Line strength

Over the last couple of months we’ve had a number of gliders fail because there lines were no longer strong enough to fly safely. In each case the pilot was disappointed – that’s entirely understandable – but in a couple of cases surprised as well. So what might be [...]

Airflow around a wing


You may have read an article that appeared in Skywings last August about porosity. In that article I referred to the diagram in Ozone’s paper about SharkNose technology which showed how the difference between the internal wing pressure and the external pressure is greatest at the leading edge (Figure 1). [...]

Why do lines shrink?

Since we started using laser equipment to measure glider linesets at Aerofix, we’ve measured over a thousand gliders. Measuring the distance from the risers to every attachment point on a canopy reveals exactly where line lengths deviate from specification, and the program we wrote enables us to determine exactly what [...]
