Effect of Nano Particle Addition on the Regression Rate of Liquefying Fuels

51st AIAA/SAE/ASEE Joint Propulsion Conference, 2015
Inclusion of solid additives such as metals or metal hydrides in hybrid rocket fuel formulations introduces the possibility of substantial increase in the specific impulse and density impulse performance. Moreover certain nanometer sized particles with proper surface treatment have the potential to enhance the mechanical properties of the fuel grain ...

Regression rate of paraffin-based fuels in hybrid rocket motor

Aerospace Science and Technology, 2020
Abstract Paraffin-based fuels are regarded as a promising solid fuel for hybrid rocket motor (HRM) owing to high regression rate, excellent mechanical performance, and high dropping point. The regression rate of paraffin-based fuels was characterized by static fire test with nitrous oxide (N2O) and gaseous oxygen (GOX) as oxidizer, and the effect of ...

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.

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

The Enhancement of Regression Rate of Hybrid Rocket Fuel by Various Methods

43rd AIAA Aerospace Sciences Meeting and Exhibit, 2005
Hybrid rocket has been spotlighted recently by its excellent safety in combustion and comparable thrust level although lower density specific impulse and charging efficiency. Thus, many researches have been focused to find the way to increase regression rate. One of the popular methods to increase regression rate is to use a swirl flow of oxidizer. The

Scale effect of fuel regression rate in hybrid rocket motor

Aerospace Science and Technology, 2013
Abstract The scale effect of solid fuel regression rate in hybrid rocket motors is investigated theoretically based on pipe turbulent boundary combustion theory firstly, and a practicable scaling criterion of solid fuel regression rate has been obtained.

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).

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 ...
