Summary

• Canopy and Fabrico Visual - There were many small and minor nicks in the wing (all patched with rip-stop tape) and pictures detail this below.o Porosity - The porosity was in near new condition for the entire wingo Fabric Strength - This is a pass or fail test, the wing passed.

• Lineso Visual and Physical - 4 lines had sheathing cuts and were replaced. o Length Check - Shrinkage throughout all lines is common, but the trim of the wing was not that much difference.o Breaking Check - 3 lines were broken and all 3 broke above the listed line strength value.

• Risers - No damage found

o Porosity - The canopy was measured for porosity values in 8 different areas of the top and bottom surface. The measurements were made approximately 20 -30 cm inboard from the leading edge in the approximate positions indicated in the diagram below using a porosity meter.

Using the industry standard formula, see below, the wing was found to be in near new condition.

o Cloth Strength - This is a test for measurement of the tearing resistance of the cloth by puncturing the cloth in the middle of a panel of the top surface and increase the load until 600g is achieved. If the material tears more than 5mm before this value is reached then the cloth is deemed too weak and the glider is un-airworthy. The same test is repeated on a panel of the undersurface.

In the Mojo 3 XL the cloth did't tear in the 2 surfaces tested. Both needle holes were patched on the inside.

o Visual and Physical - A visual check of all line set, for any signs of external damage as tears, missing stitches, weak inner core , and also the brake handle knots and the brake lines for any excessive wearing, were performed. I found 3 lines with tears in their coating as seen below.

Useful information

Paraglider Porosity Check

Paraglider porosity is the measurement of the amount of time it takes for a certain volume of air to pass through the paraglider canopy fabric. To test the porosity of a glider, we use the JDC MK 1 Porosimeter, which is the most used porosity meter in the paragliding industry. The MK 1 measures the time necessary for 0.25 liters of air under 4hPa pressure to go through 38.5 cm2 of cloth.

So how does porosity affect your glider?

New gliders are tested by various agencies/organizations to determine their performance and safety (See Paragliding Rating System ) . When these agencies test gliders, the gliders are new from the factory and have very little porosity. Because the structure of paragliders is formed by pressurization, the porosity of a glider also relates to its pressurization. The behavior of a glider will change as the porosity increases. This change in behavior might be, among other things, glide ratio, speed, resistance to collapses, recovery from collapses, handling in turns, and surging. In addition to the performance being affected, the durability is affected as well. If a glider is more porous, it means the material has degraded and it is weaker than it was when you first bought it. If the material is weaker, it can tear easier. These tears might occur when you are launching or landing near rocks or sticks. However, if the material of your glider is significantly weaker, it may even tear during an event while flying, such as a large frontal collapse. Tearing of a glider from a collapse is very unlikely, but it has happened before.

How do you take care of your glider to slow down the again process?

The most popular source of the aging of a glider is UV exposure. You should always keep your glider out of UV when possible. If you are on launch or in the LZ and your glider is unpacked, cover it up with something to prevent UV exposure. If you fly in places where UV is strong, such as Australia, or towards the equator, your glider will age faster than it would in places where there is less sunshine, or less UV.

Is water bad for my glider?

Water is bad for your glider if it is stored in a damp state. The continued exposure to moisture will weaken the canopy, and the lines. If you get your glider wet, its important to let it dry out as quickly as possible. No need to frantically dry it out, but don't let your glider sit overnight, packed up without letting it dry out first. However, we recommend letting the glider air out at room temperature, out if direct sunlight. Exposing a wet glider to direct sunlight can affect the materials (such as lines and stitching). Lines can shrink and weaken when wet and exposed to direct sunlight. If your glider has somehow ended up in saltwater, we recommend hosing it off with some fresh water to get the salt particles off the glider and let it dry in the shade, or inside.

What about abrasion?

Abrasive materials, such as sand and dirt can degrade the protective coating on the canopy. A common protective coating is a layer of silicone on the inside of the canopy material. So, if you fly in places where you're ending up with sand in your glider, you should do your best to remove these materials from your canopy so they don't continue to wear on your canopy. We've seen some grasshoppers in places that actually take bites out of the canopy material to get themselves out.

Where should I avoid storing my glider?

To increase the lifespan of your glider, store it in a dry cool place. Keeping a glider in the trunk of your car in the heat can weaken the protective coating, or affect the lines.
