Summary

The COMBAT EDGE/ATAGS (CE/ATAGS) ensemble offers superior G-protection compared to the standard anti-G ensemble, significantly reducing G-induced loss of consciousness (G-LOC) and aircrew fatigue during simulated combat sorties.

Area of Science:

  • Aerospace Medicine
  • Human Factors Engineering
  • Physiological Stress Response

Background:

  • Advancements in aviation necessitate the evaluation of new G-protection equipment for aircrew.
  • Existing anti-G ensembles require rigorous testing to ensure optimal performance under high-G conditions.

Purpose of the Study:

  • To compare the effectiveness of the COMBAT EDGE/ATAGS (CE/ATAGS) ensemble against the standard CSU-13 B/P anti-G ensemble (STD).
  • To assess the impact of these ensembles on aircrew tolerance to multiple simulated aerial combat sorties.

Main Methods:

  • Fifteen subjects were exposed to three centrifuge-based simulated aerial combat sorties.
  • Subjects wore either the STD or CE/ATAGS ensemble.
  • Physiological and subjective responses, including heart rate, peripheral light loss (PLL), effort, fatigue, and recovery time, were measured.

Main Results:

  • The CE/ATAGS ensemble resulted in zero G-induced loss of consciousness (G-LOC) incidents, compared to four with the STD ensemble.
  • CE/ATAGS significantly reduced heart rate, peripheral light loss, subjective effort, and fatigue levels.
  • Reported recovery times were nearly halved when using the CE/ATAGS ensemble.

Conclusions:

  • The CE/ATAGS ensemble provides significantly enhanced G-protection compared to the standard ensemble.
  • The absence of G-LOC and reduced physiological strain with CE/ATAGS indicate improved aircrew G-tolerance.
  • This enhanced protection has significant operational value for increasing sortie generation capability and aircrew performance.
