Determing co-operation characteristics of the naval gas turbine with power receiver using the technique of planning experiment

Pojawa B., Borsuk K.

Journal of KONES

2012

Vol. 19, No. 3

345-353

The process of exploitations naval gas turbines bases on their characteristics, in this on characteristic of co-operation of engine with power receiver. In particular, if a controllable pitch propeller is it. The ship’s documentation does not often contain that kind of characteristic. There is need the study of method her determine therefore. It undertaking the test of determination the characteristic of co-operation of chosen naval gas turbines with power receiver, it was decided to execute in analytic way, using the technique of planning experiment which also allows for efficient and effective testing. Taking preliminary character of examinations into account they decided to carry them out on the laboratory position with the gas turbine engine GTD-350 and single-stage reduction gearing H-564 co-operating with Froude HWZ-3 water brake. In the article theoretical bases of planning experience, a manner of preliminary implementations of studies as well as their results were presented. It the investigation of adequacy for received results of investigations was conducted, in this statistical and technical analysis. The conclusions on basis of received results of investigations of adequacy were expressed.

Using the technique of planning experiment for appointing characteristics of the naval gas turbine

R. 50, nr 3

In the process of the routine exploitation naval gas turbine the most important for exploiter is cooperation characteristic engine and his power receiver, in particular if a controllable pitch propeller is it. Because of the fact that ship's documentation does not often contain the that kind of characteristic, they undertook the attempt for her to appoint. Taking preliminary character of examinations into account they decided to carry them out on the laboratory stand with the gas turbine engine GTD-350. Appointing the mathematical model of above characteristics is an issue folded, requiring applying the theory of planning experience. In the article a manner of preliminary implementations of studies and their results were presented. Next results of statistical and contentrelated analysis of received findings and conclusions expressed on their base.

W procesie eksploatacji okrętowych turbinowych silników spalinowych, spośród charakterystyk eksploatacyjnych, najistotniejszą dla eksploatatora jest charakterystyka jego współpracy z odbiornikiem energii. W szczególności jeżeli jest nim śruba o skoku nastawnym. Z uwagi na to, że dokumentacja okrętowa często nie zawiera tego rodzaju charakterystyki, podjęto się próby jej wyznaczenia. Mając na uwadze wstępny charakter badań, postanowiono je wykonać na stanowisku laboratoryjnym z turbinowym silnikiem spalinowym GTD-350. Wyznaczenie modelu matematycznego powyższej charakterystyki jest zagadnieniem złożonym, wymagającym zastosowania teorii planowania doświadczeń. W artykule przedstawiono sposób realizacji badań wstępnych oraz ich wyniki. Następnie wyniki analizy statystycznej i merytorycznej otrzymanych wyników badań oraz sformułowane na ich podstawie wnioski.
