Abstract
Circulation of temperature controlled fluid through cavities in structure stiffening members of hypersonic aerospace vehicles precludes destructive temperature gradients in such members and preserves stress residuals for functional requirements.
Claims18
An aerospace vehicle primary structure thermal conditioning system comprising;
- a quantity of working fluid;
- fluid temperature conditioner equipment;
- fluid transfer means including conduit means;
- one or more primary structure support elements;
- each such support element having an inner and an outer load bearing surface and a fluid flow duct intermediate said surfaces and generally central thereto,
- each duct having an inlet and an outlet port, said ports being coupled to said conduit means,
- temperature sensor means disposed selectively about said conditioning system;
- and
- control means capable of causing said conditioner equipment and transfer means to vary temperature and flow rates of fluid through said support elements.
