Description

technical field [0001] The invention relates to a static test device and a test method for a power component of a high-altitude all-electric unmanned aerial vehicle, and belongs to the technical field of performance test of small unmanned aerial vehicles. Background technique [0002] High-altitude UAV is an unmanned aerial vehicle whose flight action is controlled by an onboard program. It originated as a special combat aircraft for tactical reconnaissance on the military battlefield. With the continuous deepening of military-civilian integration, high-altitude drones are gradually being used in civil aerial photography, meteorological detection, address survey and other fields. Civilian high-altitude UAVs are different from battlefield combat special aircraft, mainly emphasizing functionality and flight stability. Considering that electric power is easy to obtain, transform and transfer, most civilian high-altitude UAVs use electric power as their energy source. The fligh...

AI Technical Summary

Problems solved by technology

The application of standard power components also has potential technical blind spots. From the perspective of their own technology blockade and intellectual property protection, the manufacturers of functional components only provide relevant operating conditions, operating specifications and safety information in the supporting technical documents of the products. Does not involve detailed performance parameter data

On the other hand, most of the performance information comes only from relatively limited airspace and flight time

[0004] The performance test data for the power components of such aircraft is very scarce. No relevant engineering test methods for high-altitude all-electric UAV power components have been found in the existing technology. The development of high-altitude, high-stability UAV product-related design optimization work provides data support, and the performance and reliability of the corresponding all-electric UAV power components cannot be guaranteed, let alone measurement guarantees throughout the life cycle.
