Inspections and system audit
The use of unmanned aerial vehicles to inspect buildings and structures such as wind turbines and bridges always involves landings when the UAV is operated by battery. Comprehensive inspections require time, which can be gained by using tethered drones. Uninterrupted inspections makes it possible to significantly improve the quality of the audit results.
Infrastructure
Bridges not only connect two places, they are an elementary component of the traffic infrastructure. Both road and rail bridges have to withstand constantly increasing loads and function perfectly. Extensive inspections, however, always represent a restriction in usability. Drones can quickly and cost-effectively replace simple visual inspections under and next to the bridges, as well as on the bridge piers.
Facades
Buildings require occasional inspections. These range from thermographic images and inspections of elaborate ornamentation on historic buildings to comprehensive checks for the smallest building cracks that can occur, for example, due to subsidence of the ground. To enable these flights to be carried out in one piece, it makes sense to use tethering without batteries.
Wind Power Plants
Wind turbines are a fundamental part of the energy transition. For this to succeed, the operation of the plants must be ensured, because only a safe wind turbine can generate electricity in the long term. With imaging measures, a single rotor blade can still be flown with one battery charge. However, if further sensor technology is to be carried along without losing the time advantage compared to climbing the turbine, cable-based flight is the only alternative.
