Australian Domain Name System

The Australian Domain Name System is a hierarchical naming system for computers, resources or services connected to the internet. This is done through domain names assigned to each participant of the Australian Domain Name System. It translates domain names to humans in binary terms associated with networking equipment to locate and address these devices worldwide. In a sense, its like an internet super phone book as it translates human friendly computer hostnames into Internet Protocol Addresses. The Australian Domain Name System distributes the task of assigning domain names and maps them to IP addresses in that country by designating authoritative name servers intended for each domain.

Authoritative name servers are responsible for their particular domains which in turn assigns other authoritative name servers designated for their sub domains. This makes the Australian Domain Name System distributed and fault tolerant which has helped avoid the need meant for a single central register towards being continually being consulted and updated. The Australian Domain Name System in general also stores other types of data such as the mail servers list which accepts email for a given web domain. DNS is an essential part of the Internets functionality by providing a worldwide dispersed keyword based redirection service.

A number of other identifiers could potentially use DNS such as RFID tags, International characters in host names and email addresses, UPC codes and the likes. The Australian Domain Name System defines the technical aspects of the functionality of this file service. It also defines the DNS protocol as part of the IP suite. The DNS Protocol gives a detailed specification of the communication exchange and the data structures used in Australian DNS. An Australian Domain name is an ID label which defines a realm of administrative authority, control or autonomy on the internet in the country, based on this Domain Name System.

An Australian Domain name is used in various application specific names, networking contexts and addressing purposes. It is organized in sub domain levels of the DNS root domain. The first level set of names is called TDLs or Top Level Domains including gTDLs (generic) and ccTDLs (country code). Some examples of which are the prominent .com, .net and .org domains. Below these TDLs are the second and third level domain names which are typically open for end user reservations wishing to connect local area networks or LANs in the country.

They can also use an Australian domain name to run websites on the internet and create publicly accessible net resources. These domain names are sold by domain name registrars who administer these domains to the public. Individual internet host computers utilize domain names as hostnames. These are the leaf labels in DNS usually without further sub domain name space. They appear as a component in URLs or Uniform Resource Locators for internet resources like websites. These Australian domain names are also utilized as simple identification labels in order to indicate control or ownership of a resource like SIPs or Session Initiation Protocols.

System for rapid manufacturing of replacement aerospace parts

Method for the rapid manufacturing of aerospace replacement parts 100 is provided, including removing an in-service aerospace part from an aerospace system 120. The present invention further includes placing the in-service aerospace part into a three-dimensional scanning device 130.

The invention then scans the in-service aerospace part utilizing the three-dimensional scanning device to develop a three-dimensional scan 140. A computer-aided-design model is then developed based on the three-dimensional scan 150. The invention then direct metal fabricates a replacement aerospace part from the computer-aided-design model utilizing layer-build technology device 170. Finally the replacement aerospace part is installed back into the aerospace system 180.

Aerospace and military applications often provide unique challenges to design and manufacturing. The nature of these applications often requires limited run and small-lot productions that result in high cost because of the small quantity of individualized assemblies. Part cost can be extremely expensive due to the cost of tooling and long lead-time associated with developing and fabricating the tooling. If these costs are associated with initial build, they are even more prevalent in dealing with replacement parts for aging aircraft and military applications.

Replacement parts for aging aircraft and other systems commonly arise where the tooling that produced the original parts is no longer in existence. Additionally, the parts “as designed” may not in fact interface correctly into the existing systems. When this situation arises, a complete redesign of part layout and tooling may be required at considerable expense. In addition, where original tooling is no longer available, redevelopment and fabrication of tooling is often required. This can result in undesirable costs associate with supply of the replacement parts. Also, on occasion, it may be necessary to build more parts than are actually needed to help amortize the costs of the tooling. This, however, can result in large inventory costs that counter the cost savings associated with the larger production runs.

What is needed is a cost effective and productive method of supplying replacement parts in limited runs without the negative costs associated with the redevelopment of specialized tooling. Additionally, it would be highly desirable to have a method of supplying replacement parts that addressed the problems associated with in-service parts no longer matching original design specifications. If such a system were developed it would eliminate the costs associated with specialized tooling, long lead time development, and large inventory.

It is therefore an object to the present invention to provide an apparatus and method for the rapid manufacturing of aerospace replacement parts that provides relief from the costs and long lead-time associated with the development and fabrication of tooling. It is further object to the present invention to provide an apparatus and method for the rapid manufacturing of aerospace replacement parts that would address small lot productions and components that no longer match original design configurations.

In accordance with the objects of the present invention a method for the rapid manufacturing of aerospace replacement parts is provided. The method includes removing an in-service aerospace part from an aerospace system. The in-service aerospace part is placed into a three-dimensional scanning device. The present invention further includes scanning the in-service aerospace part. The present invention then develops a computer-aided-design model based on the three-dimensional scan. The present invention finally includes direct metal fabricating a replacement part from the computer-aided-design model utilizing a layer-build technology device.
