Nosetip Cooling Technology (NCT) Program: Investigation of Discrete Injection Cooling
Abstract
The objective of the Nosetip Cooling Program (NCT) has been to develop engineering methods for designing discrete injection hardware based on a fundamental understanding of the complex mechanisms associated with heat and mass transfer over and within slotted surfaces. As a result, a series of experimental programs have been performed to identify the critical aerothermodynamic parameters associated with discrete injection transpiration cooling systems. The major finding of the NCT Program has been the identification and quantification of the effective surface roughness due to slotted surfaces. This roughness gives rise to augmented heating levels, both locally and downstream, for injection flow rates of interest.
