Abstract

The invention relates to the technical field of aircraft rudder shaft heat protection design, and in particular relates to a phase change type heat-proof structure of a rudder shaft and an aircraft. The phase change type heat-proof structure of the rudder shaft comprises a rudder shaft body, and a connecting channel is formed in the rudder shaft body; and the heat-proof structure further comprises a phase change energy storage ring which is partially arranged in the connecting channel and is attached to the inner wall of the connecting channel, and the phase change energy storage ring is filled with a phase change material. The heat-proof structure has the advantages that the temperature of the rudder shaft body is reduced while the bearing capacity of the rudder shaft body is considered.

Description

technical field [0001] The application relates to the technical field of aircraft rudder shaft heat protection design, in particular to a phase-change heat protection structure of a rudder shaft and an aircraft. Background technique [0002] With the development of aerospace technology, more and more aircraft are flying at high speed and for a long time in the atmosphere. Due to aerodynamic heating, the temperature of the rudder shaft will become higher and higher due to the heat transfer to the rudder shaft after the temperature of the air rudder surface rises. The heating of the shaft often leads to the heating of the bearing and steering gear, which seriously affects the normal operation of the bearing and steering gear. [0003] At present, the heat protection of rudder shafts used in the field of missiles or rockets mostly adopts passive heat resistance and heat insulation schemes. Due to the generally low mechanical load-carrying capacity of the thermal resistance str...
