Hi and thank You for visiting my blog.

This blog is about my professional work, projects I have been working on, and some funny and interesting things about mechanical engineers. On these pages You can find some of my projects, as I work for army and I am not able to enclose all projects I have been working on.

My most recent designs You can find in posts below.

For more interesting projects You can follow labels, such as:
- aircraft engine blades

- aircraft parts

- wind tunnel models


You can download some of my models, posts with files for download are labeled free model download.

or You can go to INDEX page and search through list of all projects on this blog.

Info about me is on ABOUT ME page, where You can see my professional CV and some info about my skills and professional knowledge.

For all questions about my work, projects, blog or job offers contact me over e-mail or Skype. E-mail form and Skype Add Me link are on CONTACT ME page.

For those who are interested in learning new stuff about Siemens NX program I made NX TUTORIALS page, where I will post some tips and tricks about how to use NX more efficiently.

Jokes about engineers

Water in the Glass

To the optimist, the glass is half full.
To the pessimist, the glass is half empty.
To the engineer, the glass is twice as big as it needs to be.

Arguing with an Engineer

Arguing with an engineer is a lot like wrestling in the mud with a pig. After a few hours, you realize that he likes it

Human Anatomy

Three engineering students were gathered together discussing the possible designers of the human body. One said, "It was a mechanical engineer. Just look at all the joints."

Another said, "No, it was an electrical engineer. The nervous system has many thousands of electrical connections."

The last said, "Actually it was a civil engineer. Who else would run a toxic waste pipeline through a recreational area?"

 If it Ain't Broke

"Normal people believe that if it ain't broke, don't fix it.
Engineers believe that if it ain't broke, it doesn't have enough features yet."

Scott Adams, The Dilbert Principle

Coming out of Retirement

There was an engineer who had an exceptional gift for fixing all things mechanical. After serving his company loyally for over 30 years, he happily retired. Several years later the company contacted him regarding a seemingly impossible problem they were having with one of their multi-million dollar machines. They had tried everything and everyone else to get the machine to work but to no avail.

In desperation, they called on the retired engineer who had solved so many of their problems in the past. The engineer reluctantly took the challenge. He spent a day studying the huge machine. Finally, at the end of the day, he marked a small "x" in chalk on a particular component of the machine and said, "This is where your problem is." The part was replaced and the machine worked perfectly again. The company received a bill for $50,000 from the engineer for his service. They demanded an itemized accounting of his charges.

The engineer responded briefly: One chalk mark $1; Knowing where to put it $49,999.

A Geologist and an Engineer

A Geologist and an engineer are sitting next to each other on a long flight from LA to NY. The Geologist leans over to the Engineer and asks if he would like to play a fun game. The Engineer just wants to take a nap, so he politely declines and rolls over to the window to catch a few winks.
The Geologist persists and explains that the game is real easy and a lotta fun. He explains, "I ask you a question, and if you don't know the answer, you pay me $5. Then you ask me a question, and if I don't know the answer, I'll pay you $5." Again, the Engineer politely declines and tries to get to sleep. The Geologist now somewhat agitated, says, "OK, if you don't know the answer you pay me $5, and if I don't know the answer, I'll pay you $50!"

This catches the Engineer's attention, and he sees no end to this torment unless he plays, so he agrees to the game. The Geologist asks the first question. "What's the distance from the Earth to the moon?"

The Engineer doesn't say a word, but reaches into his wallet, pulls out a five dollar bill and hands it to the Geologist.

Now, it's the Engineer's turn. He asks the Geologist, "What goes up a hill with three legs, and comes down on four?" The Geologist looks up at him with a puzzled look. He takes out his laptop computer and searches all of his references. He taps into the Airphone with his modem and searches the net and the Library of Congress. Frustrated, he sends e-mail to his co-workers -- all to no avail.

After about an hour, he wakes the Engineer and hands him $50. The Engineer politely takes the $50 and turns away to try to get back to sleep.

The Geologist is more than a little miffed, shakes the Engineer and asks, "Well, so what's the answer?"

Without a word, the Engineer reaches into his wallet, hands the Geologist $5, and turns away to get back to sleep.


An engineer and a lawyer were recently fishing in the Caribbean. The fishing was outstanding and they got to talking about their vacations.

The lawyer said, "I'm here because my house burned down, and everything I owned was destroyed by the blazing fire. The insurance company paid for everything."

That's quite a coincidence," said the engineer. "I'm here because my house and all my belongings were destroyed by a raging flood, and my insurance company also paid for everything."

The puzzled lawyer asked, "How DO you start a flood?"

Oldest profession

A physician, a civil engineer, and a computer scientist were arguing about what was the oldest profession in the world.

The physician remarked, "Well, in the Bible, it says that God created Eve from a rib taken out of Adam. This clearly required surgery, and so I can rightly claim that mine is the oldest profession in the world."

The civil engineer interrupted, and said, "But even earlier in the book of Genesis, it states that God created the order of the heavens and the earth from out of the chaos. This was the first and certainly the most spectacular application of civil engineering. Therefore, fair doctor, you are wrong: mine is the oldest profession in the world."

The computer scientist leaned back in her chair, smiled, and then said confidently, "Ah, but who do you think created the chaos?"

Engineer and frog

A guy was crossing a road one day, when a frog called out to him and said, "If you kiss me, I'll turn into a beautiful princess." He bent over, picked up the frog and put it in his pocket.

The frog spoke up again and said, "If you kiss me and turn me back into a beautiful princess, I will stay with you for one week." The guy took the frog out of his pocket, smiled at it and returned it to his pocket.

The frog then cried out, "If you kiss me and turn me back into a princess, I'll stay with you and do ANYTHING you want." Again the guy took the frog out, smiled at it and put it back into his pocket.

Finally, the frog asked, "What is the matter? I have told you that I'm a beautiful princess, and that I'll stay with you for a week and do anything you want. Why won't you kiss me?" The guy said, "Look, I'm an engineer. I don't have time for a girlfriend. But, a talking frog is cool."

    To the Designer, the glass was correct on CAD.
