The technology behind water cars otherwise known as amphibious vehicles had never been an easy one. It has to do with principles of flotations and motions put together. When engineers came up with the idea of water cars in 1770, the invention was credited to Prince Raimondo who built the first amphibious carriage and Samuel Bentham whose design was built in 1787, all these engineers actually knew it is very possible. However, the possible technical problems remained how leaking can be prevented and the floating possibilities of such vehicle to reduce the risk of sinking in water when faced with storm or other negative forces.
By definition, or are vehicles meant to run on land and on water. The vehicles can run at full speed on land like conventional and still have the ability to move into the water with the loads in it and run on the water like a or as the ship would do.
Ever since its invention in 1770, the technology has not become popular even though it was invented years ago like other existing technologies and the reason is that the use of such vehicle has not become a necessity to civilians but to the it is a different thing as the vehicle was seen as a good idea that can help increase the of the and enhance their operations in both land and water.
Amphibious vehicles or water cars meant for civilian use have been classified to include; water power bicycles and bikes, amphibious speed cars, water buses, water trucks, and land boats, etc. these vehicles can carry a good amount of load or humans and run smoothly on land and water and vice versa.
The use of such vehicles has become an option for those living close to waterfronts due to the possibility of driving them directly from home into the water, run through the waterways to their destination and return home with the vehicle without packing it at the waterfront which is an important aspect in securing their property that cannot be obtainable in an ordinary boats or ships.
Despite the scarce use, the had earlier from its invention dominated the civilians in the use of the . Some of the popular made so far belong to the or can be said that they were meant for use, some examples of such vehicles include;
LARC-V5 amphibious cargo vehicles,
Jet propelled amphibious boats like the French VAB,
Amphibious alligator tug, water land rover,
And LVT buffalos in Canada, etc.
The military has been developing and using these vehicles to aid their operations since its invention. However, the sizes, brand, and quality of the have been found to be according to the type of operation and nature. Also, from different countries had been found to develop their own based on their own specifications. The recent research also showed that almost all the modern commercial vehicles including armored personnel carriers, , and warfare ships, etc. were built with amphibious capabilities.
DISADVANTAGES OF /AMPHIBIOUS VEHICLES
Despite the advantages they offer, such vehicles had been found to possess the following setbacks:
- Some of the have slow speed while on water because of the resistance created by the below it.
- They may have limitations as to the depth of water they can be used.
- There is a greater risk of sinking than conventional boats made with because they are bulky, bears and made with metals.
- They cannot be used to chase conventional boats on the water, meaning they may not be able to chase criminals operating in waterways.
- They may be consuming more fuel while on water than normal boats due to their weight and slow speed.
- They may not be good for water that has storm condition or severe wind, except if the water depth is very shallow.
- If the propelling gets damaged while on water, that may become a serious problem.
ADVANTAGES OF /AMPHIBIOUS VEHICLES
Despite all the setbacks, the have the following advantages:
- They enhance speed operations on land and water.
- The vehicles are usually strong to withstand different weather conditions.
- They are usually equipped with long-range guns, etc. for distance operations.
- Majority of them are .
- They can carry a substantial amount of loads including personnel.
- They can be highly resistant to water leakages at their base than conventional boats.
- When hit by a solid object below the water, it leaves no damage to the vehicle body and the impact may be low due to their bulky nature.
Though the above advantages and disadvantages were generalized, some may be omitted or added depending on the type of the . Research showed that some of the had been to operate more efficiently on water than land, while some were made to operate more efficiently on land than water. Any of the above choices of a design was based on the supposed functions of the so in such case, the disadvantages and advantages may vary.
Light like the US PT-76, can operate both on land and in water. It is an equipped with sets of hydro . The question of having a vehicle that can completely be inside water or fully covered with water like and still is moving or carry out its operations may not be answered currently, though possibly more information will be gathered about such before its features publication.
