Hybrid rocket propulsion, first demonstrated by the Russian GIRD-09 rocket in 1933,
combines liquid oxidizer and solid fuel for thrust generation. Despite numerous advantages …

This paper deals with a performance comparison of the control algorithm for a variable-thrust
solid-propellant rocket motor (VTSRM). To do this, we develop a simulation model of a …

The growing demand for cheaper space access calls for a more economically and
environmentally sustainable approach for launchers. Concurrently, the shift to smaller …

Small satellites with less than 500 kg mass have come back with improved capabilities. The
small satellites are the stepping stone for new comer coming to the space field. Mass and …

A multidisciplinary design optimisation (MDO) study of a hybrid rocket launcher is presented,
with a focus on quantifying the impact of using composite overwrapped pressure vessels …

As the global market for small satellites grows, the demand for small launch vehicles rises as
well. In addition, the accelerated technological development of battery and motor have …

The two dimensional gravity turn problem is addressed allowing for the effects of variable
rocket mass due to propellant consumption, thrust and thrust vector angle, lift and drag …

Most communication satellites which drive the economy of the world today are launched and
positioned on the equatorial orbit, which has the same rotational period as the Earth …

This chapter presents an overview of past and ongoing small satellite-related initiatives in
Brazil and discusses the importance of these initiatives on several fronts such as education …

The work focuses on optimizing the pressurization system's operating performance for a fuel
tank of a turbo-pumped liquid propellant rocket engine. This system is the most complex and …
