics technology. You will also find sections covering structural configurations, thermal protection systems, subsonic aircraft, supersonic and hypersonic vehicles and structures for space systems.




Thermal-structural Combined Loads Design Criteria Study


Book Description

A study was conducted to determine methodology for combining thermal structural loads and assessing the effects of the combined loads on the design of a thermal protection system and a hot structure of a high cross range delta wing space shuttle orbiter vehicle. The study presents guidelines for establishing a basis for predicting thermal and pressure environments and for determining limit and ultimate design loads on the vehicle during reentry. Limit trajectories were determined by using dispersions on a representative nominal mission and system parameters expected during the life of the vehicle. Nine chosen locations on the vehicle surface having TPS or hot structures were examined, and weight sensitivity analyses were performed for each location.
