HGU-68P U.S. Navy Tactical Aircrew Helmet
The HGU-68/P Tactical Aircrew (TACAIR) helmet is designed by Gentex to meet the requirements of the U.S. Navy and U.S. Marine Corps in today’s High-G environment.
The TACAIR helmet is equipped with a single visor system qualified at 600 KEAS (knots equivalent airspeed) in accordance with MIL-H-85047A. The TACAIR helmet integrates with the latest advances in technology to provide improved comfort, stability, retention and protection for military aircrew personnel. The helmet frontal opening is cut back in the temple regions to provide maximum peripheral vision.
The helmet shell is a rigid composite made of pressure molded, laminated graphite and nylon, Graphlon®. The shell is dark aircraft green using a polyurethane paint system. A black leather edgeroll covers a soft foam core around the entire periphery of the shell. Pile fastener fabric is cemented inside the earcup regions to attach the earcups.
A styrofoam energy absorbing liner is the primary impact attenuation medium. A preformed Thermoplastic Liner (TPL®) provides an easily fitted, lightweight, comfortable custom lining.
The TPL consists of multiple layers of thermoplastic which have been formed to create protrusions that partially collapse when heated to conform to the contour of the head. The layers are lined with a removable/launderable foam and cotton polyester cover.
An optional helmet comfort liner, the X Liner ®, is available.
Integrated Chin/Nape Strap
The chin/nape strap is a unique, one-piece assembly threaded through the helmet and adjusts at the chin strap. Cross straps threaded through the nape strap pad adjust simultaneously with the chin strap to provide a snug yet comfortable fit ensuring helmet stability and retention. The chin/nape assembly is made of nylon webbing and features chin and nape strap pads covered with leather. Sliding clamps are installed on the left and right nape straps at the shell slots to allow individual adjustment of the nape straps if desired.
600 Knot Lightweight Visor
A single visor system provides the lowest possible profile to prevent canopy interference. The visor lock is located left of center to further enhance this low profile. A latch system is incorporated at the end of the visor lock guide to allow quick change of visors before flight to meet specific mission requirements. The neutral gray, abrasion resistant, polycarbonate visor is standard equipment. Clear, gradient, high contrast, and laser attenuating visors are available as spares. A leather visor cover is provided. The track visor system may be removed and replaced with a bungee style visor to accommodate an ANVIS Night Vision Goggles mount.
The communications consist of the CX-4708A/AIC cord (modified with extended length pins), H-87B/U earphones, lightweight tapered earcups, custom leather earpads, earphone holders, and earcup spacer pads. The leather earpads enhance helmet fit providing the “glove fit” feel.
Oxygen Mask Bayonet Receivers
Lightweight bayonet receivers are provided to reduce weight and profile. They have been blackened to blend with color scheme and consist of jaw/receiver assembly, mounting screws, lock washers, and backplates. The receivers are individually fitted during the helmet fitting process.
Minimum performance requirements
Impact Energy Attenuation
The helmet shell/styrofoam liner/TPL limits the acceleration imparted to a test headform to 400G at an input energy of approximately 35 foot pounds.
The helmet assembly is designed not to rise, loosen, or show evidence of material failure when exposed to 600 KEAS (knot equivalent airspeed) +/– 20
KEAS at the altitudes:
- Head On/Head Up
- 45° Starboard/Head Up
- Head On/Tilted 45° Aft
- Rotated 45° Port/Tilted 45° Aft
