The patent for China Science Aerospace's launch vehicle has been granted approval, which can improve the noise environment of the rocket’s inverted conical section.

Qichacha APP shows that recently, Beijing Zhongke Yuhang Technology Co., Ltd. was granted a patent for “A Launch Vehicle.”
The patent abstract from Qichacha indicates that this application relates to rocket technology, including: a fairing, an inverted conical section, and a body cylinder segment, with the upper edge of the body cylinder segment fixed to the lower edge of the inverted conical section;
the upper end of the inverted conical section is inserted into the interior of the fairing, and the upper edge of the inverted conical section is fixed to the inner wall of the fairing near its lower edge;
the part of the fairing between the upper edge of the inverted conical section and the lower edge of the fairing is used as a shielding skirt segment to shield pulsating pressure on the inverted conical section.
This application can reduce the pulsating pressure experienced by the inverted conical section, while also ensuring the capacity of the fairing, reducing the structural strength requirements for the inverted conical section, and additionally, this application considers the fairing, inverted conical section, and body cylinder segment, making the pulsating pressure changes more gradual, improving the noise environment inside the rocket’s inverted conical section and instrument bay.
