the building process of airplanes and trains

Modern technologies have allowed us to travel further and faster than ever before. We can tackle almost any terrain and transcend our physical limitations. For instance, planes allow us to fly above the clouds and cross oceans in a matter of hours. These trips used to take weeks or even months with ships. Trains can transport people and goods efficiently along tracks that can stretch hundreds of miles. Tanks are the ultimate all-terrain vehicles that can cross desserts and hills. They are built to withstand impact coming from all sides. Let us look at how these vehicles are made step-by-step.























The Design Process


Everything starts with the concept. Designers pick a goal and set about finding ways to reach it. This might be an increase in efficiency, in which case they will probably try to minimize drag and reduce weight. They will flesh this out until they come up with a detailed design in 3D with all of the components from wheels to engines to propshaft universal joint. While intial concepts tend to be ambitious, the final design will generally be more practical because of physical and budgetary constraints. They can run computer simulations to see how their creations may perform in ideal conditions.


Testing the Prototypes


Once they are fully satisfied with the design, they can move on to building a few prototypes. The vehicle can finally leap out from the computer screen into the real world. Stress tests can be performed to see if the prototype can handle the load and abuse that it will be facing during regular use. Other types of analysis will be done to make sure that everything is dialed in. It is at this stage when unforeseen flaws and complications are likely to be identified. The engineers will try to come up with solutions. They will change the design or materials if necessary.


Mass Manufacturing


The last stage of the process is the actual manufacturing of the vehicle's retail version. If the last prototypes have satisfied all of the standards, then it will be possible to finally make these in large quantities for selling. Demand will be gauged through preliminary marketing efforts. Manufacturers will take pre-orders and deliver the finished product after an agreed period. Most of the time, buyers will not see the vehicles until they are delivered. A great deal of trust is placed on the company to create the items as specified. They will continue to gather feedback after deployment and can make further changes to the design to fix persistent issues, if any.


Conclusion


This entire process can take many years. Massive resources are poured into the research and development of new models. Repeated tests are necessary to ensure compliance with all industry standards and regulations. Failure to meet these standards can result in costly recalls and fines. If safety is compromised, then the company may be sued for millions by those affected. They have quality control systems in place every step of the way to make sure that everything is in order.
