AI Technical Summary
Technical Problem
The existing slider is not smooth enough during the launch process, which can easily lead to safety problems on the orbit and cause launch failure.
Method used
An aircraft slider consisting of a heat insulation plate and a friction plate was designed. The heat insulation plate has a trapezoidal structure, and the friction plate is made of polytetrafluoroethylene (PTFE) with self-lubricating properties. The slider plug is connected by threads to form a trapezoidal shell structure, which reduces friction and ablates under aerodynamic heat, maintaining a streamlined shape.
Benefits of technology
By reducing friction and aerodynamic drag, the aircraft can glide smoothly, avoid jamming, improve launch success rate, and maintain aerodynamic performance and structural integrity.
