Description
(54) БУЛЬБОВАЯ НАДЕЛКА ВЫКРУЖКИ КОРМОВОЙ ОКОНЕЧНОСТИ КОРПУСА СУДНА(54) BULB FIXTURE OF FASTENING OF THE SHIP END OF THE SHIP BODY
Изобретение относитс к судостроению.This invention relates to shipbuilding.
Известна булкбова наделка выкружки кормовой оконечности корпуса судна, содержаща сужающеес в сторону кормы утолщение , охватывающее гребной вал судна с подъемом в сторону его кормовой оконечности.The famous bulkba trimming of the fillet of the aft end of the hull of the vessel, containing a thickening tapering towards the stern, covering the propeller shaft of the vessel with a rise towards its aft tip.
Однако сопр жение утолщени с корпусом судна ло V-образным шпангоутам приводит к турбулизащии потока вблизи судна и возникновению кавитации.However, the conjugation of the bulge with the hull of the vessel to the V-shaped frames leads to a turbulant flow near the vessel and the occurrence of cavitation.
Наиболее близким техническим решением к олисьиваемому вл етс бульбова наделка выкружки кормовой оконечности корпуса судна , содержаща сужающеес в сторону кормы утолщение, охватывающее гребной вал судна с подъемом в сторону его кормовой оконечности и сопр женное с корпусом судна по S-образным шпангоутам, причем корпус судна имеет диаметральную плоскость.The closest technical solution to the one being sourced is the bulbous trimming of the fillet of the stern end of the hull, containing a stern narrowing towards the stern, covering the propeller shaft of the vessel with a sway to the stern end and adjacent to the hull on the S-shaped frames, and diametral plane.
Цель изобретени - улучшение условий обтекани корпуса судна путем снижени веро тности кавитации.The purpose of the invention is to improve the conditions around the hull of the vessel by reducing the likelihood of cavitation.
Это достигаетс тем, что утолщение бульбовой .наделки .выкружки выполнено сужающимс в районе сопр жени с кормовой частью корпуса судна.This is achieved by the fact that the bulge thickening of the crop is thickened at the interface with the stern of the ship hull.
Кроме того, бульбовую наделку целесообразно ВЫПОЛНЯТЬ несимметричной относительно диаметральной плоскости корпуса судна. На фиг. 1 схематически изображено описываемое устройство, вид сбоку; на фиг. 2-то же, вид в нос судна; на фвг. 3 - то же, вид сверху; на фит. 4 - схематически изображено описываемое устройство при несимметричной наделке, вид сбоку; на фиг. 5 - то же, вид вIn addition, the bulb fitting should be executed asymmetrical with respect to the median plane of the hull. FIG. 1 shows schematically the described device, side view; in fig. 2 is the same, the bow view of the vessel; on fwg. 3 - the same, top view; on fit. 4 is a schematic representation of the described device with an asymmetrical trim, side view; in fig. 5 - the same view in
нос судна; на фиг. 6 - то же, вид сверху; на фит. 7 - схематически изобралчено описываемое устройство при несимметричной наделке у двухвинтового судна, вид сбоку; на фиг. 8 - то же, вид в нос судна; на фиг. 9 - то же, видship's nose; in fig. 6 - the same, top view; on fit. 7 is a schematic depiction of the described device in the case of an asymmetrical finishing of a twin-screw vessel, side view; in fig. 8 - the same, a view in the bow of the vessel; in fig. 9 - the same view
сверху.from above.
Кормова оконечность корпуса судна содержит гребной винт 1 с гребным валом, имеющим ось 2. За винтом 1 расположен руль 3. Корпус имеет диаметральную А и основную БThe stern end of the hull contains a propeller 1 with a propeller shaft having an axis 2. A rudder 3 is located behind the propeller 1. The case has a diametrical A and main B
плоскости. Кроме того, теоретический чертеж корпуса отражен плоскост ми ватерлинии В, Г, Д, Е, Ж, плоскост ми S-образных батоксов И, К, л, М и плоскост ми щпангоутов Н, О, Н, Р.plane. In addition, the theoretical design of the hull is reflected by the planes of the waterline C, D, E, E, F, the planes of the S-shaped buttocks I, K, l, M and the planes of the flanges H, O, H, R.
Описываемое устройство содержит сул ающеес в сторону кормы утолщение 4, охватывающее гребной вал с подъемом в сторону кормовой оконечности корпуса судна и сопр женное с ним но 111иа По там П, О, П и Р.The described device contains a thickening 4, which is located towards the stern, covering the propeller shaft with a lift towards the aft end of the hull and associated with it, but there it is, O, P and R.
Утолщение 4 выполнено сужающимс в районе сопр жени с «ормовой частью корпуса судна.Thickening 4 is made tapering in the mating area with the outer part of the hull.
Такое выполнение бульбовой наделки выкружки кормовой оконечности корпуса позвол ет улучшить услови его обтекани как при одновальной, так и двухвальной гребной установке судна.Such an embodiment of the bulb trim of the filet of the aft end of the hull makes it possible to improve the conditions of its wrapping both in single-shaft and double-shaft rowing installations of the vessel.
