Theoretical:
The brushless lift motor uses 3 ampere to lift the whole design
The skirt of the design should be 2 inches tall
The distance between the frame plates can be 1,2 inch
There are 2 propellers of thesame dimensions needed
Most favorable:
The brushless lift motor uses 1 ampere to lift the whole design
The skirt of the design should be 1,8 inches tall
The distance between the frame plates can be 1,1 inch
There are 2 propellers of thesame dimensions needed
Practical:
There brushless lift motor uses 2 ampere to lift the whole design
The skirt of the design should be 4,5 inches tall
The distance between the frame plates can be 1,6 inch
There is 1 lefthanded propeller and one right handed propeller with turned engine needed
We can conclude that there is always a efficiency between theoretical, practical and most favorable performances. Our conclusion in this project is:
The skirt needs to be taller then expected ( which only looks better in the design which was not expected )
The brushless motor lift motor uses less elektrical energy then expected
The distance between the plates cannot be achieved when there is no mounting door in the upper-plate
There are 2 different types of trust propellers needed, an accesoire as third propeller cannot be done by this.
The reasons why the calculations didn't turn out to fit are:
The brushless motor was calculated on pure weights. So that doesn't include all of the elements that make the hovercraft lift. Because of the water the hovercraft didn't need that much power.
The skirt was designed on its roundings, wat we didn't knew was that they need to be blown up for propper work.
The plates can't be 1 inch close to eachother. This because they also need to be mounted as one.
The 2 propellers are slapping wind sideways. Thats why they can't be thesame.
So u see. Theoretical there can always be a certain kind of information missing.
That's why its always good to test it anyways, no matter how surten you are.
