Single-wheel dual-brake electronic transmission brake system of aircraft, capable of choosing braking manner

The invention relates to a single-wheel dual-brake electronic transmission brake system of an aircraft, capable of choosing a braking manner. A brake antiskid control system is formed by an aircraft wheel speed sensor, a control box and an electro-hydraulic servo valve; a brake control system is formed by a braking instruction sensor, the control box and the electro-hydraulic servo valve. The electro-hydraulic servo valve responds to an electric current control signal of the control box to output and adjust the braking pressure outputted to a braking aircraft wheel; braking selection is realized through a hydraulic control valve; a hydraulic braking valve is replaced with the braking instruction sensor; and the electro-hydraulic servo valve is a positive gain valve. The single-wheel dual-brake electronic transmission brake system disclosed by the invention is suitable for a single-wheel dual-brake aircraft wheel using a carbon brake; the requirements for selective brake use of the single-wheel dual-brake airc
