Nitrous Oxide Hybrid Rocket Motor Fuel Regression Rate Characterization

43rd AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2007
This study presents data relevant to the regression rate of various hybrid rocket fuels using nitrous oxide (N20) as the oxidizer, which were obtained using the Stanford Sub-scale Hybrid Test Facility. The fuels investigated include Hydroxyl Terminated Polybutadiene (HTPB), Polymethyl Methacrylate (PMMA), High Density Polyethylene (HDPE), sorbitol, and

Novel, High-Regression Rate Fuels For Hybrid Rocket Motors

2017
A series of fuels for hybrid rocket engine of our design were developed and tested. Poly(methylene oxide), paraffin wax and epoxy-based compositions were made, characterized by means of measured thrust, c*, Isp, thermal stability (DSC, TG) and chemical composition (FTIR).

Measurement of Fuel Regression Rates in a Jet Fuel Pool Fire in Crosswind

Volume 4, 2004
Fire modeling software has become increasingly important for the prediction of fire development in industrial and transportation accident scenarios. A key parameter required as input to fire models is the rate at which the fuel load is consumed, often reported as the fuel regression rate.

Regression Rates of Solid Fuels Containing High Nitrogen (HiN) Materials

47th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2011
The combustion behavior of novel energetic formulations in solid fuels to replace conventional, low-energy, binders such as hydroxyl-terminated polybutadiene (HTPB) were examined. The proposed solid fuels will provide higher enthalpy, higher density, and improved rocket engine performance.

Cost and performance payoffs inherent in increased fuel regression rates

33rd Joint Propulsion Conference and Exhibit, 1997
Current fuel regression rate technology is such that it requires relatively large and inefficient fuel grain design configurations. Today's low fuel regression rates result in grain designs that require many ports and thereby cause poor fuel volumetric loading efficiency and increased grain complexity. The traditional wagon wheel design can be tailored

Geometric effects of fuel regression rate in hybrid rocket motors

Science China Technological Sciences, 2016
The geometric configuration of the solid fuel is a key parameter affecting the fuel regression rate in hybrid rocket motors. In this paper, a semi-empirical regression rate model is developed to investigate the geometric effect on the fuel regression rate by incorporating the hydraulic diameter into the classical model.

Enhancement of Hybrid Fuel Regression Rate Using a Bluff Body

Journal of Propulsion and Power, 2014
In this paper, an attempt is made to increase the regression rate of the hybrid fuel (paraffin wax) using a hemispherical bluff body placed near the head end of the motor. The oxidizer used for the present study is gaseous oxygen. The results show that the use of a bluff body increases the regression rate by around two times at the higher Gox (15  g ...
