Described trailing edge full-height foam adopts full-height PVC foamed sandwich structure.Described trailing edge under covering, trailing edge, covering and trailing edge full-height foam sets the position consistency of breather hole.On described skins front edges and trailing edge under covering intersection, skins front edges and trailing edge on covering intersection, trailing edge under covering and trailing edge covering intersection be bonded with two-layer carbon cloth respectively.
The utility model advantage is compared with prior art:
1, the utility model realizes the dismounting of aileron by dismounting left side connection bearing and the right side connection connected between bearing and wing, skins front edges is closing structure, avoid the skins front edges opening caused for meeting knocked down condition, do not need to arrange lid at connection bearing place or arrange larger exposed gap, ensure that the rigidity requirement of leading edge and the integraty of aileron structure.
2, the skins front edges closing structure that the utility model adopts uses the method for glueing joint to be connected with spar, the common rib of leading edge, left side leading edge ends rib, right side leading edge ends rib, and compared with opening stressed-skin construction, closing structure covering is thinner, and aileron structural weight is reduced, and assembling is simple.
3, the utility model aileron trailing edge by setting air extractor vent on the upper and lower covering of trailing edge and trailing edge full-height foam, air between effective eliminating bonding interface also forms glue nail, ensure that bind strength, solve the bind strength problem that normal temperature secondary large area is gluedd joint, aileron structure manufacturing cost is significantly reduced.
