Abstract

The invention provides a porthole sealing structure for an aircraft. The porthole sealing structure comprises a composite window frame, outer layer glass and inner layer glass which are arranged sequentially. The outer layer glass is sleeved with a multi-tooth U-shaped sealing ring. The composite window frame, the outer layer glass and the inner layer glass are connected in a fastened mode through screws. The multi-tooth U-shaped sealing ring comprises an outer arm and an inner arm. The screws penetrate through the composite window frame, the outer arm of the multi-tooth U-shaped sealing ring, the outer layer glass, the inner arm of the multi-tooth U-shaped sealing ring and the inner layer glass in sequence. The multi-tooth U-shaped sealing ring is compressed through the screws, so that the outer layer glass and the inner layer glass of a porthole are sealed, and the outer glass and the composite window frame are sealed; and screw heads in the porthole are sealed through sealing plug caps, and accordingly the whole porthole is sealed. Compared with a traditional airliner porthole sealing design, the porthole sealing design has the characteristics of simple structure, convenient detaching and mounting and reliable sealing.

Description

technical field [0001] The invention relates to the field of aviation, in particular to an adjacent space aircraft that requires high sealing reliability of portholes and is easy to maintain, and in particular relates to a porthole sealing structure for aircraft. Background technique [0002] As near space (20-100 kilometers above the ground) has received more and more attention in recent years, there has been an upsurge in the development of near space vehicles, especially the demand for manned near space vehicles, and its portholes The seal design presents new demands. [0003] At present, the operating altitude range of the porthole sealing design of traditional civil aviation passenger aircraft is 10-15 kilometers, which is far from meeting the requirements of manned near-space vehicles. Therefore, it is necessary to develop a new form of porthole sealing design. Contents of the invention [0004] Aiming at the operating altitude range of traditional civil aviation ai...
