Abstract

The invention discloses an instruction and warning system of a water rudder control system of a large amphibious aircraft. The instruction and warning system is characterized in that a water rudder control computer (101) acquires the water rudder deflection angle acquired by a feedback sensor in real time, the feedback sensor (102) acquires the deflection angle of a water rudder, a GPS (103) acquires a ground speed signal of the aircraft in real time, an atmosphere data computer (105) acquires an air speed signal, a radio altimeter (106) acquires the height of the aircraft away from the groundor the water surface, a take-off and landing wheel load annunciator (107) acquires an undercarriage front take-off wheel load signal, a warning lamp (108) is used for giving a warning visual instruction, a displayer (109) displays a water rudder deflection angle instruction and the maximum deflection limit angle, an intra-aircraft verbal system (110) is used for giving an auditory instruction, acombined hydraulic valve (111) is used for driving the water rudder to act and providing power, a control actuator (112) is used for controlling collection, release and deflection of the water rudder,and a system processor (104) receives data of the water rudder control computer (101) and obtains the water rudder deflection angle and the water rudder deflection angle limit angle at the current speed.

Description

technical field [0001] The invention relates to the field of avionics system design, in particular to an indication and warning system of a water rudder control system used when a large amphibious aircraft taxis on the water surface. Background technique [0002] The water rudder control system is the control device used to control the direction of the aircraft when taxiing on the water surface. The water rudder control system should be able to control the water rudder to deflect according to the predetermined deflection law under the control of the pedals, and keep the movement of the front wheel turning and rudder Consistency, pedal forward with the left foot, the water rudder deflects to the left; pedal forward with the right foot, the water rudder deflects to the right. When the water rudder control system is powered off, the system can automatically return to the neutral position and lock; after the aircraft ground speed exceeds 70km / h, the water rudder control system d...
