The Single-Blow Problem Including the Effects of Longitudinal Conduction

The results are presented from a numerical finite-difference method of calculation for the transient behavior of porous media when subjected to a step change in fluid temperature considering the case where the longitudinal thermal heat conduction cannot be neglected. These results, given in tabular and graphical form, provide a useful means for evaluating the heat-transfer data obtained from the transient testing of compact heat-exchanger surfaces.

The Use of Gas Turbines as Marine Auxiliary Machinery

The design and development of two related gas turbines, both intended in the first instance as marine auxiliary generators, is described. General matters concerning gas turbines in marine applicatons are touched upon, such as thermal efficiency and design life, and the relevance of these matters to these particular engines discussed.

FT4A Gas-Turbine Engine for Marine and Industrial Applications

The major design features of the FT4A gas-turbine engine for marine and industrial applications are described, the development-test history of the engine is reviewed, and the field experience with this and similar engine concepts is discussed. In addition, the particular characteristics of the FT4A power plant which make the latter attractive for various applications are mentioned.

Installation and Operation of the Model LM100 Turboshaft Engine Aboard the HS “Denison”

This paper reviews the modification, installation and utilization of an aircraft turboshaft engine in a hydrofoil ship. A detailed description of engine performance, maintenance, and corrosion protection is included.

The Allison Turboprop Aircraft Engine as an Industrial Prime Mover

At the 1962 ASME meeting in Houston, Allison submitted a paper describing the possibilities of industrializing the T56 aircraft engine. Since that time, Allison has modified the engine for gas burning and is operating one as a prime mover for a 2000-kw generator at the Indianapolis Plant. In addition, two additional units are to be installed in the gas-transmisson field driving centrifugal gas compressors. This paper gives a description of the units and a status report on the installation and operation. Photographs of the installation and performance data, as necessary to complete the report, are included.

Turbomachinery Characteristics of Brayton-Cycle Space-Power-Generation Systems

This paper presents the results of an analytical study of turbomachinery requirements and configurations for Brayton-cycle space-power systems. Basic turbomachinery requirements are defined and typical effects of such system design parameters as power, temperature, pressure and working fluid on turbomachinery geometry and performance are explored. Typical turbomachinery configurations are then presented for systems with power outputs of 10, 100 and 1000 kw.

The Regenerative Gas Turbine in the Total-Energy Picture

An illustration is given of the considerations necessary in the application of a regenerative gas turbine to a total-energy system involving electric power, heating and air conditioning. Performance of the turbine is compared to a nonregenerative type. Requirements of a modern downtown office building based upon actual operating records for the year 1962 are matched against the turbine’s capabilities for supplying the system.

Combustion-System Design for Industrial Gas Turbines

Some of the problems encountered in combustion-system design are discussed with particular attention to combustor discharge-temperature patterns. The results of extensive laboratory and field tests that culminated in improved temperature patterns are presented.

The Lift/Cruise Fan Propulsion System for VTOL Applications

The high by-pass ratio tip-turbine driven lift and lift cruise fan offers the unique arrangement of a single type propulsion system fulfilling the many requirements for a VTOL application. This simple, compact, lightweight system offers high efficiency (low SFC) with the high static thrust at take-off required for VTOL and STOL operation. The lift cruise fan is a logical outgrowth of the tip-turbine lift fan technology backed by over 600 hr of testing since 1959. The significant test problem accomplishments for the cruise fan are presented as well as a representative VTOL transport-type application.

The Sea Experience of Bristol Siddeley Marine Gas Turbines

The paper presents the experience gained by Bristol Siddeley Engines Limited, over the first five years of operation at sea of aviation gas turbines adapted for use in various marine installations. Most of the experience accumulated during this period has involved the “Proteus” engine and the first part of the paper is devoted to covering this aspect, commenting upon matters such as engine life, failures, current development and future applications. The shorter experience gained applying engines to hovercraft is then dealt with, and finally reference is made to the current activities at Bristol Siddeley concerning the use of the “Olympus” engine for marine purposes.
