The utility model discloses a slab staggering beam column joint reinforcing structure, which relates to the technical field of constructional engineering transformation and comprises a column body, a first slab staggering beam and a second slab staggering beam, the height position of the first slab staggering beam is lower than that of the second slab staggering beam, and a first thickening layer and a second thickening layer are fixedly arranged on the lower end face of the first slab staggering beam and the lower end face of the second slab staggering beam respectively. Stirrup frames are installed on the outer sides of the column body, the first slab staggering beam, the second slab staggering beam, the first thickening layer and the second thickening layer, a filling layer is arranged on the inner side of each stirrup frame, and the bottom face, on the outer side of the first slab staggering beam, of each stirrup frame is lower than the bottom face, on the outer side of the second slab staggering beam, of each stirrup frame; the stress state of the staggered beams is changed by increasing the section thickness of the staggered beams and reinforcing the stirrups, so that the staggered beams of the underground garage are changed from staggered layers to continuous, the stress state of column tops is changed from eccentric stress to axial stress, and the unbalanced bending moment of short columns caused by staggered layers is eliminated.

The application discloses a kind of single-blade card paddle working condition under wheel hub system limit load control method and system, this method is when wind turbine generator set normal operation detects whether blade is in card paddle state, when detecting card paddle failure, shutdown action is carried out, wind turbine generator set first enters load dynamic balance control mode, then calculates the current yaw error in shutdown process, yaw control is carried out to wind turbine generator set based on yaw error, so that wind turbine generator set is far away from directly facing wind direction, reduce the wind load of wind turbine generator set, and then reduce generator speed, when the load of wheel hub system of wind turbine generator set is less than preset threshold, wind turbine generator set carries out unified variable pitch rate feathering control, so that the load of wheel hub system meets design requirement, improve the safety of unit, and then reduce the design cost of wheel hub system.

This invention discloses a modular lift supply aircraft, a combined aircraft, and a method for operating the combined aircraft, relating to the field of aircraft technology. The modular lift supply aircraft is equipped with a lift-providing device, a male docking head, and a female docking head. The combined aircraft includes a main aircraft and a modular lift supply aircraft mounted on the main aircraft. This invention provides a modular lift supply aircraft, a combined aircraft, and a method for operating the combined aircraft, enabling fixed-wing aircraft to achieve vertical takeoff and landing capabilities while still maintaining large payload, long range, and good stealth performance.
