ドローンによる連続的漏洩水素センシングに対するロータ気流の影響

抄録

Hydrogen is widely used in fuel cell vehicles and spacecrafts, and is deemed as the next-generation energy carrier. On the other hand, hydrogen leakage is anticipated in various occasions ranging from production to consumption. Because system degradation and human error are inevitable and also hydrogen can be easily ignited even by weak magnitude of static electricity, quick, flexible and reliable sensing techniques of leaked hydrogen are required. Previously, we proposed a new wireless high-speed continuous sensing system with a semiconductor-type hydrogen sensor installed on a quadrotor drone [1]. In this study, the effects of the attitude angle and blade rotation on hydrogen sensing are investigated from the view point of the rotor wakes. As a result, we obtained encouraging results regarding the present approach for measuring leaked hydrogen.
