The results of a test program conducted to determine the physiological effects of personnel armor on aircrew members exposed to an aircraft crash environment are presented. Emphasis was placed on the effects of armor as worn by air crews in current military operations. The program was divided into two major tasks. The first included a literature search to obtain design data on human injury simulation techniques, a conference to obtain information from a group of combat-experienced US Army medical helicopter crewmen on the impact behavior of the armor in observed accidents, and modifications to anthropomorphic dummies to effect recordings of mechanical injuries to vital body areas. The second task consisted of three types of dynamic tests vertical drop tower tests, horizontal accelerator tests, and a full-scale helicopter crash test. Test results indicated that the potentially dangerous effects of the armor during a crash situation are relatively few. The most serious problem appears to be the possible collapse of the trachea following an impact of the upper edge of the armor with the front of the neck.
