Flexible base with reinforcement

Abstract

The invention relates to the technical field of flexible pedestals in cold launching devices, and concretely relates to a flexible pedestal with a strengthening layer. The flexible pedestal sequentially comprises the strengthening layer and a protection layer from the internal surface of the body of the flexible pedestal to outside; the strengthening layer is a porous carbon / carbon hard felt composite material layer; the protection layer sequentially comprises an inner protection layer, a shielding layer and an outer protection layer from inside to outside; and each of the inner protection layer and the outer protection layer is an aramid fiber / flame retardation chloroprene rubber composite material layer. The strengthening layer is bonded to the internal surface of the flexible pedestal body, can improves the rigidity of the pedestal, and is made of a carbon / carbon hard felt composite material, and the material has light weight and high rigidity; and the protection layer is adopted outside the strengthening layer to protect the strengthening layer, and the protection layer is made of an aramid fiber / flame retardation chloroprene rubber composite material, and has flame retardation and anti-scour performances.

Description

technical field [0001] The invention relates to a flexible base technology in a cold launching device, in particular to a flexible base with a reinforcing layer. Background technique [0002] The flexible base is the key equipment of the cold launch device. It is installed at the rear of the launch tube and is used to transfer the recoil load under the gas pressure in the launch tube to the ground to reduce the impact on the launch vehicle. In order to adapt to different road surface heights and uneven working conditions, the flexible base leaves a certain gap with the ground after installation, and under the action of internal pressure, it contacts the ground through its own flexible large deformation to effectively transfer the load. Because it generally adopts flexible materials and multi-curved structure design, the rigidity of the bottom surface of the base is poor, especially when the diameter of the base is large, it is easy to contact and wear with the ground during ...

Problems solved by technology

Because it generally adopts flexible materials and multi-curved structure design, the rigidity of the bottom surface of the base is poor, especially when the diameter of the base is large, it is easy to contact and wear with the ground during use, and long-term use will affect its bearing capacity. Sealing performance, but also reduces its road adaptability
