Problems solved by technology
[0002] When verifying the static strength of the whole aircraft ground, most of the test items are carried out under the state of the whole aircraft suspended in the air. Usually, the aircraft front landing gear and the left and right main landing gear are statically restrained. At present, the crowbar type is generally used, that is, one end of the crowbar is connected. The other end of the dummy wheel of the landing gear is connected with the position control actuator and the stop protection pull plate; the production cycle of this type of fixture is long, and the overall size of the crowbar support is relatively large, which occupies more space and is easy to interfere with the loading point

The invention discloses a full-aircraft statically determinate support device and method. The device comprises a restraining system of a plurality of two-force-rod assemblies, and the restraining system conducts hinge supporting restraining on an aircraft landing gear, specifically, the hinge supporting restraining is conducted on the vertical direction of a front landing gear, the vertical direction / heading direction / lateral direction of a left main landing gear and the vertical direction / heading direction of a right main landing gear; a two-force-rod assembly with the two ends hinged and supported is used at each constraint position, and the length of the two-force-rod assembly can be properly adjusted to calibrate the installation posture of the aircraft. One end of the two-force-rod assembly is hinged to a corresponding joint of the undercarriage, and the other end of the two-force-rod assembly is hinged to a vertical / lateral / heading corresponding fixed joint. The two-force-rod assembly is used for conducting hinge support statically determinate constraint on the aircraft, force transmission is direct, the structural form is simple, the occupied space is small, the total constraint point error is small, the constraint point error is only hundreds of N under the pure airtight working condition, and the constraint point error is about one thousand N under other conditions.
Description
technical field [0001] The invention relates to the field of aircraft structural strength testing, in particular to a statically determinate supporting device and method for the whole aircraft, which are suitable for supporting the whole aircraft in the air for ground strength verification of the aircraft. Background technique [0002] When verifying the static strength of the whole aircraft ground, most of the test items are carried out under the state of the whole aircraft suspended in the air. Usually, the aircraft's nose landing gear and left and right main landing gear are statically restrained. At present, the crowbar type is generally used, that is, one end of the crowbar is connected The other end of the dummy wheel of the landing gear is connected with the position control actuator and the stop protection pull plate; the production cycle of this type of fixture is long, and the overall size of the crowbar support is relatively large, which occupies more space and is ...
