Wing test piece and processing method thereof

Abstract

The invention relates to a wing test piece and a processing method thereof. The test piece comprises a spar which comprises an upper margin plate, a lower margin plate parallel to the upper margin plate, and a web plate vertically connected between the upper margin plate and the lower margin plate, wing ribs which comprise end ribs arranged at the two ends of the spar respectively and a plurality of middle ribs evenly distributed in the length direction of the spar, skin and wing-shaped foams, wherein the end ribs and the middle ribs are fixedly connected with the spar and are perpendicular to the spar; the skin wraps the outer sides of the spar and the wing ribs; the wing-shaped foams are a plurality of independent unit bodies and are respectively filled in each closed space formed by the spar, the wing ribs and the skin; the two ends of the spar respectively protrude out of the corresponding end ribs, and the first end of the spar is used for being connected with a test tool; and a first loading connector is arranged at the second end of the spar and used for being connected with a loading system. The wing test piece provided by the invention can meet the flexibility required by a deformation test, does not need to generate an additional mold, and has the advantage of low processing cost.

Description

technical field [0001] The present application relates to the technical field of aircraft wing performance detection, in particular to a wing test piece and a processing method thereof. Background technique [0002] The wings of the aircraft will bend and deform during flight, which may affect the safety status of the aircraft. Therefore, the deformation monitoring of the aircraft wings is very necessary, and the deformation monitoring of the aircraft wings is realized through sensors. When developing the deformation monitoring sensor, it is necessary to use the wing test piece as the basic platform for test verification. The sensor is pasted and fixed on the wing test piece, and the load is applied to deform the wing test piece. The shape of the test piece is monitored by the sensor. Variables, and then test and verify the performance of the sensor. [0003] At present, the wing test pieces used for deformation monitoring sensor testing mainly come from the wings of mature...
