The five-sided parachute with oscillation damping
Safety through innovation: the PENTAGON parachute distinguishes itself through innovative design, combined with high-quality materials. After deployment, the PENTAGON impresses with a rapid opening, immediate oscillation damping and a low sink rate. The result is a rescue system you can fully trust in any situation.
Five sides for high pendular stability. The five-sided shape is self-stabilising: if the PENTAGON experiences a pendular impulse towards a corner, the restoring force will automatically act in the opposite direction. Opposite a corner is an edge, where the airflow is significantly different and this counteracts unwelcome oscillations. The resulting pendular stability is excellent.
Quick to open, slow to descend. The sink rate is extraordinarily low: during certification, with maximum load, the Pentagon 120 had a sink rate of 5.2 m/s.
Five corner vents for fast opening. Five corner vents assist inflation during the opening. The opening is faster and more reliable than with conventional parachutes. This is not only critical when close to the ground, but it also reduces the risk of the parachute getting tangled in the paraglider's lines before opening.
Equal suspension line length for uncomplicated packing. A prerequisite for quick opening is that the parachute is packed regularly. The PENTAGON is quick and easy to pack. The base and centre lines are all the same length and equal distance from each other. They are also colour-coded. This means that the risk of errors during packing is minimal.
- The PENTAGON was designed in collaboration with Urs Haari of High Adventure. Urs drew on his experience of over 300 deployments with various parachutes.
- He extensively tested the PENTAGON during the different design phases. The focus was on tests with the paraglider attached. In practice, this is much more common than the certification test scenario where the paraglider is jettisoned. The practical tests were supplemented by flow simulations of various designs. In the end, the Pentagon was the best of all solutions.
