Purchase of a new racing car, or one that did not have a parachute, will require very specific information. We will need to know the weight, Configuration, and operational speed of the race car. Do not guess. This information must be accurate. Mounting position is very important. This item must be frankly discussed, or you will not have a parachute that will be certain to operate as you wish.
Inspection of the main parachute and pilot chute are also very important. Do not overlook the mounting point, pack placement, and release line. Any malfunction is dangerous. Be sure to inspect the chute after each run for damage, especially the pilot chute. Pilot chutes can collect rocks and other debris. The extra weight can cause problems in opening time.
Storage of the parachute is important for long term safety. It should be taken out of the pack and stored out of sunlight. Nylon can be damaged by sunlight. Many drag racing cars equipped with parachutes that run between 150 and 175 MPH do not use their parachutes on each run. However, if there is a brake failure, or other problem, a parachute will be of great importance, instantlyl Other racing cars, especially Bonneville cars that run only a few times a year, also experience the same problem of a chute which remains in the pack for too long. In any case the chute should be operated, or repacked on a regular basis.
Tie free length into knots as shown (chaining), and detach pilot, to avoid tangling in the washing machine.
Tie the lines together (see picture) so that they will not tangle. Place the parachute in a washing machine and wash in warm or cold water. After washing the chute, untie the lines. Then, hang it out to dry, out of direct sunlight. It can be dried in a drier on the low heat setting.
The pilot chute can also be washed in the machine, however it's best to wash it by hand. Let it hang to dry.
Everything you have done so far will not help you if the parachute is packed incorrectly. At Deist Safety we are the only manufacturer to attach rubber bands to the mounting plate. The use of rubber bands will decrease the deployment time by half. In addition, the free lines will not tangle. Furthermore, the parachute will be less likely to spin. For these reasons the packing method using the rubber bands is shown.
Pictures tell the tale, and there you have it. The parachute is really a very precise part of the race car. It just is often taken for granted until you need it. At that point it had better be right!
