Session 3aNS: Noise 3aNS6. Prediction of nonlinear propagation of noise from a solid rocket motor
*Corresponding author's address: Physics and Astronomy, Brigham Young University, N283 ESC, Provo, UT 84602, [email protected] Generalized Burgers equation-based predictions of noise propagation are compared with measurements from a static, horizontally-fired solid rocket motor over a range of 76-1220 m during an 80 s burn time. The modeling suggests the nature of the geometric spreading betw...
متن کاملOne Dimensional Internal Ballistics Simulation of Solid Rocket Motor
An internal ballistics model has been developed for performance prediction of a solid propellant rocket motor. In this model a 1-D unsteady Euler equation with source terms is considered. The flow is assumed as a non-reacting mixture of perfect gases with space and time varying thermo physical properties. The governing equations in the combustion chamber are solved numerically by using the Steg...

متن کاملEarly Detection of Solid Rocket Motor Case - Breach Failure ∗
This paper describes work on early detection of space launch vehicle failures that could lead to loss of control during ascent. The particular focus is on the Solid Rocket Motor (SRM) comprising First Stage of the Crew Launch Vehicle (CLV). Some of the most important failure modes leading to loss of vehicle control are caused by hot gases ejected from the SRM combustion chamber through a case b...
متن کاملSpatial modelling of railway noise propagation
In recent decades, population growth and progress of technology have shaped large and compact urban settlements. Existence of huge transportation systems and developed urban infrastructures are among the most important properties of modern cities. In spite of prompt transit and facilitated daily activities, development of transportation systems causes many problems, including traffic, air and n...
