Problems solved by technology
[0005] In order to solve the above problems, the present invention provides an adaptive walking landing gear and its control method, which solves the problem of insufficient terrain adaptability of the existing vertical takeoff and landing aircraft landing gear. Compared with the existing various types of terrain adaptable landing gear, It has better carrying capacity, and the landing point has a larger choice space. Through the adaptive adjustment control method, it can ensure that the landing gear can adaptively adjust the attitude according to the terrain, and land safely and smoothly on the rough terrain; and it has omnidirectional walking. The ability of the vertical take-off and landing aircraft greatly improves the flexibility of the vertical take-off and landing aircraft on the ground, and expands the range of capabilities of the vertical take-off and landing aircraft to perform tasks

The invention discloses an adaptive walking landing gear and a control method thereof, wherein the self-adapting walking landing gear includes: at least two outriggers with the same structure, the outriggers include a hollow rotating platform, and a rotating shaft is connected to the rotating platform , the rotating shaft is rotatably connected to the rotating connector through a bearing; one end of the rotating connector is flexibly connected to one end of the rocker arm, the other end is connected to one end of the secondary buffer mechanism, and the other end of the secondary buffer mechanism is connected to the The arm body of the rocker arm is rotatably connected; the other end of the rocker arm is movably connected with a primary buffer; the arm body of the rocker arm is rotatably connected with one end of the small action cylinder, and the other end of the small action cylinder is connected with the first stage The buffer is rotationally connected; the self-adaptive walking landing gear adopts a bionic quadruped structure, each leg has three degrees of freedom, so that the landing gear can change the landing point of each leg in the omnidirectional range, ensuring the When descending, the body is in a horizontal posture.
Description
technical field [0001] The invention relates to the technical field of vertical take-off and landing aircraft, in particular to an adaptive walking landing and a control method thereof, which has the functions of adaptive terrain landing and omnidirectional walking. Background technique [0002] Due to its vertical take-off and landing characteristics, the vertical take-off and landing aircraft has stronger adaptability to terrain than fixed-wing aircraft, but because of its fixed structure, it still has insufficient adaptability to various complex terrains. When carrying out tasks such as disaster area rescue, material transportation, and terrain surveys in various terrains such as mountains and rocky beaches, the complex terrain makes it difficult for vertical take-off and landing aircraft to land. Therefore, a higher terrain adaptability is proposed for the landing gear of vertical take-off and landing aircraft. Require. [0003] The current traditional VTOL aircraft lan...
