A numerical method for solid propellant grain design

Design and Geometrical Analysis of Propellant Grain Configurations of a Solid Rocket Motor

Design and analysis of propellant grain configurations for determination of the grain geometry which is an important and critical step in the design of solid propellant rocket motors, because accurate calculation of grain geometrical properties plays a vital role in performance prediction. The performance prediction of the solid rocket motor can be achieved easily if the burn back steps of the ...

A novel design of MEMS based solid propellant

As the development of small satellites, more commonly referred to as ‘microsats’ with masses in the range of 10-100 kg and ‘nanosats’ featuring masses from 1-10 kg, there emerge several new kinds of space missions, such as the formation flying and constellations of micro satellites, distributed onboard carrier wave radar, high resolution synthetic aperture remote sensing etc. Due to the continu...

HTPB-Polyurethane: A Versatile Fuel Binder for Composite Solid Propellant

High Altitude Plume Simulations for a Solid Propellant Rocket

A simulation scheme is proposed for flowfield and radiation analysis of solid rocket exhaust plumes at high altitude. Several recently developed numerical procedures are used to determine properties of the gas and condensed phase Al2O3 particles, and spectrally resolved plume radiation calculations are performed using a Monte Carlo ray trace model. Simulations are run for a representative plume...

Numerical method for a moving solid object in flows.

We propose a numerical method for dealing with a moving solid body that interacts with a complex liquid surface. The method is based on the level set method, the CIP method, and the ghost fluid method. The validity of the method was shown by applying it to Poiseuille and Couette flow problems. The method can precisely capture the boundary layer as well as a moving solid object.
