My Inflator Fan Pics
Here is some pics of my 8HP 30" Inflator Fan that separated on 9/24/2005 on my AM flight in Knoxville, Tennessee. I have seen two other fans disintegrate (Not Mine). One inflator fan was wood and used a cheap Dayton Fan Cage, and the cage did not hold the blade, it flew out of the cage about 75 feet. The second fan one I seen explode was a composite blade and it turned into a pile of plastic chips and threw shrapnel about 20 feet on both sides. You couldn't pay me to use a composite blade. After dissecting the fan, if you look at the front washer plate that the bolts are inserted into, you can see that 3 of bolts are about 1/2" to 3/4" shorter than they should be. So 3 out of 4 bolts sheared off and the 4th bolt fell out undamaged. I use a 30" 3 blade fan blade from Arrow Prop and a Briggs 8 HP Motor with the "Big Shaft" and even though I disagree with about everything in the world when it comes to Balloon Works Balloons, I use their 30" inflator fan cage because it is the toughest fan cage that I have ever seen. My only complaint is that the welds tend to come apart on the outer ends of the fan. But it is still a heck of a lot better than the Dayton Cages. I also used some Big Ass Black Heavy Duty wire ties to help hold the cage together in case of failure. It blew 3 of the wire ties off, yet all in all, it still held the cage together and contained the fan blade and no one was injured. This fan was checked out in May of 2005 and completely retorqued.
