5kg-Class High-Efficiency Material Delivery Parachute Precise Airdrop Stable Descent for Cargo Protection, Suitable for Emergency Rescue & Field Supplies Lightweight and Easy to Deploy

Introduction to Material Delivery Parachute (5kg Class)

I. Core Parameters (Refer to Common Specifications)

• Applicable Material Weight: Mainly for materials around 5kg (usually allowing a certain error range, such as 4-6kg), suitable for small packages, emergency medicines, communication equipment, food, etc.
• Canopy Size: The diameter of the canopy is usually 1.5-2.5 meters (depending on design standards). The material is mostly lightweight and high-strength nylon fabric, balancing durability and air resistance efficiency.
• Airdrop Height Adaptability: Adaptable to low-to-medium airdrop heights (e.g., 30-200 meters). Some models can be adjusted according to needs to meet the delivery requirements in different scenarios.
• Falling Speed: Through the design of canopy resistance, the landing speed of materials can be controlled at 3-8 m/s (depending on the parachute type and delivery height), which is much lower than the free-fall speed without a parachute, effectively protecting the integrity of materials.
• Weight and Portability: The parachute itself usually weighs 0.5-1.5kg. When folded, it is compact in size (e.g., a storage bag with a diameter of 20-30cm), making it easy to carry and quickly deploy.

II. Structure and Working Principle

1. Canopy System: Composed of the canopy, suspension lines, and parachute fabric. The canopy is designed in a circular or square shape, forming a stable aerodynamic profile after deployment. It generates upward resistance through air pressure; the suspension lines connect the canopy and the materials, evenly distributing the tension to ensure the stable opening of the canopy.
2. Release and Deployment Mechanism: During delivery, the materials and the parachute are fixed by connecting devices (such as buckles, ropes). After detaching from the carrier (e.g., UAV, helicopter, manual throwing), the canopy automatically deploys under the action of air flow (some models require manual triggering of the parachute opener), quickly forming resistance to slow down the fall.
3. Buffer Design: Some high-end models add buffer devices (such as elastic ropes, foam pads) at the connection between the materials and the canopy to further absorb the impact force at the moment of landing, protecting fragile items (such as electronic equipment, glass containers).

III. Application Scenarios

• Emergency Rescue: In disasters such as earthquakes and floods, small materials such as food, medicines, and first-aid kits are delivered to trapped areas by UAVs or helicopters, solving the supply problem when ground transportation is interrupted.
• Field Operations: Providing remote supplies for mountaineering teams, geological exploration teams, scientific expeditions, etc., enabling material delivery without personnel reaching the site.
• Military Use: Used for the rapid delivery of individual combat materials and small reconnaissance equipment, reducing the risk of personnel exposure.
• Civil Logistics Experiments: As an auxiliary tool for UAV airdrops in logistics distribution in remote areas, exploring low-cost and efficient end-delivery solutions.

IV. Advantages and Precautions

• Advantages:
  • Lightweight design, compatible with various delivery carriers (including small UAVs), with high flexibility;
  • Low cost, simple maintenance, suitable for large-scale or high-frequency use;
  • Low requirements for the delivery environment, and can be used near complex terrains (such as mountains, jungles).
• Precautions:
  • It is necessary to select a matching parachute type according to the weight of the materials and the delivery height to avoid excessive speed caused by overloading or too small a canopy;
  • Before delivery, check whether the canopy is damaged and whether the suspension lines are firm to ensure normal parachute opening;
  • It is greatly affected by wind force. In strong wind conditions, the landing point may deviate, so it is necessary to plan the delivery area in advance and evaluate the meteorological conditions.
