This invention provides a design method for frequency adjustment of a rocket body wind load model. First, the target value of the first-order frequency of the wind load model is determined based on the first-order frequency of the actual rocket body erected on the launch pad and the similarity principle of the Strouhal number (Sr). The wind load model is then designed based on the target first-order frequency value. A frequency adjustment device is designed to ensure that the adjusted frequency value is between 0.9 and 1.2 times the target value. Modal tests of the wind load model are conducted outside a wind tunnel to verify whether the first-order mode of the model meets the requirements after adjustment. The model is then installed inside the wind tunnel and modal tests are performed. Through frequency adjustment, the first-order frequency of the model is ultimately guaranteed to meet the requirements. This invention solves the problems of frequency deviation between theoretical models and actual products, as well as the deviation of the first-order frequency of products with different fixed support boundaries. It ensures that the first-order bending frequency of the wind load model installed in the wind tunnel for wind testing meets the design requirements. Furthermore, this frequency adjustment device can be used for rocket wind load models of similar diameters and can be repeatedly applied to multiple models.

The rocket launching platform is arranged at one end of the erecting box assembly, and the launching rotary support is rotationally connected to the end of the erecting box assembly provided with the rocket launching platform. The first double-sided tooth groove support arm, the second double-sided tooth groove support arm and the pulling rope system cooperate to erect the rocket, and the launching is completed. The erecting is driven by a brand-new motor, the system composition is relatively simple, the reliability and safety of the erecting and launching system are improved, the erecting and launching process is fast in response and high in precision, the rocket can be erected and launched at any site and terrain, and the future mobile launching demand of the launch vehicle is met. After launching, the device can return to the initial state, the rocket can be hoisted again for the next launching, and the rocket launching efficiency is improved.

This invention discloses a hydraulic control system and control method, belonging to the field of aerospace technology. The hydraulic system includes a hydraulic power unit integrated within a container, comprising a hydraulic oil tank, a motor pump group, a safety valve group, and a flow divider valve group. An erection control unit is connected to an erection cylinder for erection and leveling. A leveling control unit is connected to a launch pad leveling cylinder for lifting and leveling. A tilting control unit is connected to a tilting cylinder. An accumulator is connected to the inlet of the tilting control unit, used to supply oil to drive the tilting support to avoid obstacles after receiving a takeoff command. The return ports of each control unit are connected to the hydraulic oil tank. The control method includes erection, leveling, accumulator pressurization, rapid tilting, and erector frame leveling steps. This invention uses a container-integrated hydraulic power unit to achieve mobile launch without reliance on external support; the flow divider valve group supplies oil independently, ensuring no interference between units; the accumulator instantaneously releases oil to drive the tilting support to quickly avoid obstacles, resulting in fast response, high reliability, and easy rapid deployment and withdrawal.

A launch pad for a weather sounding device, relating to the field of weather detection equipment technology, is used to secure a balloon before its launch. The launch pad includes a T-shaped support, comprising a horizontal crossbar and a vertical bar fixedly connected. The bottom of the vertical bar has a fixed connection portion that is fixedly connected to the ground. The horizontal crossbar extends outward to form a placement portion for placing a weather monitoring device and a support portion for carrying an uninflated balloon. A fixing portion for securing the balloon rope is also formed on the crossbar. The placement portion and the support portion are located on either side of the fixing portion. This application uses a T-shaped support fixed to the ground to support the balloon, with the placement portion and the support portion on the T-shaped support respectively carrying the balloon body and the weather monitoring device. The fixing portion secures the balloon rope, allowing the balloon to be fixed to the T-shaped support before launch. Launch can be achieved by opening the fixing portion, avoiding the dangers associated with hand-held operation.
