Duralumin All-Metal Airplane Construction

1928-01-01
280030
PSYCHOLOGY of the public, as well as engineering structure and aerodynamics, is involved in commercial aviation. The public has confidence in metal. With quantity production in view, the author and his associates considered costs of production as related to quantity and also costs of maintenance at airports and in the field, and chose metal as the material of construction. Structural members are fashioned from sheet duralumin rather than from tubes and a type of construction was evolved that can be made with the minimum investment in tools, that is cheap to put together and that can be repaired with the smallest amount of equipment and labor. For compression loads, duralumin has a great deal more strength for a given weight than has steel. It cannot be used, however, for compression members in combination with steel in tension members because of the difference in coefficient of expansion.

TAXICAB-BODY CONSTRUCTION1

1923-01-01
230015
The author states briefly the phenomenal growth of taxicab usage and consequent demand for this type of motor vehicle, mentioned the differences in body requirements for taxicabs as compared with those of passenger cars, and describes the methods used to secure durability in taxicab-body construction to discount the severe service to which the body is subjected. Tabular data are presented and comments made regarding the woods that are suitable for body framework, and the methods of joining frame members and reinforcing frame joints are outlined. The desirable types of roof and the factors that influence design are discussed at some length, illustrations being presented also, and minor considerations, such as types of hardware, dash and instrument-boards, are included. A brief summary states present conditions, and a bibliographical list is appended of informative publications relating to the subject.

Why Not 125 BMEP in an L-Head Truck Engine?

1939-01-01
390130
HIGH output per cubic inch of piston displacement is desirable not alone for the purpose of being able to transport more payload faster, but more particularly for the invariably associated byproduct of lower specific fuel consumption, and especially at road-load requirements. The only way of accomplishing this purpose is through the use of higher compression ratios, and the limiting factors for this objective are fuel distribution and the operating temperatures of the component parts. A manifold is proposed which not only definitely improves distribution at both full and road loads, but has the inherent additional advantage of reducing the formation of condensate, thus still further facilitating a reduction in road-load specific fuel consumption. Hydraulic valve lifters, obviation of mechanical and thermal distortion, and controlled water flow are the essentials in improved cooling.

Safety in Body Design Through Chassisless Construction

1936-01-01
360148
THE successful development of the chassisless motorcoach and its relation to safety, weight reduction and automotive design are discussed by the author. Pioneer design of this type, made back in 1927 after encountering various difficulties with conventional frames, was followed by successive improvements in design, resulting in the highly developed unit of today. A study is included of the engineering fundamentals primarily involved in the integral or chassisless design versus conventional-frame design from a strength and weight standpoint. This study involves a comparison with other more concrete objects to establish a definite insight to the why and wherefore of these structural changes. The relation to body safety design and its interconnection to weight distribution, vehicle balance, and resistance to crushing are also covered by the author.

Manufacturing Phases of Metal-Aircraft Construction

1936-01-01
360138
THE introduction to this paper includes definitions of the major items under discussion, and is followed by a discussion of the materials most widely used in metal-aircraft construction and their important physical properties. In the remainder of the paper are described some of the problems encountered in metal construction and the processes that have been developed to facilitate manufacture. The following specific items are discussed: (1) Design, (2) Tooling, including lofting, (3) Fabrication, (4) Assembly, (5) Inspection, and (6) Protective coating. Special equipment and tools are illustrated.

practical design suggestions for users of Brazed Honeycomb Sandwich

1959-01-01
590057
SIX BASIC suggestions are offered on how to design for practical, producible, economical structures of brazed honeycomb sandwich. The author illustrates the application of some of these design suggestions and explores the step-by-step theoretical reasoning a designer might use to arrive at a satisfactory design for a hypothetical large missile wing. The final design of a honeycomb sandwich component must take into account the process as well as structural and configuration requirements.

A MASS PRODUCED, ALL WELDED, HIGH TEMPERATURE SANDWICH

1959-01-01
590344
This paper presents some of the history of the Spacemetal process development; a discussion of the core forming machine, a description of the welder where corrugated core and facing sheets are joined; the quality control process employed for inspecting the finished product; and some of the material properties and applications. FOREWORD Development of a production process and the machines for fabrication of a resistance welded steel sandwich was made by Missile Division, North American Aviation, Inc. Development was carried forward under contract AF 33(600)-26154 from the Manufacturing Methods Branch, Industrial Resources Division of the Air Materiel Command USAF.

Construction of a Controlled Environmental Area Utilizing Commercial Construction Materials

1965-02-01
650344
With the growth of the missile and space industry, the controlled environmental, or clean, room has become an accepted and necessary facility for assembly, test and inspection of critical components. The paper describes the construction of such a facility within an existing manufacturing plant. Emphasis is on the use of readily available, commercial construction materials. The intent is not a manual defining exact procedures and methods of construction and maintenance, but rather a description of the concept of one particular clean room influenced as it was by existent circumstances. Included are areas for hydraulic assembly and test, and Lox cleaning and assembly.

Scale Model Evaluation of Earthmoving Tools

1962-01-01
620501
The problem of accurately evaluating the performance of earthmoving tools has been for many years severely handicapped by the variability of field soils. The machine operator also contributes to the variability of field test data, since he cannot accurately reproduce adjustments of the cutting element on successive tests. Minimizing these two factors has been of prime consideration in the establishment of an indoor scale-model testing facility for earthmoving tools, described here. In addition there is a discussion of the soils used, the testing technique, and the type of test results that can be obtained.

The Design and Construction of a Controlled Environmental Area for Hydraulic Assembly and Test

1963-01-01
630357
This paper describes the construction of a clean room within an existing facility. The description of the details shows that areas capable of close environmental control can be developed from commercial construction materials readily available. Controls for such an area may also be relatively simple and routine, but must be regularly scheduled. Thus, at realistic costs, a facility may be constructed that will be more than adequate for supercritical inspection, assembly, and test operations.

Construction and Earthmoving Equipment Requirements in Vietnam

1966-02-01
660236
The engineer troops in Vietnam have had to cope with a number of problems caused by the rapid buildup of troops, the complexity and wide variety of equipment in use, and the resulting high level of skill required of operator and maintenance personnel. This paper describes some of the equipment and procedures developed by USAEDRL for ease of assembly and maintenance, including the sectionalizing of vehicles. The author also outlines maintenance problems encountered in the field, particularly on hydraulic systems and the overall problems of quality control.
