Abstract

The invention discloses an aerodynamic layout structure of a Mars landing patrolling device, and relates to the technical field of aerodynamic layout of patrolling devices, the aerodynamic layout structure comprises a cabin body, the cabin body is of a revolving body structure, and the cabin body comprises a head part, a rear body, a transition body and a tail part which are sequentially arranged from bottom to top; the mass center of the cabin body is arranged on one side of the axis of the revolving body structure; a balancing wing which is telescopically embedded in the rear body, the balancing wing is arranged on the other side of the axis of the revolving body structure, and when the balancing wing extends out, the attack angle of the Mars landing patrolling device can be changed into 0 degree; according to the pneumatic layout structure of the Mars landing patrolling device, the mass center of the cabin body is offset, the patrolling device can enter at an attack angle without unfolding the balancing wings, and the balancing wings extend out before parachute opening, so that the attack angle of the patrolling device returns to 0 degree, parachute opening safety is guaranteed, the service time of the balancing wings is greatly shortened, and the requirements on an actuating mechanism and a heatproof system of the balancing wing are reduced.

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...
