Transpirationally Cooled Leading Edges (in Hypersonics)
NASA-Dryden is interested in research on transpirationally cooling the leading
edge of an aircraft wing or other structure that has been developed from a
porous material. Applications may include the space shuttle as it enters the
Earth's atmosphere and Aerogravity Assist craft that briefly enters other planets'
atmospheres. Specific research interests would involve comparing different
coolant and structural materials. Also of interest: determining the amount
and type of coolant used based on current flight conditions or structural materials.
Research involving high Mach numbers (> 20) is also of interest.
