摘要： A vessel includes a vessel body, an engine, a propulsion device, a drive shaft, a partition wall, a bearing, an elastic member, an outer housing, and a positioning member. The drive shaft transmits a driving force of the engine to the propulsion device, and the propulsion device generates a thrust by the driving force. The drive shaft is inserted into an insertion hole of the partition wall. The bearing rotatably supports the drive shaft. The elastic member supports the bearing. The outer housing supports the elastic member, and is fixed to the partition wall. The positioning member positions the elastic member with respect to the bearing and the outer housing by pressing the elastic member.

摘要： A rotary device (e.g., a rotary jet), power generation system, and methods of manufacturing and using the same are disclosed. The rotary jet includes a central axle or shaft, an inlet configured to receive at least one fluid, and a plurality of radial arms in fluid communication with the inlet, configured to rotate around the central axle or shaft. Each radial arm has a nozzle at a distal end thereof and an arc between the inlet and the nozzle. The radial arms extend radially from the central axle or shaft at least in part, and are configured to rotate when the fluid enters the inlet and passes through the radial arms, or when a rotational force is applied to the central axle or shaft. Each nozzle may have an opening facing away from a direction of rotation of the radial arms or facing in a direction parallel with the central axle or shaft.
