AIR SYSTEM OF TURBOPUMP PLANT OF HYDRAULIC TORPEDO LAUNCHER TUBE

摘要

FIELD: weapons and ammunition.SUBSTANCE: air system of a turbopump plant of a hydraulic torpedo launcher tube comprises an air turbine, a compressed air cylinder, a cut-off valve and an air flow controller. The cylinder outlet is connected to the turbine by a pipeline via the cut-off valve and the air flow controller. The pipeline comprises two control stages, systems of air filling of the main cylinder, control of controller and cut-off valve operation with the help of a cutter. The system of cut-off valve control includes at least two cutters connected in parallel. In the air pipeline between the outlet from the cylinder and the controller there is a controlled switch installed for switching modes of operation of the turbopump plant. The switch of modes comprises limiters of air pipeline section - throttles, and by number of cutters - channels of their communication with the air pipeline.EFFECT: reduced noise during torpedo firing.3 dwg
