Considerations concerning a thermal joint for a deployable or steerable battery radiator for the Columbus Polar Platform

Different concepts for a moveable thermal joint are described and discussed with respect to the applicability in a dedicated deployable or steerable heat pipe radiator system to handle the waste heat of the NiH batteries of the Polar Platform. Concepts which are identified as possible candidates for near-term deployable radiator development are:...

Limitations in variable conductance heat pipe performance and control predicted by the current steady-state model developed at NLR

A uniaxial model for the transient performance of gas-loaded variable conductance heat pipes is being developed, partly under contract with the Netherlands Agency for Aerospace Programs NIVR. The model has to be easily implementable in existing spacecraft thermal analyzer computer programs. So far, a steady-state version of the model is...

A theoretical investigation of gas conduction effects on multilayer insulation performance

The thermal performance of multilayer insulation hlankets depends on three (interacting) modes of energy transfer: radiation between the radiation shields, gas conduction in the residual interstitial gas and solid conduction via the contacting interfaces. The contribution of the gas conduction depends on the interstitial gas and its pressure,...

Induction heating of mastic containing conductive fibers and fillers

The objective of this research is to examine the induction heating of mastic through the addition of electrically conductive fillers and fibers (graphite and steel wool), and to prove that this material can be healed with induction energy. The effect of fibers content, sand–bitumen ratio and the combination of fillers and fibers on the induction...

Crack repair of asphalt concrete with induction energy

It is well known that the healing rates of asphalt courses increase with the temperature. A new method, induction heating, is used in this paper to increase the lifetime of asphalt concrete pavements. Mastic will be first made electrically conductive by the addition of conductive fibers. Then it will be heated via induction energy. This will...
