    摘要： A landing gear for an aircraft comprises: a shock absorber strut (1) with upper and lower telescoping portions (2, 3), the upper portion (2) being connectable to the airframe of the aircraft; an arm (4) to extend fore and aft relative to the aircraft and carrying a landing wheel, (7, 7
    1 ), and pivotally connected by a main pivot (5) to the lower portion (3) of the shock absorber strut; and a load reacting unit (9) connected between the arm (4) and the shock absorber strut (1) for reacting to load applied between the arm and shock absorber strut on landing, and an indicator (60) for monitoring the load applied to the load reacting unit (9) on landing. The load reacting unit (9) may be connected between a forward end of the arm (4) and the upper portion (2) of the shock absorber strut to make the gear act as a semi-levered landing gear. Alternatively, the load reacting unit (9) may be connected between the arm (4) and the lower portion (3) of the shock absorber strut to act as a pitch trimmer. The arm (4) may comprise a bogie beam with fore and aft landing wheels (7, 7
    1 ) with the main pivot (5) therebetween. The load reacting unit (9) preferably comprises a fluid pressure unit and the indicator (60) comprises a mechanical indicator that operates at a predetermined pressure threshold.

    摘要： A semi-levered landing gear for an aircraft comprising: a main shock absorber strut (1) with upper and lower telescoping portions, with the upper portion (2) connectable to the airframe; a bogie beam (4) to extend fore and aft of the aircraft fuselage with at least one forward axle and one aft axle for respective forward and aft wheels and a main pivot between the forward and aft axle pivotally connected to the lower portion of the main shock absorber strut; and an auxiliary mechanism comprising a lever unit (92), a spring unit (94) and a positioning unit (90), with a first one of said units pivotally connected to the upper portion of the main shock absorber strut so as to pivot between a predetermined lower position for take-off and landing and an upper position, a second one of said units pivotally connected at an upper end to the upper portion of the main shock absorber strut and pivotally connected at a lower end to the first one of said units, and a third one of said units pivotally connected at a lower end to the bogie beam at an auxiliary pivot and connected at an upper end to the lever, the positioning unit assuming one of a contracted state or extended state for taxiing, take-off and landing, and the other of the contracted or extended state for stowing the landing gear after take-off, and the spring unit providing spring resistance to pivotal movements of the bogie beam about the main pivot during taxiing.
