A launch system and method for a launch vehicle that can save initial launch fuel includes a support structure, characterized in that: the support structure consists of a horizontal support frame (3) and an ascending section support frame (4), a horizontal track section (5) is installed on the horizontal support frame (3), an inclined track section (6) connected to the horizontal track section (5) is installed on the ascending section support frame (4), a launch acceleration pipe (10) is fixedly installed on the horizontal support frame (3) and the ascending section support frame (4), an electromagnetic catapult (14) is installed on the electromagnetic catapult slide rail (13), a rocket trolley (8) is installed on the horizontal track section (5) and the arc track section (6), and a rocket bracket (9) is provided on the rocket trolley (8). The present invention has a reasonable structure, can obtain sufficient initial velocity before launch ignition, can save launch fuel, can increase the effective payload, and is conducive to saving launch costs.

The invention relates to the technical field of plate stacking and carrying, in particular to an intelligent continuous plate production and stack transfer robot which comprises a transfer support, and the space below the transfer support is divided into a plate grabbing station, a middle transfer area and a stacking area in the length direction; a transfer hanging bracket is arranged under the transfer support, and a rope driving mechanism matched with the transfer hanging bracket is arranged on the transfer support and used for achieving lifting of the transfer hanging bracket. A composite grasping mechanism is arranged below the transfer hanging bracket, comprises a clamping unit and a vacuum adsorption unit, and is equipped with a buffer height control assembly; a positioning locking mechanism matched with the transfer hanging bracket is further arranged on the transfer support, comprises a transverse driving assembly, a locking base rod and an anti-falling frame and is used for achieving horizontal accurate movement and locking and anti-swing. Through combination of rope-driven lifting and positioning locking, the stability problem in the heavy-load plate transferring process is solved, the adaptability is improved by combining grabbing, efficient, continuous and automatic transferring and stacking of a production line are achieved, the structure is simple, cost is low, and reliability is high.

The utility model belongs to electric fire range technical field discloses a kind of plasma generation assembly and electric fire, wherein, plasma generation assembly includes nozzle, plasma needle and cyclone tank;The nozzle is cylindrical structure, the cyclone tank is connected in the nozzle bottom end and is formed wind cavity with the nozzle inner side wall, one end of the plasma needle passes through the bottom wall of the cyclone tank and is located in the wind cavity;Several spiral grooves are equipped on the outer side wall of the cyclone tank, the spiral groove extends from the bottom wall of the cyclone tank to the upper wall of the cyclone tank, the wind cavity is communicated with outside by the spiral groove.Set up this spiral groove, wind can obtain higher acceleration in the process of flowing through spiral groove, the loss generated in the process that wind enters spiral groove is less, so that the flow and flow rate of wind that can enter the inside of wind cavity are all greater, more easily blow arc.
