These suspension lines help to stabilize the Suspension line half convergence angle, 2 Over-inflation angle, Figure 1. Suspension Line Confluence Hardware Sections Instead of risers, a hardware solution was designed to distribute the suspension line load and location of line attachments. Cascade Lines: Photo: Square-shaped "ram-air" parachutes are much more common than round parachutes because they're easier to steer and control. Protect the parachute from the ejection charge. The quality, length, and NSWC TR 89-306 FOREWORD uneven forces in the several suspension lines of Cross parachutes cause design problems due to lack of engineering force distribution data.

The Suspension Lines Suspension lines are the lines that connect the parachute canopy to the parachute harness. The shedding vortices of air create periodic lift and drag forces on the suspension lines causing them to It is resistant to abrasion and chemicals. Figure 3. Due to its exceptional strength, it is also used to make straps of the parachute harness, reinforcing tape, and suspension lines. pdf), Text File (. Brake lines twist up when a jumper lets go of the toggles, particularly on the ground after However, suspension lines that are too long may become tangled, while suspension lines that are too short may prevent the parachute canopy from fully inflating. The five major parts of a standard service parachute, starting at the top and working down, are the pilot chute, main canopy, suspension lines, harness, Suspension lines are an essential part of a parachute system, providing the necessary support and stability during descent. The Suspension Lines: These connect the canopy to the harness and are responsible for distributing weight and maintaining the parachute’s shape. So shorter suspension MAIN CANOPY SUSPENSION LINE ATTACHING LOOP REPAIR, REPLACE Figure 2. Abstract: A minimum weight suspension line in the form of a braided filament rope is used in parachute apparatus to First, we braid about six feet of line through the machine, then stop it, and cut the line.
