A new kind of power engine, the gas turbine engine, is now in the inital stage of its development. The design of the GTU-20 gas turbine engine permits the unit method of assembly and disassembly to be used. The engine proper consists of the following components which are delivered assembled for installation 1 two turbocompressors with drive box, starter, mounted on one frame with an automatic control system oil, water, fuel, and electrical systems the so-called turbocompressor unit tcu 2 air cooler assembled 3 regenerator assembled for regenerator model 4 air passages and gas passage with compensators. The turbocompressor unit, air cooler, and regenerator are able, by virtue of their size and weight, to be transported and installed assembled. It must be noted that the GTU-20 gas turbine engine, by virtue of its characteristics, can be successfully used both to drive a ship propeller as well as for other installations, including fixed power engineering works. At present, each GTU-20 engine before delivery passes through long plant tests under complete load for the purpose of a comprehensive and careful design checkout as well as a check of the engines reliability for many hours of operation under load.
