hi...to all bloggers ...so far in my life i noticed that something special in your life is always necessary,
and this special success is of any kind ...you never come to know about it...some peoples realise whats the thing will be going to give them a huge success or may be a huge disappointment....
i m writting this post with a reason because still i don't know what i have to do in my life....
i have decided to do merchant navy after my b.tech but i still don't know if i can make it or not ..and after that i want to be a car designer.....
But for a success in life ,sometimes i feel that its not enough ,atleast merchant navy but as a car designer if i m able to make design at my best i ll surely get some respect and a bit of taste of success in my life....
and i want some suggestion what guys i mean you make you feel every time enthusiastic, for your dream ..how you guys live upto your dreams and follow that...

Mechanical Component Reverse Engineering Project Examples

2012-05-25T17:50:00.002-07:00

Reverse engineering may be required when a component or its spare parts are no longer available, or the component is failing or not functioning properly and the original manufacturer cannot provide the necessary engineering support to correct the problems. The goal in such cases is to generate the necessary technical information to support, replace, or improve the component.

Examples of LCE reverse engineered components include:

Fire-fighting sprinkler valves
Air-conditioning and refrigeration system packed and packless valves (see below)
Mechanical seals
Air conditioning system dryer housing assembly
High temperature bolt/washer assembly
Bleed-air valve components

AC System Valve

The application was a 7/8 inch AC system valve on U.S. Navy ship for which there was no OEM spare part or maintenance support, no similar commercial valves available, and no drawings available. We reverse engineered the 21 individual parts not available off-the-shelf, including determination of dimensions, tolerances, material specifications, heat treatments and surface coatings, and prepared detailed drawings suitable for competitive bid and procurement.

One-Inch Long Aircraft Bolt

No documentation was available. We determined the bolt material to be A286 and the washer to be Inconel 718 through chemical analysis of drillings and matched to corresponding AMS specifications, the threads to be rolled vs. cut and the presence of an aluminum coating through metallurgical evaluation, and the thread shape to be UNJF (controlled root radius) through dimensional inspection, including multiple inspections to establish required tolerances. We prepared the below drawing suitable for competitive bid and procurement.

Iran to 'reverse engineer' US drone

2012-04-15T22:15:00.000-07:00

Iran claimed that it had begun exploiting a US drone equipped with the latest radar evading technology on Monday as officials warned that the downed machine could be shared with America's rivals.

By Damien McElroy, Foreign Affairs Correspondent

3:37PM GMT 12 Dec 2011

Parviz Sorouri, an MP on parliament's foreign policy committee, said that Iranian experts were in the final stages of recovering the data from the surveillance drone, which was captured on Iranian territory last week.

Tehran has paraded the loss of the drone as a blow to the US and claimed it plans to reproduce the technology. It said its security forces had shot the drone down using previously secret air defence systems.

The drone, which is made from the latest 'stealth' technology, has been presented as a valuable windfall for its defence scientists.

"Our next action will be to reverse-engineer the aircraft," Mr Sorouri said. "In the near future, we will be able to mass produce it. Iranian engineers will soon build an aircraft superior to the American (drone) using reverse engineering."

Other Iranian officials have hinted that it could allow American rivals such as China the opportunity to acquire the technology. American officials used diplomatic pressure to recover similar technology on helicopter that crashed in Pakistan during the raid to kill Osama bin Laden, the al-Qaeda leader.

Washington has acknowledged the loss of the drone but said that it crashed after it lost contact with its controllers while operating over Afghanistan.

The RQ-170 Sentinel drone is one of the most advanced used by the US military and is equipped with technology also used on the US Airforce fleet of advanced fighter jets, the F-22 and F-35.

While some US experts have cast doubt on the authenticity of a model of the drone shown on US television, others have said its electronics would be a valuable prize for rival states.

Peter Singer, of the Brookings Institution think tank, told a US newspaper that the drone would make a technological leap easier. He said: "Bottom line, it's never easy to reverse-engineer anything, let alone something like a radar, but having a working or even damaged system in hand to study up-close makes it a heck of a lot easier to both defend against it in the future or build your own derivative."

Electro Chromatic Auto Dimming Mirror | Opto Electronic Sensor Uses In Glare Free Rear View Mirror And Side View Mirror | Smart Glass With SPD Technology

2012-04-12T03:50:00.001-07:00

Electro-chromatic mirrors system:

Electro chromatic mirrors / Auto dimming mirrors use a combination of opto electronic sensors and complex electronics (sensors, circuit boards, micro-controllers, etc.) that constantly monitor ambient light and the intensity of light shining directly on the mirror. As soon as sensors detect glare, the electro chromatic surface of the mirror becomes darker to protect driver’s eyes and their concentration.

The electro chromatic technology usually is applied to the inside rearview mirror / Side view mirror, where it basically saves you the trouble of flipping the mirror manually if blinded by the light which increases driving safety.

Working operation of Electro chromatic mirrors:

This auto dimming rearview mirror is installed on higher end vehicles. It consists of two lenses that sandwich an electro chromic (electronic color changing) gel. The inside sides of the lenses are coated with a transparent conductive layer coating and the deepest lens has a reflective coating.

This gel, when charged with electricity darkens, then clear once the glare is no longer detected. The mirror uses a forward sensor which measures the outside ambient light, and a rearward sensor to look for glare. When dark enough, it sends current to the electrostatic gel, darkening it a rate which is related to the level of ambient darkness and rearward glare. When the outside ambient light increases, the current decreases, until the gel is clear again at daylight light levels.

Where planes go to die: Massive £22bn air force 'Boneyard' revealed in high resolution by Google Earth Read more: http://www.dailymail.co.uk/news/article-1253068/Massive-22billion-air-force-scrap-yard-revealed-high-resolution-Google-Earth.html#ixzz1rfUE6kyv

It's where old planes go to die - a 2,600-acre patch of U.S. desert where several generations of military aircraft are stored in what has been dubbed 'The Boneyard'.

The $35billion (£22billion) worth of outdated planes is kept as spare parts for current models at Davis-Monthan Air Force Base in Tucson, Arizona.

End of the line: The 2,600 acre site is home to 4,200 aircraft, of which 80 per cent are used as spare parts for the current U.S Air Force fleet

Four of the numerous types of military aircraft kept at the site in Arizona

Some planes are merely stored at the base between deployments, but for more than 80 per cent of the 4,200 aircraft that call it home, it is a cemetery of steel - 350,000 items to be called on when needed.

Now see the image for yourself on Google Earth

The base is home to the 309th Aerospace Maintenance And Regeneration Group (309 AMARG) which carries out repairs to the craft and even gets some of them flying again.

Engines, munitions, wiring and electronics are all recycled to help lower the cost of maintaining the current-day fleet. In 2005, staff at the facility recycled more than 19,000 parts worth $568million (£366million).

The U.S. government even allows the military in other countries to buy parts and even planes from the site.

The facility is the size of 1,300 football pitches.

The site has been a curiosity for eagle-eyed Google Earth users since the satellite imagery software was launched in 2005, but now for the first time it is available to view in high resolution.

The desert is a perfect place to store the mass of steel, because low humidity and rainfall means very little rust occurs. In addition, the hard soil means they can be parked up without the need for building concrete ramps.

The military has used Davis-Monthan as a plane storage facility for 60 years, and in recent years its unique landscape has been called on by Hollywood for such films as Transformers.

One of the reasons why the aircraft are kept here is because in the desert there is low humidity and rainfall which means very little rust occurs

NASA Forgot How To Go To The Moon!!!

2012-04-10T07:20:00.001-07:00

Found this today and broke out laughing...

With all the renewed talk about "Did they go to the Moon" this is quite timely

Seems they forgot how they got to the moon... You would think they had the notes somewhere but Nope... they don't..

Just like they lost the Moon tapes...

The Saga Of the Lost Space Tapes NASA Is Stumped in Search For Videos of 1969 Moonwalk
www.washingtonpost.com...

...it seems they don't have the plans on how they built the moon ships... and no one is left working for NASA that remembers how they did it...

so they are REVERSE ENGINEERING Saturn V parts and scrounging in space junk yards to relearn how to do it...

With all the Shuttle delays and accidents... now they tell us they have to figure out how to get back to the Moon

You have just GOT to see this...

NASA scientists going to junkyards to find parts to figure out how to do it

This is the best film I have seen for a long time... its got to be a classic

Reverse engineering of machines

2012-04-10T03:08:00.002-07:00

As computer-aided design (CAD) has become more popular, reverse engineering has become a viable method to create a 3D virtual model of an existing physical part for use in 3D CAD, CAM, CAE or other software.^[5] The reverse-engineering process involves measuring an object and then reconstructing it as a 3D model. The physical object can be measured using 3D scanning technologies likeCMMs, laser scanners, structured light digitizers, or Industrial CT Scanning (computed tomography). The measured data alone, usually represented as a point cloud, lacks topological information and is therefore often processed and modeled into a more usable format such as a triangular-faced mesh, a set of NURBS surfaces, or a CAD model.

Reverse engineering is also used by businesses to bring existing physical geometry into digital product development environments, to make a digital 3D record of their own products, or to assess competitors' products. It is used to analyse, for instance, how a product works, what it does, and what components it consists of, estimate costs, and identify potential patent infringement, etc.

Value engineering is a related activity also used by businesses. It involves de-constructing and analysing products, but the objective is to find opportunities for cost cutting.

Reverse engineering for military applications

Reverse engineering is often used by militaries in order to copy other nations' technologies, devices, or information that have been obtained by regular troops in the fields or by intelligence operations. It was often used during the Second World War and the Cold War. Well-known examples from WWII and later include:

Jerry can: British and American forces noticed that the Germans had gasoline cans with an excellent design. They reverse-engineered copies of those cans. The cans were popularly known as "Jerry cans".
Tupolev Tu-4: Three American B-29 bombers on missions over Japan were forced to land in the USSR. The Soviets, who did not have a similar strategic bomber, decided to copy the B-29. Within a few years, they had developed the Tu-4, a near-perfect copy.
V2 Rocket: Technical documents for the V2 and related technologies were captured by the Western Allies at the end of the war. Soviet and captured German engineers had to reproduce technical documents and plans, working from captured hardware, in order to make their clone of the rocket, the R-1, which began the postwar Soviet rocket program that led to the R-7 and the beginning of the space race.
K-13/R-3S missile (NATO reporting name AA-2 Atoll), a Soviet reverse-engineered copy of the AIM-9 Sidewinder, was made possible after a Taiwanese AIM-9B hit a Chinese MiG-17 without exploding. The missile became lodged within the airframe, and the pilot returned to base with what Russian scientists would describe as a university course in missile development.
BGM-71 TOW Missile: In May 1975, negotiations between Iran and Hughes Missile Systems on co-production of the TOW and Maverick missiles stalled over disagreements in the pricing structure, the subsequent 1979 revolution ending all plans for such co-production. Iran was later successful in reverse-engineering the missile and are currently producing their own copy: the Toophan.
China has reversed engineered many examples of Western and Russian hardware, from fighter aircraft to missiles and HMMWV cars.
During the Second World War, British military intelligence at the Bletchley Park centre studied captured German "Enigma" message encryption machines. Their operation was then simulated on electro-mechanical devices called "Bombes" that tried all the possible scrambler settings of the "Enigma" machines to help break the coded messages sent by the Germans.

Reverse Engineer an Indy Car with Nikon Metrology’s optical scanning system

2012-04-09T23:23:00.002-07:00

This blog article was written by John Parry. We have re-posted this blog entry because Voxdale used Nikon Metrology’s optical scanning solution to achieve their results.

This work by Voxdale was done a couple of years back, not that long after Voxdale was founded, which makes it all the more impressive, and was done for Champ Car, now merged with Indy Car. The project was to optimize the existing Panoz chassis for Conquest Racing’sChamp Car – now unified with Indy Car.

The first hurdle Voxdale encountered was having no CAD files to work from. Their solution was to scan the entire car using a Nikon Metrology optical laser scanning system to produce a STL point cloud with better than 0.3mm accuracy – reverse engineering at its best!

The point cloud was then read into Pro/ENGINEER Wildfire – after which the rest of the design work and all the analysis was done within Pro/ENGINEER. Interactive Surface Design (ISDX) and Advanced Assembly (AAX) features were used to build the CAD model, and Pro/ENGINEER Mechanica was used for the thermal and structural analysis with FloEFD.Pro Concurrent CFD software was used for the aerodynamics.

The beauty of Concurrent CFD is that it works directly within the CAD system so everything is done within the one environment. The CAD geometry does not need to be exported and cleaned up for the analysis, it can be used as is, or simplified using Pro/E’s Publish Geometry feature whilst retaining all the model’s parametric features so design changes are carried out in the CAD tool on the native CAD geometry. Here’s an exploded image of a model Voxdale created.

Additional information is needed for the FloEFD.Pro analysis such as surface roughness information, plus the wheels need to be made to rotate and the ground move. Actually this makes the simulation better than most wind tunnel setups where it’s often impossible to achieve this on a full size car!

Once the model is built in the CAD tool, the opportunities to improve the design through analysis is really only limited by the designer’s imagination – specifically their ability to identify aspects of the design to improve and ask themselves the question “What if…?”, and changing the design accordingly to see how key performance parameters like aerodynamic drag change as a result.

Here are some of the flow trajectories and cut plots showing the flow over the whole car, and showing the air flow into the side pods
