Book Description
The impact protection provided by a commercial motorcycle helmet is evaluated in this report. The motorcycle helmet utilizes an expanded plastic foam liner of 12 mm thickness, which is less than that used in most motorcycle helmets made in this country today. The thickness of the foam is identical to that used in the US Army Aviator's standard Sound Protective Helmet No. 4 (SPH- 4). The impact protection provided by the commercial helmet is compared to the protection provided by the SPH-4 aviator helmet.

Book Description
Injury data was obtained from the U.S. Safety Center for the occupants of U.S. Army aircraft who were wearing aviator helmets when involved in duty-related aircraft accidents from the period beginning in June 1982 and ending in October 1987. The injury data was correlated with the physical condition of the helmets involved which had been obtained by the U.S. Army Aeromedical Research Laboratory under the Aviation Life Support Equipment Retrieval Program. The helmet performance was evaluated with regard to current injury prevention capabilities and potential improvements for future helmet designs. All helmets involved were involved in aircraft accidents except one SPH-4 which had been damaged by small arms fire. Keywords: Head injury, Crushable earcups, Chinstrap, Facial injury, Energy attenuation, Helmet visor, Foam compression, Protective clothing. (sdw).

Book Description
Impact protection during a crash is one of the primary functions of a flight helmet. In order for the helmet to provide effective impact protection, the helmet must remain firmly secured on the head for the entire duration of the crash sequence. If the helmet is displaced on the head or comes off during the crash sequence, cranial exposure and subsequent head injury can occur. Previous research at USAARL has shown the retention assembly of the SPH-4 flight helmet often allows excessive helmet rotation or even helmet loss to occur during a crash. This report describes the construction and testing of a new SPH-4 retention assembly, the USAARL yoke harness, which will alleviate the helmet rotation/helmet loss problem. The load versus elongation under load and comfort of the USAARL yoke harness was compared to that of the currently used standard retention harness. The USAARL yoke harness was stronger, and stretched less under load than the standard retention harness. Comfort testing of the USAARL yoke harness showed the majority (72 percent) of those questioned preferred the USAARL yoke harness over the standard harness. Keywords: Impact protection, Helmet, Yoke harness, Retention harness, Retention assembly. (sdw).

Book Description
The incorporation of technology into aviation has been exponential. Advancements in microelectronics, stealth technology, engine design, and electronic sensors and displays have converted simple aircraft into formidable flying machines. In this book, recognised experts in aviation helmet-mounted displays (HMDs) summarise 25 years of knowledge and experience in the area of HMD visual, acoustic, and biodynamic performance, and user interface issues such as sizing, fitting, and emergency egress.

Book Description
The effectiveness of the Army's SPH-4 flight helmet in reducing the severity of head injuries sustained during helicopter accidents was evaluated, using the accident data base at the U.S. Army Safety Center (USASC), Fort Rucker, Alabama. Analysis was restricted to severe (Class A) 1972-1988 accidents that were at least partially survivable, using USASC criteria. Occupants who were not wearing a protective helmet were significantly more likely to sustain severe and fatal head injuries than occupants wearing the SPH-4 (RR=3.8 and 6.3, respectively). Unhelmeted non-cockpit occupants faced higher risks (RR=5. 3 and 7.5). All personnel regularly participating in helicopter flight, civilian or military, should be equipped with protective headgear.
