Since being introduced to North America at the Miami Boat Show in 2005, Volvo Penta Inboard Performance System, or IPS has established itself as a leading propulsion choice among pleasure boat owners and builders. Other suppliers are following suit including the Cummins Mercruiser Zeus system. Pod propulsion offers benefits like increased efficiency, better performance, nimble handling, and low noise levels while allowing more people to successfully operate their vessel due to a friendly operator interface. Features of these commercial pod systems that also benefit builders include ease of installation and the integral underwater exhaust which helps to meet CE requirements, for both exhaust and noise levels. Both IPS and Zeus are fully integrated pod propulsion systems. Existing vessels can be retro-fitted with these systems while many new vessels are being designed specifically for IPS or Zeus. Donald L. Blount and Associates provides consulting in regards to IPS integration with existing and new designs and has also been involved with designs employing the Zeus system. The first portion of this paper discusses pod drives, particularly IPS itself. (Because the author has substantially more experience and background with IPS, much of the information herein is IPS specific). General information on IPS and Zeus is offered as well as some operational specifics. The paper then focuses on the application of pod drives in existing and new vessel designs. The discussion includes how hull forms can be evaluated for use with pod drives. A look at the integration of pod systems into various types of pleasure boats (cruiser, day boat, fishing yacht, etc) is also covered including the challenges which exist for each specific vessel type.

Liquid Methane

A comprehensive programme of work on the development of liquid methane as a motor fuel was started in 1938 in the Department of Chemical Engineering and Applied Chemistry, Imperial College. This paper describes some of the work concerned with the actual utilization on the vehicle. The factors affecting power output and fuel economy are discussed, and engine test results obtained at the laboratories of Messrs. Ricardo and Company, Engineers (1927), Ltd., are presented. Work on the development of a suitable vacuum-insulated fuel tank is described with particular reference to “neck losses”. The vehicle fuel system and its components as finally developed are described, and the results of long-distance service trials of a motor ‘bus with the normal and a higher compression ratio are given. A disadvantage of liquid methane with the fuel system used so far is the loss of fuel by evaporation; the paper ends with a description of fuel systems which enable this loss to be virtually eliminated.

Toroidal Traction

Continuously variable automatic transmissions can bring improved fuel economy benefits under good speed ratio changes for automobile propulsion systems in which engines can produce their power under optimum conditions. These systems require computer control for the calculation of optimum speed ratio. The paper presents design features of the electrohydraulic interface between micro-computer and cone-roller toroidal traction drive CVT, dynamic characteristics of cone roller motion, and test results of the practical computer control of CVT.

In order to look into the causes of fire response and post-fire bearing capacity of the steel tubular columns protected with different materials, the fire test was conducted for a set of circular steel tubes protected with different materials such as gypsum fireproof panel, bamboo plywood and the ordinary lumber core plywood, and the steel tube without any protective material. The fire response temperature of surface of steel tubes is measured and the axial compressive bearing capacity of the specimens after fire are tested and analyzed. The test results show that gypsum fireproof panel has the best fire protection characteristics, the ordinary lumber core plywood and bamboo plywood can also retard rising of the surface temperature of the steel tubes during the initial 35min although they are combustible materials. It is found that the post-fire bearing capacity of the steel tubes protected with different materials varies evidently, and the maximum value of response temperature has the greatest effect.

The article discusses fire test results according to EN 45545-2 [1] requirements, for various material groups which were tested at Instytut Kolejnictwa (Railway Research Institute) for Polish producers. Approach to evaluation of CCS equipment and electrical equipment to meet the requirements of fire protection are characterized. Areas of requirements of the EN 45545-2 [1] standard are also presented, which are a challenge for the Polish railways, i.e. producers and research laboratories.
