Getting A Design Plan For Building A Hovercraft That Works

Aero dynamics is the major principle behind a hovercraft. This is similar and can also be attributed to fluid mechanics in engineering. Although the hovercraft was designed to glide primarily in water, it behaves more like an aircraft vehicle. Its ability to function and operate fully relies so much on the air pressure simulated by its fan. This innovative engineering idea and application is what makes a plan for building a hovercraft works.
This amphibious vehicle can come in many designs. Some of them can carry a greater mass of people or load and usually used for commercial purposes. Other are designed for singular loads. Most of them look weird and mysterious. And as mentioned above, even when they qualify as boats, a hovercraft behaves like aircrafts. If you have a plan for building a hovercraft, simply understand the principle.
- A hovercraft’s lift depends on its overall size and weight. But if you’re designing a plan for building a hovercraft, your minimum cushion clearance should not be lesser than 6 inches. This means that when its maximum load is in place, the pressurized air below should be able to contain a lift of that much. This is the minimum because in cases when you need to glide in land, stones in the soil that can affect the smoothness of its glide.
- Cushion and Air Pressure - This is generated by a fanning system powerful enough to create the lift. In designing a plan for building a hovercraft, make sure that the pressure must be proportionately amendable to the weight of the hovercraft. If you hope to build to carry one person only, then use fans that exert the appropriate pressure required. The concept should follow that the total weight a hovercraft can lift is its bottom surface area multiplied by its cushion pressure. This should tell you the type of fans to use in relation to its horsepower.
- Skirting System for the Hovercraft - This is one part in your design plan for building a hovercraft that is unique on its own. Its purpose is to somewhat trap the air coming from the fan, allowing only a regulated release of air. This concept to manipulate air dynamics creates the cushion required to lift the hovercraft.
- Hovercraft’s Thrust and Air Drag - Just like aircrafts and automobiles, your hovercraft should use its applied science on thrust and air drag too. A plan for building a hovercraft should include where to place the propellers for creating the thrust. Windshields or similar installations are required for air drag purposes. Like the fan used for air cushion, the horsepower for your propellers should determine how fast your hovercraft can go. And while at it, the air drag design is considered to reduce the air friction for a smoother sail. Some hovercrafts use one powerful fanning system to support both cushion and thrust.
- Hovercraft’s Steering System - Imagine how a horseback rider maneuvers a horse. This principle is similar to how the hovercraft is steered. In your plan for building a hovercraft, you need a system of rudders placed behind the propellers with handlebars to control it. Another method would be to allow weight displacement of your body. The latter can be tricky and requires a lot of practice to perfect your hovercraft gliding experience.
