- Abstract
- The three modes of heat transfer, convection, radiation and conduction, are discussed with respect to their roles in thermal protection systems. Fire resistant flight clothing developments demonstrate that double-layer fabrics with air spacing are highly successful in protecting from flame contact. Comparisons of Project White with green fabrics illustrate that in radiation heating the effect of direct transmittance may override the benefits of air spacing, while absorption of heat by materials of low conductivity may compensate for reflectance deficiencies. Finally, the diver's wet suit exemplifies the point that conductive heat transfer alterations are entirely dependent upon insulation thickness.
