The HGU-55/P helmet shell is intended to provide head
protection during in-flight buffeting and emergencies such as ejection,
bailout, or crash landings.
It is delivered with leather edgeroll. Leather buffers
prevent the visor from scratching the helmet shell. Pile fastener inside the
shell holds the earcups in place. Portions of the pile fastener are left
detached to allow installation of the oxygen mask bayonet receivers. We deliver the helmet with either
Kevlar or Fibreglass shells. All shells and comm kits are US MIL SPEC .
Memory energy-absorbing Liner. The soft foam energy-absorbing liner absorbs and reduces impact forces. The liner is held
snugly to the inside of the helmet shell by the edgeroll and we deliver the helmet with Memory Liner Oregon Aero ,Zeta Liner® or just standard Thermoplastic Liner (TPL®)
The integrated
chin/nape assembly, when properly adjusted, stabilizes the helmet during
routine flight, bailout, and other high-stress conditions. Tightening the chin
strap also tightens the fit of the nape pad. Metal clamps help keep the
adjusted chin strap in place. Headset. The headset allows the aircrew member to
communicate both inside and outside the aircraft. It also helps protect the
ears from hearing loss due to long-term exposure to noise.
Included are two earcups either standard or Oregon Aero hush kit type two 19-ohm H-143/ AIC earphones, and a CX-4708A/AIC cable.
The earphones are housed inside the earcups and are connected to the cable.
