What are the civil vertical take-off and landing fixed-wing UAVs.

In recent years, since multi-rotor drones are not affected by the advantages of site restrictions, hovering, and low cost, their models and numbers have increased rapidly. However, due to factors such as power and aerodynamic layout, multi-rotor drones have. It is not easy to meet increasingly stringent user needs in terms of flight time. Fixed-wing UAVs have long endurance and high speed, but they require a take-off runway, which significantly restricts their availability. Since the last century, engineers have continued to explore, seeking an integrated technology that can take off and land vertically and guarantee high speed and long endurance. Due to technological advancements, vertical take-off and landing fixed-wing UAVs have become a reality and have gradually emerged and have moved to civilian use. The editor will take stock of the rookies of civilian drones at home and abroad that have a lot of thoughts.


Chinese drone supplier JOUAV released the CW-20 UAV in 2015. It adopts a composite wing form and is based on a conventional fixed-wing aircraft. It adds a multi-axis power unit and flies in a multi-axis mode under takeoff and landing and low speed. The pulling force generated by multiple propellers overcomes gravity and aerodynamic resistance to pass. In contrast, at high speed, it flies in a fixed-wing mode through the aerodynamic lift to overcome gravity, and the propeller that pulls forward overcomes aerodynamic resistance to achieve flight. The composite wing solution does not require additional mechanisms and has a simple structure; there is no large-scale flight attitude change, and navigation is easy to solve. Therefore, the composite wing vertical takeoff and landing solution is currently the most reliable long-endurance vertical take-off and landing UAV solution with the lowest technical risk. CW-20 series combines the characteristics of fixed-wing UAV with extended flight time, high speed and long-distance, and the function of vertical take-off and landing of rotary-wing UAV. It can be used in complex terrains such as mountains, hills, jungles, ships, and other challenging to use fixed-wing UAVs. In areas with dense buildings, the "JOUAV’s CW-20" can operate without the need for runways and takeoff and landing airspace.



SonGBIRD 500 series

The SonGBIRD 500 series is a composite-wing vertical take-off and landing UAV developed by Revolution, Germany. It also uses a composite-wing vertical take-off and landing solution, which can ensure the vertical take-off and landing of the UAV and enable the UAV to maintain a high flight: speed and long battery life. The SonGBIRD 500 can fly for up to an hour under normal weather conditions, while the on-site installation time only takes less than 10 minutes, making it a very efficient and high-return drone. Depending on the required accuracy, the flight covers an area of 2-15 square kilometers. The advanced automatic flight of SonGBIRD 500 has the "Click&Fly" feature, and one operator can complete the control without professional control skills. SonGBIRD 500 series products can generally operate under various severe environmental conditions. For example, the SonGBIRD 500 can meet the flight usually in harsh extreme environments such as level 8 wind (wind speed up to 20 m/s), high temperature and high humidity, heat, and cold. Its strong environmental adaptability makes it a robust and reliable tool. SonGBIRD 500 has a payload of 500 grams and can be equipped with a camera or customized to provide visible light cameras, multi-spectral cameras, near-infrared and thermal imaging cameras, etc. Because it does not require runways and take-off and landing airspace, SonGBIRD 500 can operate smoothly in areas with complex terrain and dense buildings such as mountains, hills, jungles, etc. This dramatically expands the scope of drone applications and can be applied to precision agriculture and high-precision surveying and mapping. , Professional search and rescue, and many other fields.



Wingtra, Switzerland

The composite UAV developed by Wingtra adopts a composite wing solution, equipped with fixed wings and equipped propellers in front of the wings. It does not have too many requirements for take-off and landing sites. It can take off and land freely, even in narrow areas between houses or dirt roads. The drone will switch to a fixed-wing mode after launching, with a range of up to 60 kilometers and a speed of 100 kilometers per hour. During the flight, operations such as hovering and hovering can also be completed to perform monitoring tasks more accurately. The Wingtra aircraft has a minor appearance and a carrying capacity of 1.5 kg, but it is sufficient to carry a small payload to perform inspection tasks. The first task after its advent is likely to be forest management.



American Martin UAV -- V-Bat

The V-BAT UAV adopts a tailstock vertical take-off and landing form. The ducted fan at the bottom of a broom allows the UAV to take off and land upright. After being lifted into the air, it will be converted into a horizontal flight mode and fly like an ordinary aircraft. The tailstock type control is difficult, especially in the process of horizontal flight hovering. It is difficult to transition smoothly, the reliability is relatively low, but the efficiency is relatively high. According to Martin UAV, the V-Bat can fly continuously for 8 hours at a speed of 50 mph, with a range of up to 300 miles (482 kilometers) with enough fuel and a maximum speed of 100. Miles per hour, the ceiling is 15,000 feet (approximately 4572 meters).
