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...

The CubeSat Ambipolar Thruster (CAT) is nominally designed to operate on inert gas propellants with a target ΔV capability of greater than 1000 m/s. The design process for a prototype pressurized inert gas propellant feed system capable of storing enough propellant to meet this target and of delivering propellant at the flow rates of 5 15 sccm of xenon and pressures of 1 10 mbar required by CAT...

Military training with howitzers and mortars produces excess propellant that is burned on the training range and can result in point sources containing high concentrations of unreacted propellant constituents. Propellants contain energetic compounds such as nitroglycerin (NG) and 2,4-dinitrotoluene (2,4-DNT), both of which are found at firing positions and propellant disposal areas. To quantify...

CUBESATS are relatively new spacecraft platforms that are typically deployed from a launch vehicle as a secondary payload,1 providing low-cost access to space for a wide range of end-users. These satellites are comprised of building blocks having dimensions of 10x10x10 cm 3 and a mass of 1.33 kg (a 1-U size). While providing low-cost access to space, a major operational limitation is the lack o...
