Studies on the Internal Ballistics of Composite Solid Rocket Propellants Incorporating Nano-Structured Catalysts
This paper deals with the analysis of burn rate using various catalysts of Iron Oxide and determining which gives the higher burn rate with low pressure variation. The Ammonium Perchlorate (AP) was obtained and ground into fine powder with the particle size ranging from 63 to 125 μm. The propellant strands were prepared with proportions by mixing AP with the binder (Hydroxyl Terminated Polybuta...
متن کاملElectrospun Nitrocellulose and Composite Nanofibers
Electrospinning was applied to nitrocellulose (NC) solutions in DMF, DMSO and Ethyl methyl keton to obtain NC nanofibers. Electrospraying process was observed when DMF was used as solvent. In comparison to NC/DMF, NC/DMSO solution resulted in the formation of a coating film as indicate by SEM. Two different electrospun nanofibers, smooth nanofibers wit...
متن کاملTi-alloys: Potential nano-modifier for Rocket Propellants
Composite solid propellants were prepared with and without nano-alloys (Ti-Co, Ti-Ni, Ti-Zn), where nano-alloys used as catalyst. These nano-alloys are prepared by hydrazine reduction method. Catalytic properties of these nanomaterials were measured on Ammonium perchorate/hydroxyterminatedpolybutadiene propellant by thermogravimetery analysis and differential thermal analysis. Both experimental...
متن کاملHigh-pressure Burning Rate Studies of Solid Rocket Propellants
Increased rocket motor performance is a major driver in the development of solid rocket propellant formulations for chemical propulsion systems. The use of increased operating pressure is an option to improve performance potentially without the cost of reformulation. A technique has been developed to obtain burning rate data across a range of pressures from ambient to 345 MPa. The technique com...
متن کاملHumidity Control for the Accelerated Aging of Rocket Propellants
Sensitive materials, such as rocket propellants, can be placed in harsh environments of increased temperature and relative humidity (RH) to study the effects of environmental conditions over time in accelerated aging studies. Programmable ovens are common to research laboratories and can be used to regulate the temperature of the aging environment for long durations. Some commercial units inclu...
