This book was released on 2005 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: [Author's abstract, shortened by cataloger] The restraint system is a major element in providing occupant safety in modern day military aircraft's. The United States Air Force (USAF) has conducted numerous dynamic tests in order to provide a better restraint system for its pilots and passengers. Various proposals have been made in recent years and been discarded. One such restraint system was the USAF conventional double shoulder strap and lap strap configuration or also called a 5 point restraint system. Although, it shows from the dynamic tests conducted by the USAF at Air Force Aerospace Medical Research Laboratory (AFAMRL) that the 5 point restraint system provides a secured method of restraining the occupant to the aircraft seat, there are still certain kinds of limitations. One such limitation is "submarining" of the lower torso of the occupant which may cause severe injuries to the occupant. In order to avoid that a Negative G strap or a tie down belt strap is attached as an additional restraint to the S point restraint system. A test program was conducted to assess the influence of a negative G strap on restraint dynamics and human impact response.

This book was released on 1983 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: A test program to assess the influence of a negative G strap on restraint dynamics and human impact response was conducted. Research objectives were to evaluate the effects on human impact response of negative G strap incorporation into restraint systems; To evaluate human impact response in the PCU-15/P torso harness and lap belt configuration compared to such response in a conventional double shoulder strap and lap belt configuration, and to obtain human impact response data for use in present and future mathematical modeling efforts which are intended to predict human inertial response to impact.

This book was released on 2003 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has long been known that the proper use of safety restraining devices in aircraft can greatly reduce the risk of serious injury and even fatality in the event of a crash. The use of shoulder belts with lap belts could reduce major injuries by more than 85% and fatalities by 20% 3. Numerous studies have also linked the improper use of safety belts and shoulder harnesses to injuries in cases of rapid deceleration. Studies and investigations on fatal aircraft accidents led the Federal Aviation Administration (FAA) to require all new aircraft to have shoulder restraints installed in 1969. Head, neck, abdominal and chest trauma are the most critical to life. Even injury to the upper extremities can result in unnecessary loss of life if the individual is unable to evacuate the aircraft in an emergency, such as a post-crash fire or to avoid drowning. Roughly one third of the deaths in aviation accidents in the 1950's and 60's might have been avoided if shoulder restraints had been used 8. The question arises as to whether merely having restraints is good enough or if there is a best way to configure the restraints. It has been shown that using a double shoulder harness system with lap belts is preferred over a single diagonal shoulder belt and a 3-point belt system with a single shoulder belt and lap belts 6,7. The double harness prevents the torso from twisting out and around the single shoulder belt, significantly reducing the risk of injury. The distribution of applied loads to two belts is also greater than the same loads applied to a single belt, causing less stretching of the belt and greater restricted forward movement 9.
Book Synopsis MPES Negative G Restraint Strap Design Options by : Thomas J. Zenobi
Download or read book MPES Negative G Restraint Strap Design Options written by Thomas J. Zenobi and published by . This book was released on 1981 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preliminary investigation shows that the negative G restraint configurations are viable design approaches. The restraint systems will be fabricated and incorporated into MPES. Human subjects will be used for evaluation of the negative G restraint. Areas of concern which will be studied are: crewman comfort; ease of donning/adjusting the restraint, and restraint release for man/seat separation. For measuring effectiveness of the restraint under the negative G environment, the seat/man configuration will be suspended upside-down (simulating a -1G environment) and measurements and observations will be noted. The NADC centrifuge also looms as a possible test bed for testing the negative G restraint under a variety of negative G profiles. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: "The ongoing COVID-19 pandemic marks the most significant, singular global disruption since World War II, with health, economic, political, and security implications that will ripple for years to come." -Global Trends 2040 (2021) Global Trends 2040-A More Contested World (2021), released by the US National Intelligence Council, is the latest report in its series of reports starting in 1997 about megatrends and the world's future. This report, strongly influenced by the COVID-19 pandemic, paints a bleak picture of the future and describes a contested, fragmented and turbulent world. It specifically discusses the four main trends that will shape tomorrow's world: - Demographics-by 2040, 1.4 billion people will be added mostly in Africa and South Asia. - Economics-increased government debt and concentrated economic power will escalate problems for the poor and middleclass. - Climate-a hotter world will increase water, food, and health insecurity. - Technology-the emergence of new technologies could both solve and cause problems for human life. Students of trends, policymakers, entrepreneurs, academics, journalists and anyone eager for a glimpse into the next decades, will find this report, with colored graphs, essential reading.
