摘要： A projecting apparatus and a projecting method, relates to the field of projecting technologies. The projecting apparatus includes: a light source (1), a projection film (2) and a lens (3), wherein the projection film (2) and the lens (3) are both located in a light path of the light source (1), a focal length of the lens (3) is greater than 0, and a positional relationship between the light source (1) and the lens (3) satisfies a formula: 0 ≤ E ≤ ( 2 1 6 D ) 0 . 8 , wherein E is a distance between the light source and the lens in centimeters; D is the focal length of the lens in centimeters, which solves the technical problem of high costs of 3D protection in the prior art, and can project a pattern on the projection film into a three-dimensional stereo image.

摘要： A remote-control aircraft comprises an aircraft body with a mounting platform provided with a connecting part and first magnet(s), and the connecting part is perforated with a connecting hole; and comprises an aircraft wing with an inserting part and second magnet(s) on its underside close to the aircraft body, the inserting part is rotationally inserted into the connecting hole, the second magnet and the first magnet are connected by magnetic attraction, and the aircraft wing is in close contact with the mounting platform. Thus, the aircraft wing and body can be quickly assembled and disassembled and can be carried conveniently. While the aircraft wing collides with an obstacle, it can be rotated around the inserting part as the center, and the impact force can be unloaded by rotating to prevent the aircraft wing from being damaged and prevent the aircraft wing from being separated from the aircraft body.
