Tech/Engineering - Aerospace / Aviation / Space | | Russian term or phrase: газотурбинный контур | I have an idea what this means, but am hoping to verify the english technical term for "газотурбинный контур" as distinct from "газотурбинный контур".
Sample sentence:
(ТПД) — комбинированный многорежимный ВРД для полётов с гиперзвуковыми скоростями (Маха числа полёта М(∞) до 5, при использовании в качестве топлива водорода примерно до 6), содержащий газотурбинный и прямоточный контуры.

It is clear from the explanations below that no one-to-one translation applicable in all instances can be suggested
According to the first reference below,
"Turboramjet = An air-breathing engine consisting of a turbojet engine mounted within a ramjet duct. Intake air is compressed at low speeds by a compressor driven by a turbine and at high speeds by the ram effect of the engine moving through the air. At low speeds, the engine operates as a turbojet. Between Mach 1 and 2, the ramburner begins to operate and provides a greater portion of the thrust until speeds of approximately Mach 3.5, when the turbojet is shut down and the ramjet provides all of the thrust. During all operating modes, high-temperature combustion gases are expanded through the exhaust nozzle to produce thrust. Like the turbojet-ramjet, the turboramjet engine provides the efficiency of a turbojet during takeoff and low-speed flight and the efficiency and high thrust of a ramjet during high-speed flight (up to Mach 6). A turboramjet engine is the same as a turbofan-ramjet engine or turbojet-ramjet engine"
Compare this to the Russian description at hand:
- "содержащий газотурбинный и прямоточный контуры" (= "combining a turbojet and a ramjet") <-> "consisting of a turbojet engine mounted within a ramjet duct"
- "вначале (от взлёта до умеренных сверхзвуковых скоростей полёта) работает только газотурбинный контур" <-> "At low speeds, the engine operates as a turbojet"
- "подача топлива в газотурбинный контур прекращается" <-> "the turbojet is shut down"
The remaining Russian phrases containing 'контур' can be translated into standard terms used in engineering contexts as follows:
- "ТПД с последовательной работой контуров" ~ "TRJ operating in serial mode"
- "[наличие общей для контуров] форсажно-прямоточной камеры сгорания" ~ "[the use of] a ramburner/afterburner [common to both engines]"
- "В ТПД с отдельной камерой сгорания прямоточного контура возможна параллельная работа контуров" ~ "A TRJ with a separate ramburner can operate in parallel mode"
- "газотурбинный контур может быть переведён на режим авторотации для привода агрегатов двигателя" ~ "the turbojet can be employed in an autorotation mode to drive engine accessories"
- "При использовании в газотурбинном контуре ТПД двухконтурного двигателя повышается экономичность ТПД" ~ "The use of a two-stage turbine in the turbojet [engine] improves the the fuel efficiency of the TRJ"
A good overview of TRJ and related engine concepts can be found in the second reference (Chapter 2)
Note:
The use of "turbojet circuit" is incorrect since it connotes a totally different concept in aviation terminology
- see
http://en.wikipedia.org/wiki/Airfield_traffic_pattern
Example
"Also, there may be a jet circuit at a higher altitude, EGHH for example have a turbojet circuit at 1500', so try an overhead join and you may meet a Falcon coming at you"

5 mins confidence:  
55 mins confidence: here: turbojet circuit
Explanation:
vs. ramjet circuit
A literal rendition, "gas turbine", looks worse and bears no extra meaningful information compared to "turbojet". What we need here is a juxtaposition - turbojet vs. ramjet.
I'd prefer "circuit" over a "duct" because the latter refers mostly to a physical pipe whereas the former is more abstract and may denote an ensemble of devices of any complexity and/or a principle upon which these devices operate.
