Inspired by the superhydrophobicity of the waxy layer on lotus leaves, researchers are in
constant pursuit in fabricating advanced wax-based superhydrophobic surfaces. This article …

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 presents the status of developments worldwide regarding use of hybrid rocket
motors for space transportation. Historical roots are presented and reasons for revisiting …

The low regression rate of Hybrid Rocket Engines (HREs) is one prominent characteristic
that is addressed in most abstracts concerning hybrid propulsion. Over the years …

Human spaceflight, space tourism, and the launch of microsatellites are all expected to grow
in the future. In fact, with the recent increase of the satellite market, almost 1000 smallsats …

A new system design tool for the simulation of a full hybrid rocket engine is developed in this
article. This tool enables to simulate the behaviour of the engine at different conditions …

Paraffin-based fuel has a great potential for several innovative missions, including space
tourism, due to its safety, low environmental impact, high performance and low cost. Despite …

A series of firing tests have been performed on a laboratory-scale hybrid rocket engine of
200 N class, fed with gaseous oxygen through a converging nozzle injector, to assess the …

Hybrid rocket engine (HRE) performance is dependent on fuel/oxidizer selection and fuel
grain geometry. A literature review was performed to identify key trends and findings related …

A novel methodology for the calculation of the surface temperature of liquefying fuels
typically burned in hybrid rockets is proposed. This procedure stems from the formulation of …
