This study was performed to analyze the performance of a solid propulsion system quickly
and accurately. Systems that are currently in operation use a propellant with a complicated …

In the design and development of solid propellant rocket motors, the use of numerical tools
able to predict the behavior of a given motor is particularly important in order to decrease the …

VEGA is a small launch vehicle developed by the European Space Agency (ESA) and ELV
SpA, the Italian company in charge of the vehicle system development, integration, and …

A predictive unsteady quasi-one-dimensional internal ballistic numerical model and a set of
performance regulation mechanism formulas are established for throttling segregated fuel …

The problem of pressure oscillations, occurring during the quasi-steady state of aft-finocyl
solid rocket motors, is investigated by using the Q1D model AGAR (Aerodynamically …

I. Introduction ockets based on chemical energy (with solid or liquid propellants) are
currently the only means to access Space. Therefore, research and development of this area …

The estimation of erosive burning is of great importance for the internal ballistics
computation of a solid rocket motor (SRM) with a large aspect ratio. Because of the variety of …

The problem of pressure oscillations in solid rocket motors (SRMs) has received
considerable attention in the past fourty years, especially for the class of large segmented …

Despite the short duration, ignition transient plays a very important role in the whole
operation of a solid rocket motor. A two-dimensional model is proposed to simulate the …

This paper has the aim to investigate the correlation between some ballistic geometrical
parameters of a SRM and the calibration of AGAR Q1D model of the pressure oscillations …
