Abstract :
The photogrammetric recession measurement (PRM) technique has been applied in several tests of ablative thermal-protection system materials in the 60-MW arcjet at NASA Ames Research Center. This paper presents selected results from those tests to illustrate the capabilities and limitations of the technique.
