Abstract:

Physical compatibility assessments of the Aviator Night Vision Imaging Systems ANVIS were completed on subjects wearing the HGU-56P. Data were obtained from 172 subjects participating in a helmet fitting study. Subjects were fitted with the HGU-56P developer- recommended helmet size based on head length and up to two additional sizes smaller and larger. On several subjects, compatibility assessments included the M-43A1, type 2, protective mask. Additional measurements of minimum ANVIS eye clearance using rigid head forms were taken to compare with similar data obtained from the subjects. Our results indicate 1 most subjects achieved acceptable ANVIS mechanical compatability and acceptable eye relief while wearing the HGU-56P, 2 placement of the ANVIS mount higher on the visor cover will increase compatibility, 3 fitting one size larger than the developer-helmet size probably will be required to achieve acceptable and comfortable fit while wearing the protective mask.
