Viscosity and Regression Rate of Liquefying Hybrid Rocket Fuels
Journal of Propulsion and Power, 2017 The combustion behavior of paraffin-based hybrid rocket fuels with gaseous oxygen as an oxidizer has been analyzed in detail. Regression rate tests have been done in a two-dimensional radial microburner at the DLR, German Aerospace Center and at the Space Propulsion Laboratory.

Testing and Modeling Fuel Regression Rate in a Miniature Hybrid Burner
International Journal of Aerospace Engineering, 2012 Ballistic characterization of an extended group of innovative HTPB-based solid fuel formulations for hybrid rocket propulsion was performed in a lab-scale burner. An optical time-resolved technique was used to assess the quasisteady regression history of

Detection of Anomalous Reactor Activity Using Antineutrino Count Rate Evolution Over the Course of a Reactor Cycle [PDF]
, 2010 This paper analyzes the sensitivity of antineutrino count rate measurements to changes in the fissile content of civil power reactors. Such measurements may be useful in IAEA reactor safeguards applications. We introduce a hypothesis testing procedure to

Validation of Integral Method for Numerical Prediction of Hybrid Rocket Internal Ballistics
Journal of Fluid Science and Technology, 2013 In order to design hybrid rocket engines, we developed a numerical prediction method which describes the internal ballistics, thus the solid fuel regression rate. In order to obtain a fast code, simple but efficient models have been implemented.
