The invention discloses a deepwater aircraft speed detection and self-energy supply system which comprises a flow guide cap and a shell. A current generation assembly, a connecting ring with a wire hole, a conducting ring, a speed detection circuit and an energy collection circuit with a capacitor are arranged in the shell. The current generation assembly comprises a central shaft, a piezoelectric rotor, a propeller and a bearing assembly, and the piezoelectric rotor is fixed on the central shaft; the propeller is fixed to the piezoelectric rotor, piezoelectric ceramic pieces are distributed on the outer side of the piezoelectric rotor, and PTFE small balls are distributed between the adjacent piezoelectric ceramic pieces. The propeller drives the piezoelectric rotor to rotate under the action of water flow, and then the PTFE small ball is driven to collide with the piezoelectric ceramic piece to generate current and transmit the current to the speed detection circuit to recognize the speed of the aircraft. The energy collection circuit converts the current and stores the electric energy into the capacitor. Self-energizing and speed detection of the deepwater aircraft are carried out through water flow, the technical problem that a large number of speed sensors are adopted at present is solved, and the working stability of the aircraft is improved.
