USAF 80s-today



During the 80s modifications continued to be made as advances in aircrew protective helmet technology led to new products, incorporating both new materials and improved fabrication techniques. These modifications included communication upgrades, visor and external shell design, more comfortable internal liner and updated oxygen breathing mask systems. Advanced research on new Tactical life support systems led to a new generation of helmets for use in high performace aircraft and for Nuclear Biological Chemical protection. During the early 90s the USAF standard flight helmet HGU-55/P was modified to incorporate the COMBAT EDGE system designed to improve high performance fighter pilot tolerance to high G maneuvers.
At the beginning of 2000 the new Joint Helmet-Mounted Cueing System (JHMCS) was introduced into service to be operatively flight tested on F-15 Eagle and F-16 Fighting Falcon.

HGU-48/P

The HGU-48/P made by Gentex was in the early version based on modified HGU-22/P shell (PRK-37/P was used in the later version). The shell was trimmed by a life support technician at Nellis Air Force Base to appease pilots complaining about the poor visibility and weight of the HGU-26/P. internal custom fit liner was normally used and dark grey leather sections were glued to the outside of the shell to provide a resting surface for the visor in the stowed positon and prevent scarring of the helmet surface when raising or lowering visor. Snap-on visor assembly attaches to the outside shell by snap fasteners on each side was utilized. Cast retainers was used to secure the MBU-5/P or MBU-12/P oxygen masks.

HGU-51/P

The HGU-51/P Integrated Chemical Defense Helmet System (ICDS) made by Gentex was produced in limited numbers mainly for F-111 and F-4 pilots in the late 70s early 80s. The system consisted of a lightweight HGU-51/P Kevlar flight helmet that featured internal cooling and ventillation systems, an internal oxygen delivery system, mounts for the EDU-2/P Nuclear Flash Protection Goggles and internal drinking facility. Worn with the helmet was a heavily modified Gentex MBU-12/P Oxygen Mask with dual valves, drinking straw, elctret microphone and TLSS style composite bayonets. The mask used a small duct that was integrated into the left side bayonet and which was fed oxygen by the helmet's internal oxygen delivery system which was supplied by a rear entry hose. Numerous visors were also offered including Clear and Neutral along with Laser Visors or the PLZT Nuclear Flash Goggles. The Visors aere designes so that they could be worn over the nuclear flash goggles as well. The twin rear entry helmet hoses connected to two more hoses that terminated in alarge friction emergency disconnect which in turn, connected to a seat mounted CRU-84/A Oxygen Regulator. Between two of the hoses was a metal C2A1 filter holder to help filter the Oxygen that was being fed to the Pilots oxygen mask. This cannister and associated hoses was secured via a quick release. A face/neck skirt cover was also used with this helmet.

HGU-53/P

The USAF HGU-53/P helmet made by Gentex was the first U.S. hemet designed with continuous locking rotary visor system that has been qualified at 600 knots equivalent airspeed (KEAS). The hemet shell is made of a light weight kevlar material, and its profile differs from the previous helmets with a reduction in external dimension for improved canopy clearance. The HGU-53/P is utilized with USAF standard MBU-12/P. The HGU-53/P retrofitted with COMBAT EDGE system use the MBU-20/P low profile oxygen mask.

HGU-55/P ; HGU-55/E

The HGU-55/P helmet assembly is made of fiberglass fabric molded with epoxy resin. It is equipped with energy-absorbing styrofoam liner but a custom fitted Thermoplastic liner (TPL) was also available. The helmet is equipped with a single snap-on visor that eliminates the visor housing for reduced weight and a lower profile but it is capable of accepting the PRU-36/P dual visor assembly or a single visor assembly with a housing. The HGU-55/P integrate the H-154A/AIC Headset and lightweight oxygen mask receiver kit.This helmet was normaly utilized with USAF standard MBU-5/P, MBU-12/P oxygen masks.
The HGU-55/E is identical to the standard HGU-55 except that a protective visor assembly replaces the bungee visor. Its protective visor housing allows easy movement of the impact-resistant polycarbonate lens and locks the lens securely up or down.

Tactical Life Support System (TLSS)

The USAF Tactical Life Support System (TLSS) is the precursor to the Combined Advanced Technology Enhanced Design G-Ensemble (COMBAT EDGE) and it was the first US Air Force Advanced Development life support program. The TLSS program had a wide range of research objectives that included nuclear, biological, chemical (NBC) protection, advanced anti-G protection, moderate high-altitude protection, anti-flash eye protection, aircrew cooling and personal conditioning, and on-board oxygen generation. Items of the system included an entirely new and light-weight helmets and oxygen mask system, G-suit and counter-pressure vest, nuclear flash protection goggles and NBC protective garment systems. The TLSS never reached fully operational status, however several elements tested in this program have been incorporated into the present COMBAT EDGE system.

HGU-55/P (Combat Edge)

The Combined Advanced Technology Enhanced Design G-Ensemble (COMBAT EDGE) is a pressure breating for G (PBG) system that improves a high-performance fighter pilot's tolerance to high-G maneuvers and is effective in preventing G- induced loss of consciousness (GLOC). Items of the system included, G-suit and Counter-pressure vest, Integrated Terminal Block pressure regulator, modified HGU-55/P with KMU-511/P kit and MBU-20/P low profile oxygen mask.
The complete Helmet Modification Kit KMU-511/P, designed to be easily retrofitted into standard HGU-55/P, consist of a urethane-coated nylon bladder, PBG feed tube and quick-disconnect connector, specially contoured polycarbonate visor, hook and pile fasteners. This system provides automatic mask tensioning during PBG to keep the mask in positon under pressure, but only at high G so the pilot does not have to wear the mask uncomfortably tight at all time.

AIR COMBAT SYSTEM

The Gentex Air Combat System or Advanced Tactical Life Support System (ATLSS) dual visor helmet is part of a fully integrated support system for tactical aircraft similar to the COMBAT EDGE system. The helmet utilizes an adjustable rotary visor mechanism. The left side mechanism controls the inner clear visor and the right side mechanism controls the outer sunshade visor. The helmet shell is constructed from an advanced lighweight Kevlar. The Air Combat System includes a modified MBU-20/P oxygen mask incorporating lighweight bayonets and receivers which provide a direct pneumatic coupling for automatic mask tensioning. the oxygen inlet hose is fitted to the right side of thefacemask, instead of the left. The other elements of the ATLSS system are the two-piece combined flight suit/anti-G, chest counter pressure garment and chest-mounted regulator.

Rare Prototype of an Air Combat System (ACS) early ATLSS type flight helmet. This is one of the early attempts by Gentex Corp to what would later become the Combat Edge series helmets, the bladder at the rear is actually integrated into the edgeroll assembly via ducting from the mask as in the early HGU-35 of the 1970s . The mask is integrated into the edgeroll and the bladder system is inflated by the supply tube on the left side of the main hose. The shell is made of carbon fiber composite and the edgeroll is black leather and similar to the HGU-55. This helmet was a prototype built by Gentex and was used in flight testing on the YF-22 and YF-23. (Surplusagent)

NORTHROP McDONNEL DOUGLAS AFT-23 EXPERIMENTAL HELMET

This unusual integrated full face helmet (probably also partial pressure helmet) was verly likely an house design from Northrop/MD to be tested in the 1990 on the YF-23 technology demonstrator fighter aircraft. It was probably also designed for an integrated oxygen/NBC life support system.


Very rare Northrop/MD experimental full face helmet designed to be tested on the YF-23 Black Widow in the 1990.
The helmet seems to have the tinted visor internally. The track for the visor is located externally on the rear top and the visor knob is very similar to the one used onthe AH-64 Apache IHADSS visor housings.



The helmet is equiped with standard H-154 ear cups setup and and lateral quick disconnect oxygen/pressure hose and communication cable
HGU-86/P

The HGU-86/P helmet is developed by the UK firm Helmets, Inc., in cooperation with Boeing and Gentex. This helmet has improved retention proven for ejections in excess of 600 knots, minimizing lift forces, maximum noise attenuationand universal sizing ergonometry refinements, light weight, enhanced peripheral field of vision, an improved earcup tensioning system, active PRU-57 Noise Reduction circuitry, and improved mask retention and adjustment receivers. The HGU-86/P has been designed in combination with the new (low profile, low moment of mass, and excellent visibility) MBU-22/P oxygen mask, which has an automatic mask face-seal tensioning bladder on the front of the mask and its separated inhalation and exhalation valves achieve a greatly lowered resistence to breathing. The HGU-86/P plus MBU-22/P system has been flight tested on USAF F-22 Raptor advanced fighter as well as the X-35 experimental fighter.

JHMCS

The Joint Helmet-Mounted Cueing System (JHMCS) is intended to be used with the AIM-9X Sidewinder missile. This highly accurate cueing system provides pilots with "first look, First shot" high off-boresight weapons engagement capabilities. JHMCS enable the pilot to accurately direct (cue) the missile against enemy aircraft while performing high-G aircraft maneuvers.
The pilot needs only to point his head at the target and weapons will be directed to where the pilot is looking. The system can also be employed to accurately cue the pilot to ground target. A later version of the JHMCS helmet has been updated with a new helmet mounted queing system which has targeting technology that projects holographic data on the inside right of the visor in the form of a container, or que and allows pilots to continually survey and distinguish between friendly and enemy air and ground targets. The helmet also holsters a camera and a projector that assist pilots with air operations. The camera is embedded in the helmet and sits over the left eye, allowing servicemembers on the ground to see exactly what the pilot sees. The advantage of having this new system is the holographic image that is displayed wherever the pilot looks This helmet is utilized by US Air Force F-15 and F-16 pilots with Oxygen mask MBU-20/P.
The JHMCS is also used with the new Night Vision Cueing and Display (NVCD) This system incorporates the same symbology - including airspeed and altitude, heading, and where the aircraft sensors are looking - shown in the JHMCS into a four-tube night vision goggle. The only difference is that it is injected into a tube on the goggles overlaying the night scene. There is also a camera mounted on the goggle that records everything, which serves as a useful post-flight debrief tool. The two outer tubes can be removed creating a two-tube version, known as Mini-QuadEye. Configuring the JHMCS for the Mini-QuadEye is easy. The goggles simply snap onto the front of the helmet and can be modified for individual preferences.

MODULAR AIRCREW COMMON HELMET

The Gentex Modular Aircrew Common Helmet (MACH) system is a two part concept developped from the experimental IMH (Integrated Mission Helmet). It consist of an inner "Life Support Module" (LSM) and "Outer Mission Module" (OMM). Each pilot will be issued a custom fitted LSM which will be compatible with existing aircrew oxygen mask. Outer Mission Modules will then be configured to accomodate all current and future helmet mounted equipment and displays. The goal of this system is to reduce the current inventory of 27 helmets and helmet configuration down to a single design.
The MACH system will draw upon Gentex Corporation's capability to integrate a number of life support, display and communications capabilities into a single aircrew helmet system. These include the ability to merge the protective requirements of both rotary-wing and fixed-wing aviators into a common helmet platform as well the ability to integrate a diversity of communications equipment and head mounted electro-optical elements into a single design. Integrating all of these capabilities into a single design will enhance the ability of US aviators to perform in a variety of combat situations, lighting environments and environmental conditions. (Gentex)
SCORPION HELMET-MOUNTED CUEING SYSTEM

the Gentex/Raytheon Scorpion helmet-mounted cueing system. The Scorpion has been developed by GentexVisionix, with systems integration provided by Raytheon. It is a monocle-based system that has both fixed- and rotary-wing applications, with minimal airframe intrusion, requiring just a single, small interface control unit and one magnetic sensor mounted in the cockpit. Scorpion provides the pilot with a variety of data in the display, from HUD-style flight information to colour imagery from sensors. The display can be set to remain forward- facing, or can track as the pilot moves his or her head. Advanced processing provides a fast refresh rate, in turn providing seamless imagery as the head moves, with no time lag.
Among the capabilities of the system, which is fully integrated with the aircraftís avionics, is the ability to provide GPS co-ordinates of designated points for targeting or handing off to other platforms. Using a monocle system over more expensive full-visor projection has several advantages, both in operational terms and in cost. The display can be swung out of the way if it is not required, and its small size imposes no extra weight burden on the pilotís head. The system fits on to the standard Gentex helmet, and is interchangeable between helmets, so that fewer have to be purchased to equip a unit. Another advantage is that it works with standard night-vision goggles, which can be swung down in front of the monocle display.
Scorpion has already found two applications in the US Air Force, and it is being proposed to equip the Air National Guardís A-10 and F-16 fleets. It has also aroused much interest in the export market. The system is being demonstrated on th Raytheon stand (Hall 1, C154). (Gentex)

LifeBEAM Monitoring Helmet

The Pilots & Astronauts monitoring helmet was developed with the cooperation of the Israeli Air Force (IAF) as the first product in the world to monitor pilots during flight.
LifeBEAMís optical technology is integrated into Fighter Pilot helmets and measures blood flow (perfusion), pulse rate, and SpO2. LifeBEAMís state of the art algorithms are integrating several sources of information: pilotís physiology, aircraftís physics (G-forces, velocity, altitude & positioning) and pilotís head & body postures. Based on the above data and by using machine learning & neural network methods, the system automatically detects life-threatening situations, such as Hypoxia, A-LOC and G-LOC in real-time.
When the system identifies a development of a dangerous situation, it provides an immediate alert to both air & ground crew. The system also enables integration with aircraftís systems such as automatic pilot & flight debriefing tools. The system was evaluated during F-16 flights, centrifuge trainings, NASAís training facilities and in hypobaric chambers.
