New engine testing campaign announced in Twitter, starting in June.

Talking about a 30% power increase, to be tested initially for >1 min duration static fire.

Meanwhile, final review of Arion-1 is about to start, with static fires by the end of this year.

They look quite shorter than that: I'd say 80-100 cm long at most.

They are showing some progress:

After 2 years of liquid rocket engine testing, performing dozens of hot firings, at PLD Space we are ready to accomplish our next giant leap.

Indeed, in the video description they are announcing the unveiling and first testing of a new regeneratively-cooled engine.

Very nice writeup (in Spanish) in Daniel Marin's blog, on PLD's plans and achievements.


http://danielmarin.naukas.com/2017/06/28/pld-space-dos-anos-de-pruebas-de-motores-cohete-en-espana/


Some snippets:


- Tests so far have used a calorimetric model, not machined on the outside (simple cylinder shape), for simplicity and to ease measurements. The 32-kN engine is a real-scale prototype for the Arion-1 single-stage suborbital launcher.


- Immediate plans call for the test of TEPREL-A, with a 110-s burn time, the same as the nominal first stage burn time of Arion-1.


- TEPREL-B will be the second iteration of the engine, with a 165-s burn time.


- Finally, TEPREL-C, to be tested before next year, will be the qualification version of the real Arion-1 engine.


- First (suborbital) flight of the Arion-1 is expected for NET April 2018, from El Arenosillo (Huelva, Spain). It will demonstrate a 220 km apogee trajectory for a 100 kg payload.


- Orbital launches with Arion-2 would follow in their long-term strategy after that, with first flight pencilled-in for 2021.

Today we have the honour to introduce the new combustion chamber TERPEL-A, the new regenerative cooling rocket engine.

El nuevo motor cohete regenerativo de @PLD_Space ruge con fuerza. Comportamiento mecánico y térmico nominal. Muy pronto vídeo completo.
The new regenerative(ly-cooled) rocket engine from PLD_Space roars powerfully. Mechanical and thermal behaviors are nominal. Complete video coming up very soon.
