DS'n Canada
 

Anybody in Canada pull off dynamic soaring yet?

What is that Jan???

..some way of extracting more energy from the air than the dynamic energy you start with (ie launching at the top of a hill or sand dune)...I've read about it, but don't understand how it works.......

Andrew go to www.dynamic-soaring.co.uk. I have footage on video of a glider doing 176mph. Search dynamic soaring and u should be able to find some footage or stop by my place when going thru the Bay.

I've found a few DS sites in the B.C. interior which rival a couple of the sites I have flown in California, two of the hills are near Ashcroft which is about 300KM from Vancouver and I found an excellent DS ridge about 10KM outside of Cache Creek. There is also a good hill at Thompson River Estates outside of Savona (near Kamloops).

I also have reliable reports of excellent DS hills in the Princeton and area which is just a few hours from Vancouver.

I have not had a radar gun on my plane during my trips to these hills but extremely high speeds were attained by my Rimmer design (HN1038-2.4metre) at the Ashcroft and Cache Creek sites.

The only problem is that these sites are unflyable in the winter time (at least by me) because of the -35 degree temperatures.

I am going up to do some flying at the end of this month and I will take photos and post them to this board.

I'm sure you don't have to worry about handglider traffic with DS'n! I'm going to order a JW wing from Bowman's Hobbies when I recover from my big Edge...will have to go visit bro in Mission. I am tempted to think a hotliner would be good for learning the zone as the first DS toss must be an anxious one!

DSing in canada
 

About four or five years ago I managed to DS on the middle of Saskatchewan ... and no, I'm not kidding.

At a regular slope site we were having a marginal day. with the wind a little too north for our slope (the edge of the Qu'Appelle Valley) - there is a spine that forms a bowl at a valley corner, leaving a bare face on the downwind side.

DSing does not rely on the normal slope lift, but actually spins the lifting process on its side. kinda.

for those unfamiliar, you basically enter a series of loops, paralell with the back face of a slope, ro a 45 deg angle on the plane of the loops. the loop is about half above the slope, and half below, you pick up energy from the wind as you climb and then dive in the loop, and as you continue diving in the dead air behind the slope, you gain even more speed.

It takes some time to get used to the idea, and rule number one I was taught on the slope was don't fly behind the hill - and this is what this is.

So, I pitched one of the home-built F3B planes we took to Romania off the face, moved across the marginal lift (lots of wind, bad angle) in front and peeled over and dived behind the hill ... first attempt didn't work and I landed on the top of the back slope ... then tried again.

A little more heave in the throw, a bit more aggressive entering the back of the slope and smack, one clean loop, and carrying more speed, boom, another clean loop, and wooosh ... I pointed it skyward and climed out to probably 200' above the slope ... on only two clean rotations ...

The next try I made three clean loops and got the plane going faster than I have ever seen it go, and there was no ballast in it! It seemed to climb for ever when I bailed out of the loops.

Third try ... Elevator folded on the second loop ... and that was that.

People smarter than I figure this is how gliders will get the speed record back from the turbines.

Here is a site with lots of videos of dynamic soaring

Thought I would post a couple of photos' of some DS and slope sites in the B.C. Interior.

Conditions on these hills are excellent right now.
