Skydiving, often considered the ultimate thrill‑seeking adventure, involves much more than simply jumping out of an airplane. To ensure safety, precision, and an exhilarating experience, choosing the right parachute system---specifically the canopy and harness---is crucial. This article will provide an in‑depth guide on parachute systems, explaining the key factors to consider when selecting the right canopy and harness for your needs, whether you're a beginner, an intermediate skydiver, or an experienced professional.
The Basics of Parachute Systems
A parachute system consists of several essential components, the most important being the canopy (the main parachute) and the harness/container system. Together, these elements make up the system that keeps you safe while you experience freefall and descent. Understanding how each part functions and how they work together is essential for choosing the right system for your specific needs.
Key Components of a Parachute System
- Canopy : The parachute itself, typically made of durable fabric, is the most critical part of the system. The canopy slows the descent of the skydiver and allows for controlled landing. It comes in various shapes and sizes, each designed for specific purposes.
- Harness : The harness is the part that attaches the skydiver to the parachute system. It provides comfort, stability, and control during the jump. It is designed to distribute the forces of opening shock and landing across the body.
- Container : The container is the backpack‑like structure that holds the parachute. It contains the main canopy, reserve canopy, and an automatic activation device (AAD), which deploys the reserve parachute if the main canopy fails to open.
Now, let's focus on the two key parts of a parachute system: the canopy and harness.
Choosing the Right Canopy
The canopy is arguably the most important component of the parachute system, as it directly influences how the skydiver experiences freefall and descent. The correct canopy can make the difference between a smooth, controlled landing and an unsafe one.
Types of Canopies
-
Ram‑Air Canopies (Square Parachutes)
These are the most common canopies used in modern skydiving. They are rectangular and designed to create lift, similar to an airplane wing, allowing for a more controlled descent. They are highly maneuverable and provide better accuracy for landing.
Advantages : Greater control during descent, easier landing, more stable in turbulent air.
Considerations : Requires more training and skill to control, especially for landing.
-
These are the traditional parachutes with a circular shape. While still used in some military applications or for specific purposes (like cargo drops), they are largely outdated for recreational skydiving.
Advantages : Simplicity in design, reliable for basic jumps.
Considerations : Less maneuverable, less control over landing, and slower descent compared to modern square canopies.
-
These are a specialized type of ram‑air canopy with internal cross‑bracing that adds to the structure's strength and allows for even higher performance. They are used by expert skydivers, including those participating in canopy piloting competitions.
Advantages : Higher performance, faster, and more responsive.
Considerations : Designed for experienced skydivers; more difficult to handle, requiring skill and proper training.
Size and Load Factors
The size of the canopy is crucial for the skydiver's safety and performance. It depends on several factors, including the skydiver's weight, experience level, and intended use (for example, sport jumping, accuracy landing, or speed).
- Weight : A skydiver's weight determines the size of the canopy. Heavier individuals require a larger canopy for a slower, more controlled descent. Lighter individuals can typically use smaller canopies, which offer faster speeds and more maneuverability.
- Experience Level : Beginners typically use larger canopies (approximately 230--300 sq ft), which provide more stability and easier control. Intermediate and advanced skydivers may use smaller canopies (170--210 sq ft) for higher performance, allowing for more precise maneuvers and landings.
- Intended Use : If you plan to perform precision landings or compete, you'll want a canopy specifically designed for those activities. Cross‑braced canopies, for example, are ideal for speed and performance but may not be suitable for beginners.
Flight Characteristics
- Glide Ratio : How far the canopy can travel horizontally for every foot it descends vertically. A higher glide ratio is crucial when jumping over water or mountainous terrain.
- Responsiveness : The speed and precision with which a canopy reacts to control inputs. More responsive canopies enable intricate movements, while slower, more stable canopies are easier for novices.
Choosing the Right Harness and Container System
The harness and container system forms the backbone of the parachute setup. The harness connects the skydiver to the parachute, ensuring they remain securely attached throughout the jump, and the container holds both the main and reserve canopies.
Harness Types
-
The standard harness features a basic design and is the most common for beginner and intermediate skydivers. Adjustable straps allow a custom fit, ensuring both comfort and security.
-
Designed for speed and performance, racing harnesses are lightweight with minimal padding. They are often used by experienced skydivers who compete or seek the fastest possible freefall.
-
Jumpsuits with Integrated Harnesses
Advanced skydivers sometimes wear jumpsuits that integrate the harness into the suit itself. This design minimizes air resistance and is popular among wingsuit pilots and specialized jumpers.
Harness Fit and Comfort
A well‑fitted harness is critical for comfort and safety during the jump. When trying on a harness, consider the following:
- Adjustability : Look for easy adjustments on leg straps and chest strap for a custom fit.
- Padding : More padding helps distribute the force of opening shock---useful for beginners. Advanced skydivers may prefer less padding for greater mobility.
- Leg & Chest Straps : Leg straps should be snug without cutting circulation; the chest strap should be comfortable yet secure.
Container System Design
The container holds the parachutes and must fit the canopies securely while allowing smooth deployment.
- Main and Reserve Compartments : Separate compartments keep the main and reserve canopies organized and accessible.
- Automatic Activation Device (AAD) : An optional but recommended safety feature that automatically deploys the reserve parachute if the main canopy isn't deployed by a preset altitude.
Choosing the Right Container Size
The container's size must match the canopy size. A container that's too small may cause deployment issues; one that's too large can be bulky and uncomfortable.
Final Considerations
- Training : Regardless of the canopy or harness you choose, proper training is essential. The best gear won't keep you safe without the knowledge and experience to use it correctly. Always train under certified instructors.
- Regular Maintenance : Skydiving equipment must be inspected and packed regularly by a certified rigger. Check the harness, container, and AAD before each jump.
- Personal Preference : Ultimately, the best parachute system fits your personal needs and preferences. Consider comfort, the type of jumping you plan to do, and your skill level.
Conclusion
Choosing the right parachute system is a vital part of becoming a safe and skilled skydiver. The right combination of canopy and harness can greatly enhance your experience, whether you're enjoying a leisurely jump or performing advanced maneuvers. By considering factors such as the type of canopy, your weight, experience level, and intended use, you can make an informed decision that aligns with your skydiving goals. Always prioritize safety, comfort, and proper training to ensure that every jump is as thrilling and secure as possible.
