Hot fire tests were performed with a single-injector research combustor featuring a large
optical access window (255x38 mm) for flame visualisation. Three test campaigns were
conducted with the propellant combination of liquid oxygen and hydrogen (LOX/H2), liquid
oxygen and compressed natural gas (LOX/CNG), and liquid oxygen and liquefied natural
gas (LOX/LNG) at conditions relevant for mainand upper-stage rocket engines. The large
optical access enabled synchronized flame imaging using ultraviolet (OH*) and blue (CH*) …
