Abstract

The invention discloses an aerodynamic layout structure of a Mars landing patrol device, relates to the technical field of aerodynamic layout of the patrol device, and comprises: a cabin body, which is a revolving body structure, and the cabin body includes a head and a rear body arranged sequentially from bottom to top , transition body and tail; the center of mass of the cabin is set on one side of the axis of the rotary structure; the trim wing is telescopically embedded in the rear body, and the trim wing is set on the other side of the axis of the rotary structure. When it is out, the angle of attack of the Mars landing rover can be changed to 0°; the aerodynamic layout structure of the Mars landing rover offsets the center of mass of the cabin, and the rover can enter at an angle of attack without deploying the trim wings. Extend the trim wing in front of the parachute, so that the angle of attack of the patrol device returns to 0°, ensuring the safety of the parachute, which greatly shortens the use time of the trim wing and reduces the requirements for the action mechanism and heat protection system of the trim wing.

Description

technical field [0001] The invention belongs to the technical field of aerodynamic layout of a patrol device, and more particularly relates to an aerodynamic layout structure of a Mars landing patrol device. Background technique [0002] At present, only the Mars Science Laboratory Improvement (MSL-I) in the United States has proposed the aerodynamic layout scheme of the Mars entry vehicle with trim wings in the world, which adopts the scheme with no offset of the center of mass. Such as figure 1 and figure 2 Shown are the schematic diagrams of the retracted and unfolded state of the trim wing of the existing Mars-entry vehicle, respectively. When Mars is in the atmosphere, the trim wing 102 is unfolded, and the axial asymmetry of the shape will cause Mars to enter the aircraft 101 to generate lift, and realize that there is an angle of attack to enter; The angle returns to near zero to ensure the safety of opening the parachute. [0003] For this solution with no offse...
