PLD Space Tests its New Regeneratively Cooled Engine
PLD Space started its endeavour in mastering liquid-propulsion for rocket engines back in 2013 when they managed at that time to close a seed investment round of €1 million.
After almost two years of hard work and developments, and being only four engineers, they had built from ground up the first private test facilities in Europe to test rocket engines. They also developed from scratch, and tested, the first liquid-rocket engine using kerosene and liquid oxygen (aka KeroLOX) as propellants – an engine capable of reaching three tons of thrust at sea level.
After more than 45 hot firings of the first version of this rocket engine (a calorimetric model used to understand the behaviour of the combustion and the performance of the engine), they were ready to upgrade their liquid rocket engine.
Some weeks ago, PLD Space set a new milestone after having tested their new regeneratively cooled engine for 20 seconds. The new rocket engine model uses some tubing around the nozzle and combustion chamber where the fuel passes through, taking away some of the heat and allowing the engine to work for much longer periods of time.
PLD Space will keep extending the duration of these tests until it can qualify it for a nominal mission, around 130 seconds of continuous burning.
