What is a Fastener?

Fastener is a hardware device that mechanically joins or affixes two or more objects together.
Fasteners can also be used to seal containers such as bags, boxes, or envelopes, or they may involve keeping together the sides of the opening of flexible material, attaching a lid to a container, etc. There are also special-purpose closing devices, such as bread clip. Fasteners are used in behavior is often temporary, in the sense that they may be tied up and off repeatedly.

Some types of wood joints utilize a separate internal reinforcements, such as a pen or a biscuit, which in some sense can be considered fasteners within the scope of the system together, even though their own they are not general purpose fasteners.
Furniture package included in flat form often uses cam pen locked by cam locks, also known asconformat fasteners.

Items such as, string wire rope, (e.g. metal wire, possibly coated with plastic, or a parallel cable that is guarded by a plastic strip coating), cable, chain, or plastic wrap can be used to mechanically join objects, but generally not categorized as fasteners because they have additional general use. Likewise, hinges and springs may join objects together, but usually not considered fasteners because their primary purpose is to allow articulation rather than rigid affixment.

What is Fly By Wire Flight Control System?

What is Fly By Wire Flight Control System?

N250 Aircraft-Indonesian Aircraft Industry Designed using Fly By Wire System

Fly by wire is a system that replaces the conventional manual flight control aircraft with an electronic interface. Flight control movement is converted into electronic signals transmitted over cable (hence the term fly-by-wire), and the flight control computer determines how to move the actuator at each control surface to provide a response commands. System of fly-by-wire also allows the signal sent by the computer automatically aircraft to perform functions without pilot input, such as in a system that automatically helps to stabilize the aircraft.

After eliminating mechanical transmission circuits in the fly-by-wire flight control system, the next step is to eliminate the bulky and heavy hydraulic circuit. Hydraulic circuit is replaced by an electrical circuit. Electrical circuits power electrical or electrohydraulic actuators are controlled independently by a digital flight control computer. All the benefits of fly-by-wire maintained.

The biggest benefit is the weight savings, the possibility of redundant power circuits and tighter integration between the aircraft flight control systems and avionics systems company. The absence of hydraulics greatly reduces maintenance costs. This system is used in the Lockheed Martin F-35 Lightning II and the Airbus A380 flight control backup. Boeing 787 will also incorporate some electrically operated flight controls (spoilers and horizontal stabilizer), which will continue to operate with either a total hydraulic failure and / or flight control computer failure.

A new cargo plane crashes in France, and the National Transportation Safety Board sends Jammer Davis to investigate in Larsen’s latest thriller. Davis’ superiors want easy answers, and the easiest answer of all is “pilot error.” The plane has a sophisticated fly-by-wire design; if the crash was due to manufacturing, the economic cost of all the cargo shipments screeching to a halt would be catastrophic. Jammer has his doubts, however, and his investigation reveals a shocking conspiracy that has ties to a rash of terrorist bombings at oil refineries. Larsen is fast becoming a thriller writer to watch. He clearly knows his subject matter and has a knack for writing about technology without it getting in the way of the story or the characters. Fans of the aviation thrillers of John Nance and of Michael Crichton’s Airframe (1996) will find much to enjoy here. --Jeff Ayers.

What is Tool Design?

How is a Tool Design on Design Process?

Production planning and tool design that does more than plan how to mass produce the project and the tools should be used in manufacturing parts. Task to resolve in this step including selecting materials, selection of production processes, determining the sequence of operations, and selection tools, such as jigs, fixtures, and tooling. This task also involves the testing of working prototypes to ensure parts are designed to meet qualification standards.

Here is a tool design guide selection:

Jig and Fixture Design

What is a Design Review on Engineering Design Process?

A design review is a milestone in the product development process where the design was evaluated against the requirements in order to verify the results of previous activities and identify issues before, - and if necessary re-prioritize - further work. The main design review, if successful, thereby triggering a product launches, or releases the product.

Implementation of design review is required as part of the control design, when developing products in the context of certain regulated as medical devices.

By definition, the review should include people outside the design team.
Autodesk has a file viewer and commenting tools for industrial architecture, engineering and construction called Design Review.

In order to evaluate a design against the requirements, a number of means can be considered, such as:
Physical test.
Simulation techniques.
Inspection (Walk-through).

Most of the systems engineering process formalized acknowledge that the cost of correcting errors increases as it progresses through the development process. Additional effort is spent in the early stages of development to find and fix errors because it may be beneficial. Design review is an example of that effort. Therefore, the number of design reviews can be done, for example, to evaluate different designs against set criteria (consistency, usability, ease of localization, and the environment) or during various stages of the design process.

Design Review Minutes
Use this section to explain when and how the minutes of the meeting should be generated:
• Indicate if there is a meeting does not require a minute.
• Indicate who is responsible to record and distribute minutes of each meeting. You can indicate a specific person or role (eg, "Lead Design").
• Show how or where the minutes will be made available to team members.

Aircraft Design Concept Sketches

Engineering design process is a multi-step process including research, conceptualization, feasibility assessment, requirements of building design, preliminary design, detailed design, production planning and design tools, and finallyproduction. Section to follow the steps that are not always in the engineering design process, for some tasks are completed at the same time as other tasks. This is only general summary of each step of the engineering design process.

Conceptual Design Process
Having clearly defined engineering problems, the solution must be identified. This solution can be found by using the desire, or mental processes by which ideas generated. The following are the most widely used techniques:

trigger words - words or phrases related to the issue at hand is expressed, and the following words and phrases that evoke. For example, to move something from one place to another could lead to run, swim, roll, etc.

chart morphology - independent design characteristics are listed in the table and different engineering solutions proposed for each solution. Typically, early sketches and a brief report accompanying chart morphology.

Synaptic - engineers imagine themselves as the item and asked, "What would I do if I was the system?" Conventional methods of thought may find solutions to problems encountered.
Brainstorming - This popular method involves thinking of different ideas and adopts these ideas in some form as a solution to this problem

Conceptual Design Phase Diagram for Aircraft Design

A Conceptual Design is the initial image that shows the ideas that have been formulated after the master plan has been developed or are asked to do a survey on candidates or current
boating facility site.

Conceptual design drawings will include the following:
- The title sheet which provides a map where the site is located within the state,
water body, the area, the agency responsible.
- A picture of the existing site plan. This will show existing site conditions including
previous repairs and site topography.
- Conceptual site plan will indicate the proposed repairs. If necessary we
engineers will give you more than one option to consider.

This is a good time to seek input from staff and users to determine whether what has been the proposed layout is acceptable. Our engineers can tweak the design to meet your needs. Conceptual provided can help determine whether your project will require a permit.

We suggest you contact our Environmental Coordinator to determine the steps to obtain necessary permits for the project. We will provide initial cost estimates. These cost estimates will help determine what you
institutions will require a match and what to ask for grant funds from the board. Council guidelines for the minimum proportion of matching funds in the form of combined cash and in the form of the game, according to the type of applicant are: Local Entities, 25%, State Institutions, 25%, the Federal Agent, 50%.

What is a Preliminary Design Stage Definition?

Where the Preliminary Design Phase?

Preliminary design stage may also be known as conceptual design or architectural design. During this phase, the high level design concept is created, which will implement the requirements of complex electronics. The design concept can be expressed as a functional block diagram description, design and architecture, sketches, and / or behavioral HDL (hardware description language).

The focus of the preliminary design is to determine the approximate dimensions, weight, force, load limits and other physical characteristics to the optimal plane, it is best to maximize value for the competition. The main areas of concern are the wing area, span and size of the empennage. Routines are modeled based on the conceptual design; carefully consider the specific needs of competition.

The purpose of the design phase (early and detailed) is to create a design that would really and truly implement the requirements. For the preliminary design stage, the main purpose is to map out how the complex electronics will perform the functions specified in the requirements, within the limits of the device, the interface is defined, and the device will operate in the environment. At this stage, the designer must maintain perspective and see the operating system of complex electronics in concert with the entire system. Now is the time to identify inconsistencies, misunderstandings, and ambiguities.

Design assurance objectives are to verify that the design has to implement all the requirements, and that it implements nothing but the requirement. Any deviations (such as additional functions which may indicate missed requirements) are reintroduced into the process engineering requirements.

The main design activities for the preliminary design phase are:

- Create high-level design descriptions.
- Identify the major components, including third-party modules or IP cores.
- Any derived requirements resulting from this process is fed back into the requirements engineering process
- Any omissions or errors are resolved
- Include reliability, maintenance, and test the features necessary to meet the performance requirements and quality, and to ensure that testing can be performed to verify the requirements.
- Identify constraints on other system elements that are the result of high-level design.

This assurance process for complex electronics assumes that the requirements of complex electronics have been developed assessed, and baseline (formalized). In fact, these requirements can be included in the specification of higher-level assembly requirements, such as circuit boards or sub-system. Requirements for complex electronics will likely be a work in progress, as the design decisions in other areas of the system influences the function CE devices will appear. Management requirements will be an important process throughout the design, implementation, and testing phases.

Who is a Design Engineer?

A design engineer is a general term covering a range of engineering disciplines including electrical, mechanical design, industrial and civil engineering, architectural engineers in the U.S. and building engineers in the UK.

The design engineer is distinguished from the designer / drafter by the fact that a design engineer to take care of the total system as well as the inner / engineering design. A design engineer to create the initial blueprints and schematics for various structures, systems, machinery, or equipment. He or she is part of the design team that includes designers and civil engineers or mechanical lead.

While the industrial designer may be responsible for aspects of aesthetic and ergonomic design of the conceptual, design engineers usually work with a team of engineers and designers to develop designs, conceptual and detailed initial and most critical part. He / she may be working with industrial designers and marketing to develop product concepts and specifications, and he / she may direct the design effort from that point. Products are usually designed with input from several sources such as marketing, manufacturing, purchasing, tool making and packaging techniques. In addition to dealing with system design engineers and scientific technology is much more complex (aircraft, spacecraft, rockets, trains, ships, dams, bridges, building structures, urban infrastructure, machines, production systems, propulsion systems, oil, gas, and the system exploration of mining, manufacturing processes, military systems, cars, electronics, computers, power systems - nuclear, fossil, wind, marine, and power distribution systems). In many areas of engineering, distinction is made between design engineers and planning engineers in the design. Planning engineers are more concerned with designing at the system level is more engineering, and overlap into the operational side is often required. Design engineers, by contrast, are more concerned with designing a specific new product or system. Analysis is important for planning engineers, while the synthesis is essential for design engineers.

Most advance design engineers use computer technology and applications, such as computer-aided (CAD) design software, to help them create and test virtual models. Depending on the type of structure or machine being built, a design engineer may be asked to build a physical model or prototype to test in a realistic situation. Designers work in many different government organizations and industry, including research and development companies, construction companies, and plants manufacturing products.

When the design involves public safety, the design engineer is usually required for a license, for example a Professional Engineer in the U.S. and Canada. Usually there is an 'industrial exemption' for design engineers working on internal projects for the company and does not provide professional services directly to the public.

Mechanical Drafting and Design

Cranksaft design

Mechanical drafting is a means by which mechanical design engineers design product and create instructions for manufacturing parts. A mechanical drafting can be a model of a computer or hand-drawn schematic showing all dimensions necessary to manufacture parts, and assembly records, list of materials needed, and other related information. An American mechanical design engineer or skilled worker who creates technical drawings may be cited as the drafter or draftsman. Historically the process of drafting the two-dimensional, but the computer-aided design (CAD) program now allows designers to create in three dimensions.

mechanical drafting and design

Instructions for the manufacture must be fed into the machine as needed, either manually, through programmed instruction, or through the use of computer-aided manufacturing (CAM) or combined computer-aided design CAD / CAM programs. Optionally, an engineer can also manually manufacture parts using mechanical drafting, but this is a rare increase, with the advent of the computer manufactures numerically controlled (CNC). Engineers primarily manually manufacture of components in the field of applied spray coatings, finishes, and other processes that can not be economically or practically performed by a machine.

The preparation is used in almost every profession of mechanical engineering, and by other branches of engineering and architecture. Three-dimensional models created using CAD software is also often used in finite element analysis (FEA) and computational fluid dynamics (CFD).

What is a Digital Mock Up (DMU)?

What is a Digital Mock Up (DMU)?

aircraft digital mockup

Digital mockup or DMU is a concept that allows the description of the product, usually in 3D, for the entire life cycle. Digital mockup enriched by all the activities that contribute to describe the product. The product design engineers, manufacturing engineers, and support engineers work together to create and manage the DMU.

The digital mockup allows engineers to create a virtual assembly of aircraft components.
No need anymore to test empirically the interminable use physical mockups and prototypes. The digital mockup is the only point of reference for the product in the company.

The smallest details can be visualized and take into account in the design. The digital mockup also ensures that data can not be lost, everything is stored in a single computerized repository, rather than spread among multiple images. Everything is integrated by a digital mockup, the structure is completed and the system (cables, tubes, equipment installation, etc.) defined upstream in the finest detail, which greatly facilitate programming machine tools and assembly robots. A direct link was established between design and production, which will continue to be strengthened during the following years.

One goal is to have the essential knowledge of the future or the product is supported for replacing physical prototypes with virtual, using 3D computer graphics techniques. As an extension it is also often referred to as Digital Prototyping or Virtual Prototyping. The second definition refers specifically to the production of physical prototypes, but they are part of the concept of DMU. DMU allows engineers to design and configure complex products and validate their design without ever needing to build a physical model.

Among the techniques and technologies that make this possible are: the use of lightweight 3D models with different levels of detail using data structures such as JT lightweight XVL and PDF enables engineers to visualize, analyze, and interact with large amounts of product data in real-time on standard desktop computers. Direct interface mockups for Digital and PDM systems. Active digital mockup technology that unites the ability to visualize the assembly mockup with the ability to measure, analyze, simulate, design and redesign.
