After the fairing on the power cabin of the current helicopter is opened, it is basically the same height as the power platform of the power cabin. When maintaining the main reducer, engine and other components in the power cabin, it is necessary to bend down, which is very inconvenient and affects the maintenance efficiency; in addition, The size of the current fairing is relatively large. If it is used as a stepping platform, a large bending moment will be generated when the staff steps on it. The structure is not stable enough, and there is a certain danger. Moreover, the large size makes it difficult to open the fairing during the opening process. Will sweep over a large area and will easily collide with other structures on the helicopter

The invention belongs to the technical field of structural design of helicopter engine compartment cowlings, and particularly relates to a foldable cowling. The foldable cowling comprises a foldable plate, a cover plate and one or more connecting rods, the edge of one side of the foldable plate is a connecting edge, and the edge of the side, opposite to the connecting edge is a foldable edge; theedge of one side of the cover plate is a rotating edge which is hinged to the foldable edge; the cover plate is divided into two segments, one segment is in an arc shape and is called an arc-shaped segment, and the other segment is flat and straight and is called a flat and straight segment; the rotating edge is the edge of the side, away from the arc-shaped edge, of the flat and straight segment;one end of each connecting rod is a connecting end, the other end of each connecting rod is a foldable end, and the foldable ends are hinged to the inner surface of the arc-shaped segment. The invention further relates to a helicopter with the foldable cowling.
Description
technical field [0001] The application belongs to the technical field of structure design of a helicopter power cabin fairing, and in particular relates to a foldable fairing and a helicopter with the same. Background technique [0002] The main reducer, engine and other components in the helicopter power cabin need daily maintenance. When performing maintenance, the fairing on it needs to be opened first. In order to improve work efficiency, the staff directly use the opened fairing as a stepping stone during maintenance. platform, and no longer build a special stepping platform for this purpose. After the fairing on the power cabin of the current helicopter is opened, it is basically the same height as the power platform of the power cabin. When maintaining the main reducer, engine and other components in the power cabin, it is necessary to bend down, which is very inconvenient and affects the maintenance efficiency; in addition, The size of the current fairing is relativ...
