Abstract: An ornithopter aircraft has a main body. A first wing frame mount and a second wing frame mount are mounted to the main body. A first wing frame is rotably mounted to a first wing frame axle on the first wing frame mount. The first wing frame is configured to rotate relative to the main body and the rotation can be powered. The first wing frame feathers are rotably mounted to the first wing frame at first feather axles and the first wing frame feather rotation can be powered. The first wing frame feathers are configured to rotate relative to the first wing frame and the first wing frame feather rotation can be powered. A second wing frame is configured to be rotably mounted to a second wing frame axle on the second wing frame mount.

Abstract: In one aspect, a system for people to simulate flying motion may include a plurality of supporting posts, one or more control units, and each of the control unit is connected to the user's body through a string, and a sensor is disposed on each string. The sensor can detect the tension change of the string and transmit the signal to the control unit to adjust the tension accordingly. When the user moves the wings, the change of the tension can be detected by the sensor and transmitted to the control unit to further adjust the tension of each string by pulling or releasing the strings to enable the user to enjoy the flying motion.
