Additive Manufacturing of High Solids Loading Hybrid Rocket Fuel Grains [PDF]

, 2018
Hybrid rocket motors offer many of the benefits of both liquid and solid rocket systems. Like liquid engines, hybrid rocket motors are able to be throttled, can be stopped and restarted, and are safer than solid rocket motors since the fuel and oxidizer ...

An Investigation into Hybrid Rocket Injectors

, 2020
Propulse NTNU er et nylig oppstartet rakettlag for studenter som nå forsøker å bygge en hybrid-rakett. Fordi dette er en ny organisasjon er det et behov for å samle kunnskap om hvordan raketter og deres nøkkelkomponenter fungerer. En av nøkkelkomponentene er injektoren, og dens rolle er å levere en spesifik massestrømningsrate av flytende oksidant som ...
