Enhancement of Volumetric Specific Impulse in HTPB/Ammonium Nitrate Mixed Hybrid Rocket Systems by Jacob W. Forsyth, Master of Science Utah State University, 2016 Major Professor: Dr. Stephen A. Whitmore Department: Mechanical and Aerospace Engineering Hybrid rocket systems are safer and have higher specific impulse than solid rockets. However, due to large oxidizer tanks and low regression rat...

An instrumentation system was developed to measure the opacity of a hybrid rocket plume as a function of optical wavelength. The source consisted of collineated beams from two lasers, providing seven wavelengths in a single probe beam. Detection was accomplished with a spectrograph equipped with a photodiode array. Previous work with a two-wavelength system demonstrated the ability to follow th...

The paper shows a full 6 DOF modeling for a GRAD rocket in Earth’s non-inertial frame. For numerical purposes the modeling is limited to flat Earth approximation. The full motion equations are shown and all terms are explained together with the aerodynamics parameters for the entire flight envelope. Non-linear interpolation is used for aerodynamic coefficients and their derivatives. We present ...

Design and Testing of Digitally Manufactured Para n Acrylonitrile-Butadiene-Styrene Hybrid Rocket Motors

Coagulation factor XI was purified from human plasma using ion-exchange chromatography and affinity chromatography on high molecular weight kininogen-Sepharose. A monospecific precipitating antiserum was prepared and used to study factor XI antigen. Factor XI did not migrate during electrophoresis at pH 8.3. High molecular weight kininogen (HMWK), an alpha globulin, reversibly associates with f...

In missile propulsion technology it is conventional to employ solid rocket boosters. These boosters are loaded with solid propellants, which are energetic compositions where raw materials are comprised of solid particulates, such as fuel, and oxidizer particles, in which are dispersed and immobilized throughout a binder (polymeric) matrix. The processability of these compositions is not simple ...

As technology has advanced, electronic components and systems have become smaller and more powerful. A similar trend holds for space systems, and satellites are no exception. As payloads become smaller, so too can the launch vehicles designed to carry them into orbital trajectories. An energy analysis shows that a rocket system with as low as tens of kg of fuel can be sufficient to deliver a 10...

Numerical 2D simulation and research on internal flow field and external flow field of rocket motor nozzle using FLUENT software. Analyze the flow condition of internal flow field and external flow field, and according to add in the amount of the different gas components, obtain the clear distribution of contour of density flow field, pressure flow field and various material components and so o...
