A Laboratory Comparison of Three Methods of Personal Conditioning

Abstract : Twelve subjects were used to obtain comparative data between a water cooled, a convective air cooled and a reverse flow air cooled personal conditioning system during laboratory simulations of a typical operational sortie in a hot climate. The results generally favoured the water cooled system on physiological, behavioural and subjective grounds. The results of this laboratory trial may not necessarily transfer to realistic operating conditions and further field testing both in flight and using appropriate ground equipment will be required before it can be shown whether these advantages can be realised.
