Retractable instrument for submarine, has filter surfaces arranged and aligned in operational position, where force is produced during driving of instrument through water and supported by extending and running instrument

摘要

#CMT# #/CMT# The instrument (5) has filter surfaces (30, 35) arranged and aligned in an operational position, where the filter surfaces are a part of a flow body, and sides of the instrument are connected with each other. Force is produced during driving of the instrument through water and supported by extending and running the instrument. The flow body comprises a form of a wing (20). The flow body is integrated in a stand-by position in a cross sectional contour of the instrument, and includes the filter surfaces. #CMT#USE : #/CMT# Retractable instrument for a submarine. #CMT#ADVANTAGE : #/CMT# The filter surfaces are arranged and aligned in the operational position, where the force is produced during driving of the instrument through water and supported by extending and running the instrument, thus extending and retracting a submarine against water resistance by utilizing the force in a fast manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic side view of a retractable instrument with a pair of wings in an operational position. 5 : Retractable instrument 10 : Snorkel opening 20 : Wing 30, 35 : Filter surfaces 40 : Pivoting axis.
