Hello All,

The Romanian rocket development group called Asociația Română pentru Cosmonautică și Aeronautică (ARCA) or Romanian Cosmonautics and Aeronautics Association (see: www.arcaspace.com/ [click on the British flag for the English text]) has just finished building the first example of their original-design Executor turbopump-fed LOX/kerosene rocket engine (see: www.arcaspace.com/en/home.php ), which produces 23 t (metric tons) of thrust at sea level at a propellant consumption rate of 85 kg/s. The second Executor engine (of their initial batch of 12 engines) is 50% completed. Also:

After ground testing of the Executor engines, they will be flight tested next year in the Haas 2C (see: www.arcaspace.com/en/haas_2C_en.htm ), an 18 m tall expendable SSTO (Single-Stage-To-Orbit) rocket which--if successful--will be the first SSTO vehicle in the world. Lightweight composite construction gives it an empty mass of 510 kg and a fully-fueled mass at launch of 16 t, for a mass ratio of 31.37; this is considerably better than the approximately 20:1 mass ratio that is considered the minimum viable SSTO mass ratio (using the LOX/LH2 propellant combination, if memory serves). In addition:

The Haas 2C will be used for orbiting microsats and cubesats, which typically have masses of < 10 kg. The Bulgarian CubeMessenger satellite, which is being built by BOREAS (Bulgarian Orbital Research and Satellites), is scheduled to be launched aboard a Haas 2C vehicle next summer (see: www.arcaspace.com/en/Comunicat_Boreas.doc ). The Haas 2C rocket is only one of several different vehicle designs that ARCA is developing, which will be powered by one or more Executor rocket engines.

I hope this information will be helpful.
