Ventilation pressure relief structure of fairing
Ventilation pressure relief structure of fairing
The invention provides a ventilation pressure relief structure of a fairing and relates to the field of structural designing of aircrafts. The ventilation pressure relief structure is used for ventilation pressure relief of an aircraft fairing (1). A hole matched with a ventilation tube (3) is formed in the fairing (1), and the wall of the hole is coated with room-temperature curing adhesive (5); the ventilation tube (3) is of a broken-line tubular structure, one end of the ventilation tube (3) is inserted in the hole in the fairing (1), and the part, arranged outside the fairing (1), of the ventilation tube (3) is supported and fixed to the outer surface of the skin of the fairing (1) through a paper honeycomb core (4); a glass fabric skin (2) is cured on the outer surface of the skin of the fairing (1) together with the honeycomb core (4) and the ventilation tube (3). The ventilation pressure relief structure of the fairing is convenient to manufacture and simple in structure, the inside and the outside of the fairing (1) are communicated through arranging the ventilation tube on the fairing, the pressure difference inside and outside the fairing is reduced, the fairing is guaranteed not to bear additional load caused by pressure difference, the sealing performance is good, the stability of the device is greatly improved, and safety and reliability are realized.
