Abstract

The invention discloses a special-shaped storage tank outflow device, and belongs to the technical field of liquid rocket pressurization conveying systems. A vortex eliminating plate and a partition plate are installed on a flow outlet of a common-bottom storage tank, holes are formed in the vortex eliminating plate, the structural load of the vortex eliminating plate is reduced, meanwhile, the structural weight of the vortex eliminating plate is reduced, meanwhile, the bearing capacity of the vortex eliminating plate is improved through reasonable layout of the holes, and the vortex eliminating plate is of a 120-degree V-shaped structure, so that fluid transition is smooth as much as possible; and meanwhile, liquid tends to be filled to the center, a cover plate is installed on the upperportion of the flow outlet (the axial direction of the storage tank) of the common-bottom storage tank, the liquid tends to flow downwards (accelerate), tangential force for forming vortexes is destroyed, the vortexes and collapse are restrained through the arrangement, and therefore the unusable amount of the liquid in the storage tank is reduced.

Description

technical field [0001] The invention relates to an outflow device of a special-shaped storage tank, which belongs to the technical field of liquid rocket booster conveying systems. Background technique [0002] The common-bottom storage tank has the advantages of shortening the height of the rocket body structure, reducing the length-to-diameter ratio of the launch vehicle, effectively reducing the weight of the rocket itself, and improving structural efficiency. For tanks with a common bottom structure, the propellant outlet of the upper tank is generally set at the lower end of the tank barrel, and the outflow form is side outflow. At the end of the side outflow, due to the influence of the outlet profile, the geometric parameters of the tank, the flow velocity, and the overload and sloshing in flight on the local flow characteristics, the phenomenon of liquid surface collapse and vortex will appear above the outlet. The generation of vortex or liquid surface collapse wil...
