Parachute Instruction Manual

Drag racing and Bonneville cars are moving faster and quicker each year. More and more racing efforts are finding that they must add a parachute. Others are building new race cars. Many racing vehicles change hands each year. Often they are in need of a different parachute.

Parachutes are a very carefully engineered part of a racing car. They look similar, but can be very different in application and operation. Some manufacturers provide a limited number of models. They are designed to be rather broad in their stopping ability. They usually work well for the uses intended. At Deist Safety we have many models. This is the result of over fifty years of continuous testing and development.

Each parachute is designed for the specific weight, speed and air flow required. If you are changing classes, or purchasing a new race car, check with us to be sure that you choose the correct chute. Do not guess or estimate. Bad information will give you a parachute that may not operate properly.

Pilot chutes are often taken for granted. Deist Safety provides pilot chutes that are calibrated for a specific chute design. The spring tension, shape, lengthy and weight are precise.These items are formulated for quick and efficient opening of the main canopy. Tow and bridal lines vary in length and number. These items are also calibrated to provide proper opening rate and shock loading to the race car.

Canopies are often very similar in appearance. There are large, but subtle, differences if the parachute is to be designed for a specific race car speed and configuration. The density of cloth, number and size of panels, and other items will vary. Changes in speed (faster or slower) can materially change the operation of the parachute.
