The paper presents examples of vibration performances of the naval propulsion systems. It describes the methodology of preparation for measurement, used gauges and their restrictions. The necessity of synchronous measurements had been justified. The work contains also samples of analysis, to facilitate the reader with the components of amplitude-frequency spectra of naval propulsion systems. An overview of the existing normative documents had been presented. At the same time limitations of applying of them during technical monitoring of marine propulsion systems had been presented.

W artykule przedstawiono przykłady diagnostycznych pomiarów parametrów drganiowych okrętowych linii wałów. Opisano metodologię przygotowania do pomiarów, stosowanie urządzeń pomiarowych oraz ich ograniczenia. Uzasadniono konieczność stosowania pomiarów synchronicznych. Przedstawiono przegląd obowiązujących dokumentów normatywnych, zwracając jednocześnie uwagę na ich ograniczenia w procesie monitorowania stanu technicznego okrętowych układów napędowych.

The article describes the inland fleet warships of the Vistula Flotilla and the Pinsk Flotilla in the years 1918-1921. A total of 80 warships have been accounted for, but there is data suggesting that there were at least 98 warships in the two flotillas. The warships were built mainly in the years 1888-1905 (11 warships), but also in the period 1909-1916 (5 warships); 52 craft were taken over from the former authorities of the partitioned Poland and from private owners, while 46 were captured during the war in the east. Typologically the craft included 10 armoured warships, 18 armed warships (among which were three vessels upgraded to that status), 7 light armed warships, 18 transport vessels (including 3 personnel-sanitary vessels and 3 tugboats), 1 hospital ship, and 3 staff command-vessels, as well as 29 armed motor boats of various types (including combat, armoured, reconaissance, and transport motor boats), the latter of which there must in fact have been more, as indicated by their documented tactical numbers „M 47" and „M 51". The numerous barges are not discussed in the article. The warships differed widely as far as their propulsion was concerned - 49 had a steam engine, including at least 2 („Pancerny 1" and „Pancerny 2") which used wood as fuel, while 31 motor boats had internal combustion engines, mainly running on petrol (gasoline). Forty warships had side paddle wheels and two had paddle wheels mounted on the stern, while 27 vessels had screw propellers, including two or three („Kiliński", „Różycki" and perhaps „Bartosz Głowacki") with a tunnel stern (no data is available in the sources for the remaining warships). Also the armament used by the warships showed a great deal of variability. On the whole the armament was being increased in line with the rising numbers of the crews. There was a great variety as far as the types of weapons were concerned; they included heavy, 7.62 mm and 7.92 mm machine guns, 37 mm, 75mm and 80 mm cannons, as well as two heavy 105 mm cannons on the „Andrzej Zamoyski". Most of the cannons were of the field-gun type, which were easier to obtain at a time of great exigency. The warships were protected by wood-and-earth panelling (sand chambers, timber logs) and by steel armour (6-8 mm steel sheets, mainly on the wheelhouses). Since about 1925, the cannons were protected by armoured breastwoorks. Some warships were unique in having armoured barbettes for heavy machine guns („Wawel", „MB 1"). Since 1920 there were radio stations on board the staff command ships („Wisła", „Warneńczyk", „Andrzej Zamoyski"). Modern river monitors and typical navy motor boats, which had been custom-built for combat purposes, were used in the years 1920-1921, but they not have any influence on the inland fleet of the period under discussion; they did however give rise to a new generation of warships known from the inter-war period.

The article attempts to give a general description of the first warships of the Restituted Poland (1918-1921), in terms of technology and the tactical features that they represented.In line with the prevalent political and strategic conditions of the period, duringwhich the Polish statehod was being restored, the Polish navy was an inland fleet,aimed at launching operations on the rivers Vistula and Prypeć (now: Pripyat’), at a time of military threat of German and Soviet expansion. Other urgent needs precluded theconstruction of warships proper, and thus civilian craft (which had previously been takenover, purchased, requisitioned, or obtained from the spoils of war) were adpated formilitary purposes.The precise technical data of the ships remain unknown, for these were very seldomdocumented in times of warfare. Such data are however retrievable from the data on civilianflotillas, available in materials relating to later periods of the inter-war years. Theuse of such materials makes it possible to engage in a plausible reconstruction of suchdata.The craft taken over required adaptation that consisted in partially dismantling thesuperstructures (that related especially to luxury cruisers), and strengthening the deckswhere the artillery was to be installed, including the mounting of turning platforms thatwould facilitate the movements of the cannons. Armoured warships were protected bymeans of sand chambers on the sides of the ships, by timber-log panelling or steel-sheetarmour, which shielded the vessels against draft, shell fragments, shrapnels and smallsarmsfire, but did not guard against immediate impact of artillery shells.The warships were equipped in 105 mm, 75-76 mm and 37 mm cannons (these werelater to be replaced by 47 mm cannons) as well as in heavy machine guns, used by thearmy; apart from that, there were a few cannons mounted on gun rests on a turning base.The cannons used had a fairly wide firing range, which usually combined into a systemof circular firing range.As far as the classification of the warships is concerned, one can distinguish the relativelyheavy armed warships and armoured warships, as well light armed warships, armedreconaissance, combat and armoured motor boats, landing and transport craft, hospitalships, as well as staff command-vessels, and, at the end of the period under discussion,also custom-built monitors. There were also plans to introduce floating batteriesbut such plans were never implemented.The test of the warships came during warfare, in which the ships contributed to manysuccesses of the Polish armed forces.

Podstawą opracowania testów badawczych toksyczności spalin jest widmo obciążeń silnika. Tradycyjne sposoby wyznaczania widma obciążeń okrętowych silników głównych są bardzo pracochłonne oraz nie uwzględniają ewentualnych zmian w planowanym procesie eksploatacji okrętu. Zaproponowana metoda zapewnia określenie w prosty sposób widma obciążen silników dla dowolnych, prognozowanych zmian widma operacyjnego okrętu. Danymi wyjściowymi są zakładane, typowe , o istotnym udziale czasowym, wartości prędkości pływania okrętu oraz jednorazowo wyznaczone charakterystyki układu napędowego. Metodę zilustrowano przykładami zastosowań do oprogramowania testów badawczych silników okrętów wojennych.

To develop the tests for exhaust gas toxicity the engine load spectrum is used. Traditional methods used for determining marine engine load spectrum are very time-consuming and they do not include possible changes in the planned process of ships operation. Owing to the method proposed it is possible to easily determine engine load spectrum, predicted changes in operational spectrum of the ship. The initial data are assumed, typical values of ship speed, of significant time contribution, and determined once only, charakteristics of the propulsion system. The method is illustrated by examples of apllication for tests of engines in naval ships.
