Understanding your glider
Ok. So I am starting my second post with my understand of the glider. Please note that I am creating this blog so that I remember things.:)
Here I go...
First step to learn is (in my opinion) understand your glider. How it is made, how it works, what are the parts of it, etc.
As shown in the picture our wing has a canopy, some lines and controls. Canopy is the topmost part of the wing which keeps us afloat with its aerodynamic behavior. Lines are the strings attached from various parts of the canopy to your harness. controls (or brakes) is by which you control your canopy in the air. When canopy is inflated it takes an airfoil shape (like the shape of the plane's wing) and hence create pressure to pick you up in the sky.
Air is filled in the canopy from the openings at the front end (at the time of inflation). The canopy is closed from the rear end so wind cannot escape from there and so the canopy takes quite strong (rigid) shape.
When you apply little bit brakes (by control lines) the rear part of the canopy is pushed down and hence changing the shape and creating more push upwards. So to get more lift upwards you need to keep little bit pressure on your brakes.
But remember not to push much pressure as it may stall the glider. Mean bring the glider down immediately.
The lines from canopy to your harness are divided in some groups (known as A-risers, B-risers, C-risers, D-risers). the front most lines are called A-risers.
Some glider has their A-risers splitted into two parts. The next set of risers are called B risers.
The last set is the the control lines or brakes.These are connected at the rear most point at the canopy.
Then there may or may not be C and D risers.
