Aircraft door with noise reduction structure
The present invention relates to an aircraft door having a noise reduction structure, comprising: a metal bottle for holding a gas; a rupture disc that closes the gas discharge port and opens the discharge port by rupture due to an external impact; a discharge block in which a rupture needle formed therein pierces the rupture piece to discharge the gas from the metal bottle; an actuator in which a piston is inserted and mounted so as to be capable of reciprocating along the internal space, an actuator shaft is formed so as to extend from the piston, and a relief valve for discharging the gas transmitted from the discharge block to the outside; a damper for controlling the damping force of the aircraft door, a damper shaft being attached to the actuator shaft so as to operate in accordance with the reciprocating motion of the actuator shaft, and a bypass valve forming a bypass flow path necessary for the flow of internal oil; the actuator includes: a piston; an actuator shaft having a hollow interior and provided with a gas discharge nozzle; a slit that perforates the interior and exterior of the actuator shaft; and an outer cover which has a through-hole in the center thereof, communicates with the gas discharge nozzle, and is capable of discharging the gas.
本发明涉及一种具有降低噪声结构的航空器门，包括：金属瓶，保管气体；破裂片，封闭气体的排出口，因外部冲击而破裂并打开排出口；吐出块，在内部形成的破裂针刺破破裂片，使气体从金属瓶吐出；致动器，活塞以能够沿内部空间往复运动的方式插入安装，致动器轴在活塞上延长形成，安全阀将从吐出块接受传递的气体排出到外部；缓冲器，控制航空器门的阻尼力，缓冲器轴与致动器轴连接安装，随着致动器轴的往复运动而运转，旁通阀形成供内部油流动所需的迂回流路；致动器包括：活塞；致动器轴，内部为中空形态，具备气体吐出喷嘴；缝隙，使致动器轴的内外部穿孔；外部罩，在中心部具备通孔，与气体吐出喷嘴连通而能够使气体排出。
