Complicated full of life fabrics - explosive fill and propellants - are a severe know-how for nationwide protection. whereas numerous new promising ideas and formulations have emerged in recent times, the dep. of safety is anxious in regards to the nation's skill to take care of and enhance the information base during this sector. to aid in addressing those matters, places of work inside of DOD requested the NRC to enquire and examine the scope and health and wellbeing of the U.S. R&D efforts in lively fabrics. This document offers that evaluation. It offers a number of findings in regards to the present R&D attempt and proposals aimed toward bettering U.S. functions in constructing new full of life fabrics expertise. This examine reviewed U.S. study and improvement in complex energetics being performed through DoD, the DoE nationwide laboratories, industries, and academia, from an inventory supplied by means of the sponsors. It additionally: reviewed papers and know-how exams of non-U.S. paintings in complicated energetics, assessed vital parameters, resembling validity, viability, and the possibility that every of those fabrics could be produced in volume; pointed out limitations to scale-up and construction, and steered technical ways for addressing strength difficulties; and, advised particular possibilities, innovations, and priorities for presidency sponsorship of applied sciences and production approach improvement.

Air Force. CURRENT GUN PROPELLANTS All those who made presentations on gun propellants noted that over the past 30 years, the basic ingredients in fielded propellants have remained the same. The most important of these ingredients include nitrocellulose, nitroguanidine, nitroglycerin, and other nitrate esters. No propellants using new energetic molecules have been fielded. What has improved during this time period is the processing, formulation, and manufacturing of widely used, legacy molecules.

Effort, much of the work done on thermobarics by others outside the United States focused on direct experimentation, some of which was quite sophisticated and dealt directly, although empirically, with the difficulty in measuring the performance of particular explosive devices. In the aforementioned presentations to the committee, evidence showed that the performance of this type of thermobaric explosive is 7 8 H. Shechter, OSU. 2001.

Studies of thermobaric systems in the West date to about 1988 and were driven primarily by interest from the intelligence communities and by efforts to exploit foreign technology.
