Skid-type landing gear of an unmanned helicopter

Abstract

The invention discloses a skid-type landing gear of an unmanned helicopter, which belongs to the technical field of unmanned helicopters, and solves the problem of heavy structure, large and complex parts, and limited deformation of the bow beam of the landing gear in the prior art, resulting in its shock absorption and limited ability to absorb impact energy. The landing gear includes two sets of skid tube assemblies and two sets of arch beam assemblies; the skid tube assembly includes a skid tube, the arch beam assembly includes a sleeve and two half arch beams, one end of one half arch beam passes through the sleeve It is slidingly connected with one end of the other half-arch beam, and the other end of the half-arch beam is fixedly connected with the skid tube; along the direction gradually away from the sleeve, the half-arch beam is divided into successively connected horizontal sections, arc sections and inclined sections ; The side of the semi-arched beam facing the fuselage of the unmanned helicopter is hinged with the fuselage of the unmanned helicopter. The landing gear can be used for buffering when the unmanned helicopter lands.

Description

technical field [0001] The invention belongs to the technical field of equipment used for cooperating with or mounted on an aircraft, and in particular relates to a skid-type landing gear of an unmanned helicopter. Background technique [0002] The unmanned helicopter landing gear has the functions of supporting the carrier, transmitting ground loads, shock absorption and absorbing impact energy, reducing overload caused by landing impact, and providing a ground transfer interface. [0003] The existing unmanned helicopter landing gear usually includes the following two types: one of them relies on a buffer for shock absorption and buffering. The landing gear of this structure has a heavy structure, a large number of parts and is complicated due to the buffer, and the use of More maintenance work is required in the process; the other one only relies on the elastic deformation of the thin-walled pipe (mainly the bending deformation of the bow beam as a whole) to absorb energy...
