Research and development efforts for realizing higher performance levels of high energy materials (HEMs) are continued unabated all over the globe. Of late, it is becoming increasingly necessary to ensure that such materials are also eco-friendly. This has provided thrust to research in the area of force multiplying HEMs and compounds free from pollution causing components. Enhancement of the performance necessitates introduction of strained structure or increase in oxygen balance to achieve near stoichiometry. The search for environment friendly molecules is focused on chlorine free propellant compositions and lead free primary explosives. Energetic polymers offer added advantage of partitioning of energy and thus not necessitating the concentration of only solid components (HEMs and metal fuels) in the formulations, to achieve higher performance, thereby leading to improvement in energetics without adversely affecting the processability and mechanical properties. During recent times, research in the area of insensitive explosives has received impetus particularly with the signature of STANAG. This paper gives a review of the all-round advances in the areas of HEMs encompassing oxidizers, high-energy dense materials, insensitive high-energy materials, polymers and plasticizers. Selected formulations based on these materials are also included.

“…Applications of GAP to fuel binder of composite propellants, solid fuel of hybrid rockets, and ducted rockets have been widely investigated [1][2][3][4][5][6][7][8][9] . Because of its self-combustibility, GAP is promising as a solid fuel for the gas generator (GG) type of hybrid rocket system, also called as the gas hybrid rocket 10,11 .…”

Hybrid rockets using Glycidyl Azide Polymer (GAP) as a solid fuel has been studied.Linear burning rate spectrum of GAP was spread with a dilution of polyethylene glycol (PEG), and basically, self combustible mixtures are used for the gas hybrid rocket motor, and non-self combustible mixtures for traditional hybrid motor. Ultrasonic measurement is employed using three sensors especially developed for this use to evaluate the instantaneous surface regression rates in the traditional hybrid motor. Results from three sensors set at the upstream, middle and downstream of 1.3m length motor give indispensable informations for the establishment of the flame model of hybrid motor. Nomenclature C p = sonic speed of fuel grain c = chamber Gox = mass flux of oxygen gas O/F = oxidizer to fuel ratio rb = surface regression rate of solid fuel Pc = chamber pressure ox = oxygen

Hybrid rockets that use glycidyl azide polymer (GAP) as a solid fuel were studied. The linear burning rate spectrum of GAP was broadened when it was diluted it with polyethylene glycol (PEG). Self-combustible mixtures were used for the gas hybrid rocket motor; non-self-combustible mixtures were used for the traditional hybrid motor. Both were tested as functions of various experimental parameters, and the results of the traditional hybrid rocket are summarized in this paper. In particular, the fuel regression rates of GAP50PEG50 and GAP60PEG40 fuels were investigated, and the results indicate that the fuel regression rate of the fuel with high GAP content showed pressure dependability. Simultaneous measurements of the surface regression rate, which has attracted great interest, were conducted using ultrasonics in a special chamber, the results for the instantaneous surface regression rate during combustion were obtained. The obtained results are presented, and on the basis of experimental observations, a flame model of the traditional hybrid motor is discussed.
