Gap Filler Response in Arc Jet Testing<br />
Mars Science Laboratory<br />
• Gap response dependent upon heating conditions<br />
– High heating – gaps at any angle with the flowfield experienced recession<br />
comparable to the surrounding PICA<br />
– Low heating – gaps at low angles with the flowfield protruded<br />
