Problems solved by technology

The existing unmanned aerial vehicles fly at a slow speed. In order to increase the flight speed of the unmanned aerial vehicle, the existing technology cannot modify the unmanned aerial vehicle. This is because the modification of the unmanned aerial vehicle needs to include: replacing the power system and increasing the output power of the engine ; Change the aerodynamic layout design of the UAV to reduce the resistance of the UAV; replace the parts of the UAV with lightweight material parts to reduce the quality of the UAV, etc., or the comprehensive use of the above modification methods
Since the UAV itself is a very complex system, its aerodynamics and propulsion, structure and materials, dynamics and control must be fully considered in the overall design, and the existing technology cannot be reasonably modified
This is due to the traditional technology, the way to modify the UAV is often more complicated, and even involves the modification of the flight control system. The existing technology cannot provide vector thrust for the UAV, and cannot control the engine on the platform. Thrust magnitude and direction
