Viability of an Electrically Driven Pump-Fed Hybrid Rocket for Small Launcher Upper Stages

Aerospace, 2019
An electrically driven pump-fed cycle for a hybrid rocket engine is proposed and compared to a simpler gas-pressurized feed system. A liquid-oxygen/paraffin-based fuel hybrid rocket engine which powers the third stage of a Vega-like launcher is ...

Analysis of low-thrust liquid rocket engines with a methane air pump unit

Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2016
The first airplane working on cryogenic fuel was developed in the USSR in early 1980s on the basis of the passenger aircraft Tu-154. It was then modified using a hydrogen engine installed instead of one of the three kerosene engines.

Diversity of design knowledge for launch vehicle in view of fuels on hybrid rocket engine

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2014
A single-stage launch vehicle with hybrid rocket engine, which uses solid fuel and liquid oxidizer, has been studied and developed as a next-generation rocket for scientific observation due to the advantages as low cost, safety, re-ignition, and reduced ...

Investigation of the cooling film distribution in liquid rocket engine [PDF]

Journal of Aerospace Technology and Management, 2011
This study presents the results of the investigation of a cooling method widely used in the combustion chambers, which is called cooling film, and it is applied to a liquid rocket engine that uses as propellants liquid oxygen and kerosene.
