Hovercraft Design: Calculating Diameter Holes in Hull

[eng.m.mostafaa]

welcom every boddy
i want to ask u alittile about hovercraft design
1-i want to ask how can i calcoulate the dimaeter holes in hull for cushion the hovercraft
thank u :!)

Ask yourself the following sort of questions:

What are the holes for? What needs to flow through them? How much stuff is going to flow through them? How fast will this stuff be going? What pressure will it be at?

I have built a hovercraft and I had approximatley 10: 1 inch by 1 inch holes(this worked well for my desighn) which was a 4 foot by 3 foot square with a donut skirt...this also might help http://www.amasci.com/amateur/hovercft.html

hi
i am a new user
if you have any fomulation about holl design and number of holes on it can help me?
we have dsign a 2*3 hull around hover but we no idea about the hieght and width of it?

Hello there,

Calculating the diameter holes in the hull for cushioning a hovercraft can be a complex process, as it involves considering various factors such as the weight of the hovercraft, the desired cushioning height, and the type of material used for the cushioning. However, a general approach to calculating the diameter holes would be to first determine the total weight of the hovercraft, including its cargo and passengers. This will give you an idea of the amount of air needed to lift the hovercraft.

Next, you will need to determine the desired cushioning height, which is the distance between the bottom of the hull and the surface it hovers over. This will depend on the terrain and conditions the hovercraft will be operating in.

Once you have these two values, you can use a formula such as the Archimedes' principle to calculate the volume of air needed to lift the hovercraft. This volume will then help you determine the diameter of the holes needed in the hull to allow the right amount of air to flow through and create the necessary cushioning.

It is important to keep in mind that the material used for the cushioning also plays a role in the calculation. For example, if you are using a more rigid material, you may need larger holes to allow for enough air to flow through. On the other hand, a more flexible material may require smaller holes.

I hope this information helps you in your hovercraft design. If you have any further questions, please feel free to ask. Best of luck!
