Introduction to opening speed and minimum opening altitude (distance) of parachutes!

When explaining parachutes, most people's concerns are, "How fast does it open?" and "What is the required altitude (distance) from the ground?" Since it is something that is useful when falling, there is an expectation or desire for it to open as quickly as possible, even 0.1 seconds faster or 1mm shorter in fall height. However, the top priority for manufacturers is not to shorten the opening time. Rather, they prioritize preventing the intentional delay of opening too early to avoid tearing or structural damage at the seams and surrounding materials, as well as preventing kinks and tangles in the multiple suspensions to ensure a proper opening shape. The opening time of a parachute is proportional to the length from the top (tip) to the connect (connection point). *For more detailed information, please refer to the PDF materials. Feel free to contact us for more details.

Our company provides seminars that leverage our expertise in the development, production, and handling of sky sports flight equipment such as hang gliders and parachutes, tailored to drone crisis management and flight knowledge. https://sites.google.com/view/profeel-shin-kake/ The drone transportation methods envisioned by hang glider operators are completely different from those conceived by current drone-related businesses. The air transport-specific container developed by Adair, when used in combination with multi-rotor aircraft, increases flight speed during the transition from vertical takeoff and landing to horizontal flight, improves energy efficiency, and also allows for an increase in payload capacity by utilizing specialized flight knowledge (patent applied for in February 2025; prototype development currently underway as of March). https://sites.google.com/view/flying-container-for-dorone/ We offer emergency parachutes for drones, including the "OWL-VG," an emergency parachute for unmanned aerial vehicles available in 8 sizes ranging from 2.5 kg to 40 kg based on total aircraft weight, and the "SOL Squad Light," which offers 5 sizes for weights from 55 kg to 220 kg. We can also accommodate requests for sizes other than those specified above, or for specific materials, structures, and opening process arrangements. Please feel free to contact us if you have any inquiries.
