New Materials For A Brighter Personal Hovercraft Future

The first big hovercraft was devised and constructed to carry passengers across the English channel, a fitting start for the country who invented the air cushioned concept vehicle. Of course, it wasn't too long before the military became interested in the possibilities, which is ironic as they were presented with a working model when it was first invented. The Navy didn't want it because it wasn't a ship. The Army had plenty of vehicles, some of them amphibious, and the Air Force were not interested in a craft that could only lift itself a few feet off the ground.

A long time after it's inception, the hovercraft started to become attractive to the leisure industry, particularly in recent years when new materials have allowed economic construction of small personal hovercraft. The new materials are stronger, cheaper and much more durable, making the production of smaller craft for racing and fun an obvious next turn for the industry. Racing hovercraft are very popular and have a superior power to weight ratio. They accelerate fast and can travel at up to 80 km an hour. Operation is very different from bikes, cars or even boats, so it's a very specialist activity to get involved in.

Hovercraft Materials and Construction

Hull construction has had a major re-think by designers. For one thing, the old way of using glass fiber just couldn't continue. The craft were certainly light but they were very rigid and fragile. If such an air cushioned craft happened to hit an obstacle with any kind of force, it would certainly split the hull. Depending on the size of the split, it would either have to be replaced or repaired by an expert, which can be very expensive according to the extent of the damage. New material scan really take a knock or two. Of course, they may get scuffed or dented, but they don't split, being fabricated from high density expanded plastics.

Hovercraft skirts are another important feature of these vehicles that have had a major overhaul in concept. Originally made from rip stop sail cloth, modern skirts are now constructed from Kevlar and neoprene coated cross lap material. The new materials are extremely difficult to tear by normal means but of courses it can happen. The new way of fabricating skirts is to mount them in sections, so that if one part is damaged, that small section can be changed without removing the whole skirt.

Personal Hovercraft Skirt Material

Once upon a time hovercraft skirt material was just an afterthought, something added to contain the air pressure generated by the lift propellers above the hull. Indeed, the first hovercraft were simple affairs that didn't need much design finesse to make them work. The other thing was that the variety of material just wasn't there in the early days of the industry. The toughest thing around was probably rip stop sail cloth, which was amply used for all manner and sizes of sailing boats. The material is called 'rip stop' because it does exactly that - the very structure of the material stop any tear form extending, which is achieved by laying different layers of fabric across each other.

In any piece of fabric or soft material made in one layer, a tear will likely promulgate and get progressively worse, if the force that caused it continues. Now imagine two or three layers of the same material bonded together at an angle. When a rip is started and extends one way in one layer of material, the next layer opposes it and it tends to go nowhere, unless of course the force applied is enormous. This is still the principle used in modern skirt fabrication for small personal hovercraft, but the materials are very different.

As well as the employment of new materials, the way in which the whole skirt assembly is created and attached has been radically revised. One manufacturer of leisure hovercraft gives a prize for a special test that they invite any member of the public to perform. A piece of their hovercraft skirt material is cut with a knife, so that each half can be gripped easily with the hands - hovercraft kits and plans. The challenge is simply that anyone succeeding to rip or tear the material any further than the cut will win a huge bottle of the best champagne. Admittedly not a fortune, but it does show considerable confidence in the material used for this use.

Present day personal hovercraft skirts are made from either Kevlar, which is the bullet proof fabric used by the military, or rip stop nylon covered in flexible neoprene. Even though the material is very tough, anything can be destroyed in the right circumstances and one manufacturer has come up with a way of minimizing the hassle of a damaged hovercraft skirt. The company has separated it into several sections, so that if one part is damaged at all, the whole thing doesn't have to be changed.

Check out multiple dealerships for the car you desire. Once you select which make and model you want, don't just stick to the closest lot.

It is illegal for a dealer ship to roll back the odometer on any car they sell. Even if they put a new motor in the car, it is still illegal. If you suspect that a dealer is not stating the correct mileage on a car, leave and shop elsewhere.
