Insect-imitating double-wing flapping-amplitude-variable mechanical flapping-wing air vehicle

The invention discloses an insect-imitating double-wing flapping-amplitude-variable mechanical flapping-wing aircraft. The insect-imitating double-wing flapping-amplitude-variable mechanical flapping-wing aircraft comprises a fuselage skeleton, a wing assembly with a front wing and a rear wing, and a fuselage muscle assembly which is located in the fuselage skeleton, connected with the wing assembly and used for driving the front wing and the rear wing to flap. The front wing muscle assembly is connected with the wing assembly and used for changing the flapping amplitude of a front wing, the rear wing muscle assembly is connected with the wing assembly and used for changing the flapping amplitude of a rear wing, and the head power assembly is located at the head of the fuselage framework, connected with the fuselage muscle assembly and used for generating power to the fuselage muscle assembly. The flapping phase, the flapping amplitude and the flapping frequency of the front wing and the rear wing can be chan
