In my earlier days i got creative and built a 3 man hovercraft and a two man fuel injected Trike. This website is a collection of the build process i went through to achieve both those tasks.
The original website in general was written back in 2004-ish and for the most part of it has been left with the same wording as I had it back then, miss spellings and all :)
However nowadays I figured it was time to make it a little more user friendly. Back in the day I wrote the build website in HTML manually, but in this current day it looks ummm..... old :)
So recently I have tweaked the design and in some places, the wording, to be a little more relevant. I didn't go over board with the design keeping it simple and clean.
To begin Navigating:
- Click "start here" button above to start from the beginning of the build
- Or choose a category from the drop down menu above
- Or select from the menu at the top of the page
Anyway... let's get into it....
The Hovercraft was started in Mid October 2004, and I achieved my first test hover in one spot on 11th November 2005. The plans were purchased from ASV Australia and I have stuck to the plans up until the stage of mounting a duct, from that point onwards I'm working off the top of my head which could be classed as a scary thought.
So the main items I'm not sticking with in the plans are , Duct, rudders, length, width, steering, fan assembly and the motor
Hovercraft Specifications :
Length 3.52m (11`6") + extensions total 4 meters
Width 1.98m (6`5") + extensions total 2.14m
Height 1.30m (4`3")
- Total weight without payload
(max) 400Kg (881lbs), weighed on 23-Jan 06
Cushion pressure not sure fully about this yet either
- Empty hull weight -
(no motor or parts, just purely hull and duct) 140kg - weighed on 17th Oct 05
Performance (all these readings may vary from the original plans so they are a guideline for now)
Hover height 230mm (9")
Speed - max 100km/h (i've currently taken as far as 60km/h over water and that's it till i'm more confident in how it performs)
Speed cruise 50km/h
- Climbing ability
- Static 1 in 6
- Dynamic 1 in 3
Not sure, would be more than original plans because i extended and widened the craft
- None, relying on no hangover and good judgment
- Monocoque, Epoxy resin bonded and sealed plywood
- Extended segment, individually fed, Chip bag on rear material- I'm going to try "polyester Oxford"
