It's a simple vector algebra problem - you have the horizontal (airspeed) and vertical (altitude) component of the triangle and then you just need to calculate the angle of the sight. Drop the flour bomb when the target is in sight.

What about air friction? Vertical air speed will increase until you hit terminal velocity due to air friction, while forward speed will continue to diminish to zero due to friction.

You are right, hence the altitude and area of target zone is important as to whether the triangle approximation is sufficient. If we want to make a 1 square meter target from 10,000 feet, then all kinds of new factors need to be accounted for...

Four legged or 3 big wheels ?

I'll probably be there on Saturday.

Comin' from Wolfebora. Come every yeaa to the show and Valdez.

Aim all you want but i did the flour bombing several years ago in Juneau and when you dropped the bag out the window they got caught in the wing vortices and went up, around over and started to fall anywhere but where you thought they would.

Full five pound bags would work a lot better, what they gave us was a lunch size brown paper bag with a cup of flour in it.

Lots of them landed clear off the apron, hundreds of feet off target.

A million years ago, our flight department would hold annual competitions. Kind of like Valdez, but without the talent. The bomb drop used small plastic bags filled with a couple pounds of sand. Lots of calculations were made on drop points. What was not considered was the deformation of the bag due to initial velocity and the resulting rapid loss of forward motion.

Since nobody in previous years had ever even come close to the target I figured it would be safe to volunteer my auto as a target. Damn if it didn't get hit twice, both by the same guy. This fellow had watched previous calculating competitors drop from their mathematically derived points with impact well short of the target. He dropped when he perceived he was about to pass directly overhead the target. That's the way it looked from the ground also.

Dropping an easily deformable object isn't as simple to calculate as an aerodynamically shaped solid object. The Norden bombsite would work for the latter but not the former. Good luck to all the competitors! Bring your slide rules.

I'll be in town for the weekend. I'll be driving in from Kenai on Friday and picking up my better half at the airport later Friday evening. I normally sleep at the Holiday Inn Express on Spenard Rd.

What time will you get there?

I'm arriving on fri afternoon and out sun eve. Staying at Inlet Tower Hotel. Alaska Air thru Seattle.

Greg-

The show was a hoot. It was nice to meet those of you I did.

See you next year!

Greg-

Who won the husky?

The winner and winning ticket # seems to be the best kept secret in Alaska for at least 24 hours every year...

Sorry to miss it, but I did go ski flying today. Still two feet of snow on the ground and on the runway. It's crazy!

Looks like an older dentist from anchorage. Congrats

bigrenna, did you take any photos at the show? Usually, somebody puts a bunch of photos up to give us all an idea of what we missed. Have not seen any this year yet, here or on SC.org......

Here is a writeup of the show:
http://www.alaskadispatch.com/article/2 ... n-festival

It was a Great Show...
Even with the rain and snow Saturday which kept most folks in the FedEx Hangar.
Mike Hunt, the fellow talked about in the article, owns the hangar I keep my plane in

I learned a lot, and looked at some neat stuff.
Notably,
Alaska BushWheels new products like Skywagon tailwheel/spring components, replacement main wheels/brakes (6"), along with all their other goodies.
ElectroAir High Energy Ignition for the Six Cylinder stuff,
And McCauley building Composite propellers (no wood cores . Nothing like competition to lower prices!

Lots of electronic navigation/ADS-/XM stuff which I just walked by. For now I'll just keep my windscreen clean... It's much less expensive

If you've never been to the show, you should try to get up there. You won't regret it.
