Key Points To Consider When Buying A Personal Hovercraft

This new industry is taking the outdoor sporting world by storm and more companies are designing better models every week it seems. As it is still a fledgling industry, you can find huge differences in quality in the market place, so what are the things to look for before answering those hovercraft for sale ads? Nobody wants a pig in a poke, and buying a personal hovercraft that is unsafe or doesn't perform is worse than useless. In act, it could be downright dangerous, especially if your are a family man with kids. Some things are obvious, for example - a racing craft is inherently more unstable than a slower leisure hovercraft.



Before going to see any particular air cushioned vehicle, first check over the specs to make sure it will suit your needs? How many seats do you need? Is your top concern speed, fun or safety? All vehicles have a combination of all three in order to maximize your fun. The engine noise levels in decibels should be recorded at various throttles, and it may be recommended to wear ear protection - not too sporty, but hearing degrades pretty fast when wind is rushing past them, and also a loud engine is whining away close by. Another thing to look for and ask about it the problem known as 'plow in'. this occurs in choppy seas when a wave hits the bow causing it to dip into the water with dangerous consequences.

The skirt should be manufactured from very tough and durable material, such as rip-stop sail cloth with a rubberized or Neoprene coating - check it out this article. One company actually challenge prospective customers to tear their skirt fabric, so it's a good indication that it's tough enough. The skirt should be attached in sections, rather than one piece. Sounds strange, but imagine hitting a rock and tearing a one piece skirt. The whole would have to be changed, which is very expensive. You wouldn't be carrying one, so the day would be ruined as well.

Finally, so and see the hovercraft you want to buy and give the once over. All manufacturers and dealers will let you have a go, and it takes just 5 minutes to learn how to operate one. Does the machine look good? If it seems robust, then that's a god indication. It's hard to hide shoddy workmanship. Also, you can feel the stability once it's moving along which will give you confidence to purchase. You need confidence, because these things now cost about the same a car for the 6 seat hovercraft and it's a lot of money to shell out if it isn't exactly what you want.

Hovercraft Construction Materials

Designing and building a hovercraft

Building a hovercraft isn't the easiest of tasks as there are a number of essential design and construction principles to adhere to. But with some good guidelines or instructions, some handiness with tools, time and patience, success is assured. Of course you can always buy one instead and the price of small hovercraft are coming down all the time.



The basic principle

The basic principle of an air cushion is that if you lift an object off the ground using air you reduce the force needed to move the object. Because the object is no longer in contact with the ground the friction this causes (surface friction) is reduced, making it easier to move the object. This also implies that the smoother the surface the less the friction. This is also true. Uneven surfaces with rocks and other obstacles can significantly slow down or even stop and damage an air cushion vehicle if the chamber containing the air cushion (the plenum chamber) was made of rigid materials.Hence the use of a flexible skirt and the need for sufficient lift. This allows the craft to pass over (smaller) rocks and other uneven terrain obstacles without (too much) trouble or damage or slowing down.

The basic parts

That said with a hovercraft we can identify four basic construction necessities - 1) the hull, below which is attached the skirt system, 2) the carriage or cabin part which needs to hold the passenger(s), crew or freight, 3) a propulsion system to move the craft, and 4) the lift system to feed air into the plenum chamber below the craft in order to create the air cushion.Some hovercraft use a single engine system to provide both the air for the plenum chamber and propulsion. The difficulty in using one engine is to provide optimal efficiency for both systems, dividing the power for propulsion as well as for the fan to produce enough air for the lift. Many modern air cushion vehicles use separate systems for air and propulsion. But advances in engines have made it possible to choose between one and two engine systems, especially for smaller, recreational hovercraft. Bigger, industrial, commercial or military hovercraft can have anywhere up to eight engines for propulsion and lift.

Power-to-weight ratio

Although an air cushion vehicle does not require the critical power-to-weight ratio precision as does an airplane in order for it to still operate, it is nonetheless necessary to consider the power-to-weight ratio at the design stage of an air cushion vehicle, rather than find out later that there isn't enough power to lift or move the craft. The power-to-weight ratio determines in large part the amount of ground clearance between the skirt and the ground surface. The greater this ground clearance the more efficiently the propulsion system operates. That is not to say that the higher the hovercraft lifts into the air the better. Lifting it too high will cause instability. Such is the power of the lift that even a severely overloaded and miscalculated power-to-weight ratio hovercraft construction will still work, but it is far from ideal.

Military Use Of Hovercraft

Its well known that any scientific development or discovery is quickly exploited for military purposes, and the hovercraft industry is not different from any other in that respect. In general, an air cushioned vehicle cannot change direction very quickly, so would be no good in a combat situation for example, but the fact that it rides on a cushion of air without touching the surface of the ground raises very interesting possibilities.

Imagine a military commander needing to transport men and equipment many miles over marshy terrain, sometimes hard ground, sometimes shallow water and in places a sticky mud. The variety of surface conditions requires a mode of transport that isn't land based, nor marine in nature. A hovercraft simply glides over any surface and the flatter the better. Water, mud, slippery ice and snow are no obstacles to a hovercraft.

Although the principle of using a contained air pressure as a means of transport was known for decades, it was mostly seen as a novelty having no real commercial value. After all, steering the craft was difficult. It couldn't stop very quickly, or manoeuvre tight corners, but then neither could large ships. In fact, sea travel was the most interesting early application of ACVs, both for private commerce and the military.

After World War 2, Russian hovercraft manufacturers built an enormous craft, possibly still the largest in the world, which could carry hundreds of tons of men and machines. Russia is of course a vast country with plains and ice which are easy to traverse using a vehicle that hovers just above the surface. It's not how nimble the craft is, but it's carrying capacity for this type of work. It doesn't get bogged down because it has no wheels. If it cannot stop quickly then it's relatively easy to allow more time to stop, it's a simple as that! A bit of planning will ensure that the terrain to be hovered over has plenty of space for turning.

The engines used for thrust and lift are of course much bigger than a comparable size commercial hovercraft. In fact, the supersized model has many engines. If you think about it, military vehicles of all kinds are always much heavier than regular machines, due to the fact they they are intended for rough and frequent use. It's also true that military hovercraft maintenance schedules are second to none, so that the motors are always in tip-top condition.

Specialist training is required to pilot such a craft. It isn't an aircraft, marine craft or land vehicle therefore a different approach has to be taken to controlling direction and speed.

Motorcycles Vs Scooters

Motorcycles and scooters are handy especially during traffic snarl-ups in town. Also, the use of these machines gives the advantage of low fuel consumption compared to other machines doing the same job. You might be wondering which one of them you would prefer during shopping. They exhibit vast similarities and differences which are both factors to be considered during shopping. Also, they have different benefits to the riders, and your choice will depend greatly on your taste. Below is the comparison of the two machines.

Differences

Ease of riding

If you want to navigate the roads with ease, then scooters are your best bet. This is due to the varying types of transmissions on each machine. Unlike in scooters where you get to enjoy the automatic transmission, motorcycle riders have to do this manually by operating the machine's manual transmission while at the same time using a clutch. Also, a bike is heavier compared to a scooter. As such, maneuvering becomes a task and can me much harder to learn to ride.

Step through frame

In motorcycles, there is no step through frame. Therefore, you will need to assume the position of a horse rider. On the other hand, scooters have the frame. So you just sit and place your legs on the board below, and you are ready to go. When you are getting on the scooter, you dont move your leg over the bike since there is a space to get your leg through to the other side, unlike motorcycles.

Acceleration

Motorcycle engines are larger and stronger than the scooter engines. Therefore, its acceleration speed is higher than the acceleration speed of the scooter. Some larger scooter models can, however, exhibit relatively higher acceleration than smaller motorcycles. Scooters are much lighter than the motorbikes. So, when you try to accelerate faster, you jeopardize your safety since the scooter is less stable.

Similarities

Street legal

By being street legal, both machines have features that are coherent with traffic rules like headlights, rear light, and the mirrors. These functions are handy in traffic to avoid unnecessary inconvenience to other motorists.

Fuel consumption

The scooter and the motorcycle both have the feature of consuming less fuel compared to other machines that could serve the same purpose. As such, they are excellent 'fuel economizers.

With the above comparison, you can now make a choice. The selection of either the motorcycle or a scooter will depend on several factors including the purpose for which you are purchasing the machine as well as the price.



Procedure For Replacing A New Automobile Battery.

When detached, you will want to make sure that the terminals do not come into contact with another surface. Upon taking off attempt to shield them using a non conductive item.

Most vehicle battery terminals use 8mm,10 mm,13 mm nuts these can in most cases be undone with a spanner.

Disconnecting the terminals.

(Negative Terminal 1st).

The primary terminal to remove should be the negative which has the - (minus) sign on it or the battery area itself.

(Positive Terminal 2nd).

Then remove the positive terminal that has the + (plus) mark on it or the battery itself.

After you have the terminals unfastened transfer them out of the way so you have easy access to remove the battery (make certain not to allow the unhitched terminals contact anything at all). Various vehicle batteries additionally have a gas venting line fastened, this needs to be unfastened before removal.

Step 6.

Hooking up the new vehicle battery.

Make sure that the battery location is clear and clean, then verify the battery terminals are not in the way and place the vehicle battery back into location.

(Attach the Positive Terminal 1st).

Remove the non-conductive shield from the positive battery terminal and hook on to the positive terminal on the battery. Make certain it is secure and then re tighten.

(Hook up the Negative Terminal 2nd).

Take away the non-conductive cover from the negative battery terminal and attach to the negative terminal on the battery. Make certain to secure and afterwards .

In the event that you have a battery gas ventilation pipe reconnect to the new battery.

Step 7.

Detach the external power/battery memory saver.

(Do Not Turn On on Or Start The New car With The Battery Memory Saver Still Connected).

When your new auto battery is connected you may now disconnect the battery memory saver unit.

Step 8.

What Are The Various Benefits Of Getting A Used Vehicle When Compared To A New Automobile

What are the various benefits of buying a pre-owned vehicle when compared with a brand new car?

It's the perfect time for you to buy a new vehicle and you may be thinking which would be the wisest purchase, a pre-owned automobile or a brand new one. Even though 100% brand new vehicles have their own allure there are several advantages of opting for a second-hand automobile. Most car salesmen would actually attempt to offer you a brand new automobile since these individuals earn more money especially if it is a top of the line brand and model.

However if you've got a choice of second-hand vehicles to pick from then be certain to think twice about purchasing a new vehicle. Before we consider some of the most important factors of picking used automobiles it really is imperative to point out the one detail that you must have in mind is and that one detail is how the vehicle has been maintained previously. You want a vehicle that was owned previously by someone with a record of maintaining it.

The first benefit of buying a pre-owned automobile is the obvious fact that you're going to spend a lot less which ranks number one, two and three. Though most people generally don't realize it, the cash difference, on average, between a second-hand and a new car is about twenty grand. In this economy where most individuals typically don't possess that sort of extra money, it makes no sense to use up that amount of cash specially when you can take advantage of exactly the same characteristics with a second-hand vehicle.

Although it's accurate that the interest rates on second-hand vehicles are larger, the actual gap between the two is minial. On a new vehicle you would get around four percent whereas on a new car you'd get more or less 4.99%.

A used automobile obviously has a track record and you know of course that an individual has used it and that it functions well. Provided that you receive a maintenance record to show that the car was serviced regularly you're going to be all right and have a better comfort levell.

A second-hand vehicle has lesser depreciation when compared with a brand new car. Once you purchase and then take a car from a showroom you right away lose about twenty five percent of its original price. That is a great deal of cash lost if you give it some thought. In the event you purchase a pre-owned automobile, however, it'll depreciate in actual value but then not that drastically year over year. If you ever put it up for sale after a short time you would secure a large amount of your investment back.

You don't pay out taxes when it comes to used automobiles at all. That is something that a lot of states don't make known to the general public. Learn exactly how much tax you have to pay on a used automobile in your own state of residence and see the amount of money you're going to be saving.

The registration expenses for cars decreases year after year, although for new cars the fees are really high initially. If you get a pre-owned vehicle you will not pay out that much in registration fees plus they will fall year after year taking less out of your bank account. If your decision is to go with a pre-owned vehicle, one place you can't go wrong is buying used cars in Elkhart from the Lochmandy Auto Group. Their history spanning nearly one hundred years stands alone when it comes to taking care of their customers.

Whenever you get a new automobile you'd be getting quite a lot of add-ons or accessories that you typically don't need to have. Car sellers are smart and so they desire to make the most money they can out of you. Generally, they do that easily by including add-ons or accessories to brand new cars and then charging you for these add-ons. You don't have to pay additional for things that you simply don't require and as a result of going with a used car, you avoid these added costs and save more money.

Think again before buying a new car as a second-hand car would actually get you where you wished to go on time and in the same comfortable ride.
