Semi-rigid mechanical landing gear deployed into the deceleration

The present invention discloses a landing gear reducer expand into the machine a semi-rigid, and the return part of the spacecraft enters the art. Includes a main body, a control loop, the rigidity of the nose cone, the heat shield semi-rigid, semi-rigid heat shield control means and a flexible heat shield means, the control ring body is fixedly connected to the drive means controlling the connection between the rigid ring and the cone, the drive means for controlling the control ring and the rigid cone relative movement; semi-rigid heat shield cover mounted on the semi-rigid heat shield control means, a semi-rigid heat shield control means, respectively the body and the rigid cone is hinged, the control semi-rigid anti heat shield to expand or collapse; semi-rigid outer edge of the heat shield is provided with a flexible heat shield mechanism outward quadratic expansion. The total area of ​​the present invention is greater than one expansion area to expand while maintaining a smaller volume emission retracted state, than to improve the storage device, to improve the aerodynamic surface reducer effect, reducing the complexity of the system, to achieve the double reduction and landing the organic unity of the buffer.
