Defense and Aerospace
Defense involves the research, development and service of military material, facilities and equipment. Aerospace is also involved in research, design, manufacture, operation and maintenance of vehicles moving through space and air. Aerospace has a multitude of military, industrial and commercial applications.

coz area is less thats y pressure is more
I don't know all of the definitions but to the molded rubber industry it means:
A molded rubber part might require a few ounces of uncured rubber compound to be put into the mold to cure and make that part. It is unrealistic and expensive to put all of the ingredients together to make a few ounces of the right mix to make a part. So, there are two possibilities: a). we purchase several hundred/thousand pounds of the correct uncured mix from a vendor who specializes in making "masterbatch" and portion off a few ounces at a time to make parts; or, b). we buy a large quantity of "masterbatch" which contains most of the ingredients of most of our parts. When we have a specific order, we take a portion of the masterbatch and mix in various special ingredients to make the masterbatch perform in ways required by the part, once it is molded and cured. Then the part is molded and cured. To make it simple, masterbatch is the big pile of raw goop from which little piles of goop are extracted for a job to make parts for the customer.
Difference between operating weight and dry operating weight of an aircraft?
OEW = DOEW + Catering Allowance + Flight attendents
How many Aerospace engineers are there?
More than the current number of Aerospace engineering jobs available. I know because I was one...
Are there any large factories in Louisiana?
Yes, Louisiana is home to several large factories, particularly in the petrochemical and manufacturing sectors. The state hosts numerous facilities along the Mississippi River, including oil refineries and chemical plants, due to its strategic location and access to the Gulf of Mexico. Major companies like Dow Chemical and BASF operate significant manufacturing plants in the region, contributing to the state's economy. Additionally, Louisiana has a growing presence in other industries such as food processing and shipbuilding.
Why would pure Beryllium make a very poor aerospace building material?
- brittle
- very toxic
However several early missiles used beryllium heat-sink heat shields on their warheads,before composite ablative heat shields were developed.
What is the full form of RTB in Contract between buyer and Original Equipment Manufacturer?
In the context of contracts between a buyer and an Original Equipment Manufacturer (OEM), RTB stands for "Reason to Believe." It refers to the justifications or evidence that support a buyer's confidence in the OEM's ability to deliver quality products or services. This concept is crucial for establishing trust and ensuring that the buyer's expectations are met throughout the contractual relationship.
Aerospace law is a legal field that governs activities related to airspace and outer space. It covers regulations concerning air traffic management, space exploration, satellite operations, and international agreements to ensure peaceful uses of outer space. Aerospace law also deals with liability issues, environmental concerns, and intellectual property rights in the aerospace industry.

In general, land mines consist of two parts: the trigger (or detonator) mechanism, and the warhead.
Trigger mechanism can be one of three forms:
- Command detonators - some form of external control sends a signal to landmine telling it to detonate. Examples are the trigger grip of the US Claymore mine, cellphone triggers of many IEDs in Iraq, or mines tied to centralize sophisticated sensor packages. Simple tripwire mines are also "command detonated" mines.
- Contact fuses - pressure on or near the mine causes the fuse to be driven into the ignition mechanism, detonating the mine. Tilt sensors (those that detect a change in the level of the mine) are a form of contact fuse. All of these fuses drive small spike into a pyrotechnic trigger to start the explosion. The amount of pressure (or tilt) required to set off the mine varies according to the exact trigger mechanism used.
- Magnetic influence - the mine trigger detects a disturbance in the magnetic field in the area caused by a large metallic object.
The vast majority of mines use the second form of trigger.
The warhead of the mine varies considerably, according to the type of target the mine was designed to attack.
- Anti-personnel mines generally consist of a small amount of explosive coupled with some sort of fragmentation material (small metal spheres, sharp metal or ceramic shards, junk metal, nails, etc.). The idea is to fill the "kill zone" with a large amount of small fragments, which can kill or wound a much larger number of people than the same amount of explosive material could.
- Anti-vehicle mines contain a much larger explosive charge, to produce a large shock wave which can damage vehicles.
- Anti-tank mines usually contain an Explosively Shaped Penetrator - this consists of a specially-shaped explosive charge, with a metal sheet covering the end towards the target. The explosion forces this sheet into a dagger-like form, which will penetrate heavy armor much better than a normal explosion.

In North America mostly Boeing and Air Bus even though Air Bus is located in France. McDonald Douglas used to be one but it went bankrupt a few years ago and Boeing bought it so now it is called McDonald Douglas Boeing.
How to start up a call center?
I am talking about a small call center. You need an office,14 to 15 computers with desks and chairs, broadband routers, telephone sets with each computer and a broadband connection. You just have to contact a company and ask them that you want to sell their products and if they allow you, they'll give you a id of their and you'll place sales on that portal.
There are some services that will set up, and run the call center for you. Skilled people , right technology and well defined processes

- To reduce Wastage
- To implement FIFO inventory control
- To improve inventory tracking
- To increase productivity
- To improve Storage Space Utilization
- To improve Inventory Accuracy
The Boeing Company in the 1910's was just being founded by William E. Boeing. In 1916 William Boeing and Captain George Westervelt of the United States Navy were in designing of Boeing's first plane: Boeing Model 1. This aircraft was first flown on June 15th, 1916.
How do you run formal meetings?
By following the formal meeting procedures established by the project or company having the meeting. Been to thousands of them over my 30 year career.
