The boundary layer on the wall surface of the nozzle, the wave suppresser and the channel wall itself affects strongly to the velocity profile of the test section of a circulating water channel. The velocity near the free surface is always smaller than the uniform velocity which is normally determined by the mean value at fairly deep position. In order to obtain the uniform velocity near water surface, the rotor method, a jet-like flow generated by the rotor at the edge of the nozzle accelerates the velocity, is employed here. In this paper, it is shown that at first the two-dimensional wake theory represents the velocity defect near the free surface, and the two-dimensional jet flow theory can be used for representing the flow by the rotor itself. The uniformed velocity profile is obtained by superimposed these two prof les. The optimum rotation number of the rotor is theoretically determined as a function of the uniform velocity.

Deep Submergence Research Vehicle "SHINKAI6500" is the latest manned research vehicle which can dive to the deepest existing in the world. The maneuverability of a submersible vehicle is highly dependent on its cofiguration. During the development of "SHINKAl6500" we have assumed great importance to its decending and ascending capability. "SHINKAI6500"'s configuration has been improved in various respects reflecting "SHINKAI2000"'s operation results, finally determined based on the results of twice wind tunnel tests and a tank test. In sea trials it is confirmed that hydrodynamics resistance of "SHINKAI6500" is remarkably reduced compared to that of "SHINKAI2000". This paper describes the outline of these model tests, sea trials and the process of the development of its streamlined cofigulation.

In the previous report 1), 2), the authors discussed the stopping abilities of ships equipped with controllable pitch propeller (CPP), from a viewpoint of both sea trial results and theoretical computation about transient phenomena, by using a one-dimensional equation of ship motion. They described the CPP ship's superiorities in both its easy manoeuvring of astern-going and overa11 stopping abilities. As for the results of theoretical calculation it was found that CPP stopping characteristics can be estimated enough quantitative1y. In this report, the authors describe the fluctuating characteristics of shaft revolution number at CPP crash astern test, by solving simultaneous equations in respect to ship motion and prope11er-shaft revolutional motion. Furthermore, using the about computer program, the authors investigated influence of blade changing time on fluctuation of shaft revolution, CPP blade root strain, etc. It is also very important to investigate on stopping abilities of FPP ships in order to grasp stopping abilities of CPP ships. The authors devide transient phenomena of FPP ships into five ranges and fully examine each of them from actual astern test results. Based on these results, they calculated some transient phenomena of FPP ships with computer program and compare them with actual trial data and make some simulation to find important factors of stopping abilities of FPP ships. Finally they make comparisons of stopping abilities under the same initial condition, between CPP-installed and FPP-installed ships by astern programs for them.

This report mainly describes the 4-quadrant characteristics of the controllable pitch propeller. Using three kinds of models of controllable pitch propellers for high speed container ship, high speed reefer and large ore carrier, we have carried out the 4-quadrant open test at Kawasaki's circulating water channel. From polynominal regression analysis using 0.7R pitch ratio, these open characteristics can be expressed with sufficient accuracy as follows: K_t, K_q = Σ__iΣ__kC_<ik>P^iJ^k Only by this regression formula, the open characteristics can be expressed irrespective of various original pitch and area ratios. In regard to stopping ability, we have solved equations of ship motion by using the characteristics obtained from the above formula and made simulation analysis, and studied effect of C.P.P. pitch angle speed, effect of F.P.P. revolution changing time, and effect of C.P.P. pitch changing pattern for the case of Ship No.1120.

Recently KHI built three kinds of ships equipped with controllable pitch propeller (CPP). They are a reefer, a container and an ore/oil tanker and all of them are higher-powered ships in comparison with those built before. As speed and size of ships increase, necessity of better stopping abilities has been increased. Investigations on the stopping abilities of ships with fixed pitch propeller (EPP) have been reported in detail by many researchers, but those on CPP ships are very rare. As the first step of the investigation on the stopping abilities of ships equipped with CPP, the authors report on crash astern test results, measured at sea trial test of above mentioned ships and compare with those of FPP ships. Furthermore they show the results of computation about transient phenomena in case of CPP ships by using one dimensional equation of motion and compare them with sea trial results.

The "Argentina Maru" is the second ship built in Japan after the last World War which is originally designed as an emigrant ship. Her length and depth are same as the first ship "Brasil Maru", but many improvements have been made on various items. This paper takes up the most outstanding points out of them, such as, to pay more attention to stability, to adopt the sprinkler system for fire protection, and to adopt constant running system for water supply, etc.

Two liberty ships, the "EVILIZ" and the "EVICYNTHIA", were elongated and reconstructed at the Innoshima Shipyard of Hitachi Shipbuilding and Engineering Co. Ltd.. Seizing this opportunity the authors measured the distribution of the locked-in-stresses along the cutted cross section of the vessels. This paper contains the results of measurement and brief consideration on them.

The pressure hull of deep submergence research vehicle is an utmost important structure that secures the safety of crew members against the hydrostatic pressure in deep sea, and should be as compact in size and light in weight as possible in order to obtain easy operation and high maneuverability of the vehicle. In design and fabrication of the pressure hull, the application of high strength material which has reliable characteristic for practical use, of design method suitable for such material and fabrication procedure which satisfies the quality requirement of the highest degree have been encouraged. In the develoment of the 6500m deep submergence research vehicle "SHINKAI 6500", which is the latest submergence research vehicle following the 2000m deep submergence research vehicle "SHINKAI 2000" in Japan, the investigation in various fields was carried out in order to adopt titanium alloy, which has superior strength/weight ratio, for the pressure hull. The production procedure of heavy thickness and large size plate and forging material, and the fabrication procedure of the pressure hull were investigated by the fabrication of the full scale model made of titanium alloy and by material tests with specimens cut from the model. The collapse behaviour was examined by collapse tests using scale models of titanium alloy and by nonlinear behaviour analysis with FEM procedure. Finally, in order to confirm both the fabrication procedure and design method in total, the cyclic loading test and collapse test using scale model fabricated according to the procedure equivalent to that for the actual pressure hull. This paper presents the design and fabrication of the pressure hull of "SHINKAI 6500".
