It means "located/belonging to/confined in a flat plane (of 2 dimensions)", as opposed to a gimball that makes the engine trace a sphere, typically. So, instead of rotation we have translation.Thanks zaitcev for that explanation !But I don't understand how the engine can translate with a hinge ??Maybe my English is not correct. Do we agree that a "hinge" is this thing ?

It sounds like the "hinge" is simply a gimbal that can only move in one dimension. The 6 main engines on Proton are arranged like that, they can only gimbal in one direction, out or in.

A rocket engine that can gimbal in one direction allows for limited translation, without simultaneous support from the ACS.
Someone knows when this system made its maiden flight on Fregat?http://npcap.ru/napravleniya-deyatelnosti/novyie-i-perspektivnyie-razrabotki/integrirovannaya-inerczialno-astro-sputnikovaya-sistema-navigaczii.html

ASN first flight in normal mode (i.e. its data were used by BTsVM) was on 17 September 2009. Since that time there were 20 Fregat flights with ASN worked in normal mode. Also ASN has worked in telemetry mode on last DM-SLB flight. NPTs AP wants to use ASN in normal mode on next DM-SLB flight, but it depends on customer's permission. ASN will be installed on DM-03 too. In next DM-03 flight it will work in telemetry mode.
