Discussion Overview

The discussion revolves around the design of hovercraft, specifically focusing on calculating the diameter and number of holes in the hull necessary for creating an effective air cushion. Participants explore various factors influencing hole design, including flow requirements and dimensions.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested, Homework-related

Main Points Raised

  • One participant inquires about the calculation of hole diameters in the hull for hovercraft design.
  • Another participant suggests considering the purpose of the holes, the flow requirements, the volume of air needed, the speed of airflow, and the pressure conditions.
  • A participant shares personal experience, stating that a design with approximately ten 1-inch by 1-inch holes worked well for their 4-foot by 3-foot hovercraft with a donut skirt.
  • A new user requests formulations or guidelines for hole design and dimensions for a 2x3 hull, indicating uncertainty about height and width.

Areas of Agreement / Disagreement

Participants express various considerations regarding hole design, but there is no consensus on specific calculations or formulations. Multiple viewpoints and uncertainties remain regarding the optimal design parameters.

Contextual Notes

Participants mention various factors that could influence hole design, but specific assumptions and calculations are not provided. The discussion lacks definitive mathematical formulations or agreed-upon design criteria.

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?
my mail is "ahe1367@gmail.com"
thanks
