Description

Technical Field

[0001] This utility model relates to the field of aircraft technology, specifically to a frame structure for a two-person wheeled powered paraglider. Background Technology

[0002] Traditional powered paragliders are often used as passenger transport for entertainment and tourism due to their small size and maneuverability. However, these devices have significant limitations: firstly, they can only carry a limited number of people, making it difficult to meet the needs of multiple passengers; secondly, when attempting to design for multiple passengers, flight stability and safety become prominent technical challenges, as the three-point support wheel structure on the bottom is difficult to handle balance control when multiple passengers are on board, which can easily lead to flight instability and safety hazards.

[0003] Chinese patent CN2642547Y discloses a multi-seat air-to-land amphibious aircraft. While it can meet the needs of multiple passengers, the parachute adopts a double-sided, symmetrical, cross-pull structure. The cross-pull nodes balance the force, resulting in good flight stability and easy balance adjustment, which can better address the balance problem when carrying multiple people. However, because it needs to accommodate multiple seats and air-to-land use, the overall structure is more complex, which may increase the difficulty of manufacturing and maintenance. At the same time, it does not explicitly mention the use of high-strength lightweight materials, which is insufficient in balancing lightweighting and structural strength.

[0004] Based on this situation, a frame structure for a two-person wheeled powered paraglider is provided, including a base, wheel frame, seat, protective frame, motor / aircraft engine bracket, parachute connecting frame, and propeller protective frame. Each component is made of lightweight, high-strength materials such as aviation aluminum and carbon fiber-filled stainless steel, effectively reducing weight while ensuring structural strength, thus better meeting the weight reduction requirements of lightweight aircraft. Each component is manufactured independently and is easy to assemble, achieving stable connections through modular design, resulting in low production and maintenance costs and facilitating future component replacement. It can meet the load-bearing requirements for two passengers, and the seat is equipped with an adjustable rail to accommodate different body types. It offers strong handling stability, improving structural stability and safety during flight and meeting the flight performance requirements of a two-person wheeled powered paraglider.

However, the need to accommodate multiple seats and dual-use (air and land) capabilities increases overall structural complexity, potentially raising manufacturing and maintenance difficulties. Furthermore, the lack of explicit mention of using high-strength, lightweight materials presents a challenge in balancing weight reduction and structural strength. The proposed solution features a frame with a rollover protection frame, forming a ball cage structure that provides superior occupant safety and enhances overall security.
