Can anyone without a degree on air craft engineering or a doctorates degree on physics build a hovercraft? It may seem impossible. What most laymen and hobbyist dads do not know though is that even they can build their own hovercraft if they have the right hovercraft plans.
What it takes is to understand the basic principles of whatever you may be trying to solve. In understanding how to build a hovercraft, it will be easier if you know the principles behind it. Read on.
As far as its basic principles are concerned, hovercrafts do not differ much from how an air craft works. Although they may look like boats, it is being run via aero dynamics. It is defined as an amphibious vehicle lifted by pressurized air cushion and maneuvered by air throughst. Simply put, the hovercraft actually floats and glides on a smooth surface. There are four major parts in a hovercraft system that you should know.
Hovercraft Hull - The hull of the hovercraft is the part of the structure where you sit (or stand in some designs). This is the body of the hovercraft. How to build to build a hovercraft hull requires a bit of knowledge on what materials to use. The most common are ply wood, aluminum, plastic, and fiberglass. Notice that these materials are relatively lightweight. The hull should also be designed to include the principles of buoyancy. This is so that it floats automatically it water.
The Hovercraft Skirt - The skirting system is that flexible waterproof material installed around the hull. It got its name from its cross-section plan where it resembles a girls skirt. The skirt helps in pressurizing and controlling the air cushion thus giving the lift. It should also be designed stabilize the hovercrafts glide naturally. To know how to build a hovercraft, there are three types of skirting system to study. These are: (1) bag skirt; (2) jupe skirt; (3) segmented skirt.
A Hovercraft Propeller and Fan - The hovercraft is lifted by the air cushion caused by containing pressurized air beneath its hull. The air is provided by a fanning system strategically mounted in the hull. When the air is channeled from the atmosphere down to the bottom of the hull, the skirt temporarily traps it until it stabilizes a lift. Now that you know how the vehicle is lifted, its time to understand how to build a hovercraft fanning system.
What helps inflate the cushion and throughsts the speed of the craft is the fanning and propeller system. Another great use is for the propeller system to give that needed throughst. Some hovercrafts have powerful fans that can give both. In smaller types, they use separate systems for each purpose. If you have a design kit in how to build a hovercraft, look into this part of the plan. This is a bit technical although most design kits are made for easy use.
Engine of the Hovercraft - The last thing to know in how to build a hovercraft is to know what engine is to be used. The idea is to have a balanced weight to horsepower ratio. This means it should be lightweight but powerful enough to create a good stable lift and speed when gliding. The key point in engine efficiency is by its stroke cycle type. For small homemade hovercraft, you may use a 4-cycle engine, similar to the ones used for lawn mowers. Bigger and commercial hovercrafts use engines by cylinders.
