F-22 Raptor maintainers had a problem. Stuffy coveralls were making their work on the aircraft's low-observable coatings distractingly hot and humid during the summer months.
So researchers from Headquarters Air Combat Command's science and technology department stepped in to develop new cooling suits to help keep airmen comfortable when working on flight lines.
Our science and technology team at HQ ACC heard about the challenging operating conditions that our low-observable maintenance airmen have to work under,Dr. John Matyjas, HQ ACC chief scientist, said in a statement. It's hot, strenuous, and requires particular focus on the task at hand.
Matyjas toured the 1st Fighter Wing, then offered advice. We listened and began looking for innovative portable cooling solutions to meet the demand, he said.
