Airships were not generally considered important before the war. Many thought they would never become practical as a means of transportation. The proper conception of what an airship is having first been explained, the three principal ways in which progress has been made are specified as weight-saving, improvement of overall propulsion efficiency and decreasing resistance and increase in size. The last mentioned feature is discussed in some detail, the conclusion being that practically anything is possible, given an airship of sufficient size. The future needs of airship development are then considered, such as more suitable engines, multiple powerplants, dependability, the development of better fabric and better landing and hangar facilities.

This standard covers Airspeed Instruments which display airspeed of an aircraft, as follows:

This aeronautical standard covers two basic types of instruments as follows: Type I - Pitot Pressure, straight and L-shaped, 12 and 14 volt nominal, 2 wire circuit. Type II - Pitot and Static Pressured, straight and L-shaped, 12 and 24 volt nominal, 2 wire circuit.

This recommended practice covers an instrument which measures and displays angle of deviation of the airstream dependent on mounting location on the aircraft.

The AIRTRANS system now under construction at the new Dallas/Fort Worth Airport is truly a complete intra-airport transportation system. It is designed to carry passengers and employees (in separate cars), transport all interline baggage and mail, remove all trash from the terminals to a central dump, and deliver commissary supplies from a common warehouse to the terminals. It is a fully automatic system with guarantees on trip times and mechanical performance. The system contains some 13 miles of guideway within the airport, 68 vehicles plus service vehicles, and a central control point to provide surveillance over the automatic operation. Automatic container handling equipment is also included in the airlines operations area to ease the task of the airlines. The system has been under design and fabrication since spring 1971.

Continued airworthiness is essential to safety and operation at an economical cost, with profitability as the end result. The material presented explores whether or not Industry and Government are moving in the right direction.

This paper presents an approach in the context of intergranular corrosion process, its causes, effects and its direct relation with the Engineering, once the responsible professional shall consider the numerous losses that may be caused by this deterioration. The intergranular process of corrosion in stainless steel has been studied. A failure occurred by intergranular corrosion in service in Isolator Exhaust, which is critical to the functioning of the air diesel engine system. A microcrack was generated in the grain boundary region due the precipitation of complex carbides, which was aggravated by the working temperature. Given the working conditions of the isolator exhaust, it is suggested to replace the material AISI 304 with AISI 310, for it contains higher percentage of chromium, inhibiting intergranular corrosion occurrence.

Increasing the sintering temperature, lowering the oxygen content, improved the longitudinal and transverse impact properties of powder formed AISI 4027. Flow improved the longitudinal impact properties to a maximum of 53 ft-lbs. but had no effect on the transverse properties. The anisotropy of powder formed preforms was a function of oxygen content and deformation strain. Comparing the powder-formed AISI 4027 to wrought AISI 8620, the powder formed preforms were more isotropic.

The AISI Bar Machinability Sub-committee was formed in 1991 to develop a database of automotive bar steel machinability under single point carbide turning conditions. To accomplish this task more than 30 industrially significant steel grades and their variants have been evaluated in the ensuing years. The test materials were produced by eight different steel companies using various melting and casting practices. Material properties and microstructures were characterized and the machinability of each steel variant was evaluated by at least two different machinability testing laboratories. This paper presents the results of these tests and correlates the machinability of the steels with their properties. The data base thus generated can be used by the machining industry to compare the relative machinability of various steel grades and their properties to make more informed materials application decisions.

AISIN AW has developed a new full hybrid transmission, the HD-10 for front wheel drive vehicles. This HD-10 has been developed based on the concept for improving fuel economy and performance without sacrificing drivability and utility. To achieve this, the transmission adopts an integrated design, which consists of two electric motors, gears including a planetary gear set, two inverters, and an electronic control unit. In addition, new software has been developed to offer smooth operation in every drive condition.

AISIN AW has developed a new FWD 6-speed automatic transmission “TF-80SC” for luxury cars with high torque engines. This newly developed automatic transmission (A/T) is based on the concept of the FWD 6-speed A/T “TF-60SN” that we have already introduced to the world market. The basic concept for the 6-speed A/T is to achieve weight saving and compact as well as better fuel efficiency and driving performance in comparison with conventional 5-speed A/Ts. Of course the shift feel must be the top level in the world, so we increased torque capacity of the TF-80SC to cover luxury cars with high torque engine. One of the outstanding features of the A/T is an advanced band brake that allows simultaneous pursuits of high capacity, weight saving, size reduction and high efficiency as well as high-quality shift feeling qualified for luxury cars. This paper describes the advantages and structure of the new A/T with a focus on our approach to new technology of the band brake system.

AISIN AW has developed a six-speed automatic transmission TF-60SN for front wheel drive (FWD) vehicles. This new TF-60SN has been developed based on the concepts of minimizing length and mass increase as compared with current five-speed automatic transmissions, and providing the world's first transverse FWD six-speed automatic transmission. This has been accomplished using a newly developed planetary gear set, and a new “squeezed” torque converter. In addition, the control system features a unique design that maintains outstanding compactness and achieves a high quality smooth shift feeling. This paper describes the construction, characteristics, and functions of this six-speed automatic transmission.

AISIN AW has developed a new six-speed automatic transmission TR-60SN for rear wheel drive (RWD) vehicles, for use in sports utility vehicles with high torque engines. This new TR-60SN has been developed based on the concept of improving fuel consumption and drivability while minimizing the number of component parts, and covering engine torque of 10 or 12 cylinders. To achieve this, TR-60SN utilizes component parts including gear train, torque converter, oil pump, and casing that have a completely new design. In addition, a new electric-hydraulic control unit has also been developed that offers both world class shift quality and a sporty shift feeling.
