Embodiment Construction
[0019] The following combination Figure 1 ~ Figure 3 , a preferred embodiment of the present invention is described in detail.
[0020] like figure 1 As shown, the fire prevention structure at the tail end of an aircraft with a gas rudder provided by the present invention includes: a protective assembly, fixedly installed at the tail end of the aircraft, and surrounding the outer side of the engine nozzle 3, and is consistent with the shape of the engine nozzle 3 fit; the gas rudder assembly is fixedly installed above the protective assembly, and is covered and arranged on the top of the engine nozzle 3, and conforms to the shape of the engine nozzle 3; wherein, the protective assembly, the gas rudder assembly and the engine nozzle A long and narrow gap-shaped backfire path 8 is formed between the tubes 3, which can quickly extinguish the backfire of the engine entering therein. Therefore, the fireproof structure of the present invention can not only protect the aircraft ta...

The invention relates to an aircraft tail end fire-proof structure with a gas rudder. The aircraft tail end fire-proof structure with the gas rudder comprises a protecting assembly and a gas rudder assembly, wherein the protecting assembly is fixedly mounted on the tail end of the aircraft and arranged at the outer side of an engine nozzle in a surrounding mode and is in fit with the shape of the engine nozzle; and a tempering path in a long and narrow shape is formed between the protecting assembly, the gas rudder assembly and the engine nozzle, so that engine temper enters the tempering path can be quickly extinguished. According to the aircraft tail end fire-proof structure with the gas rudder, not only can an aft cabin and the surface of an aircraft are protected from being directly ablated by the engine temper, but also axial force of jet-flow of an engine can be bore.
Description
technical field [0001] The invention relates to a fireproof structure at the tail end of an aircraft, in particular to a fireproof structure at the tail end of an aircraft with a gas rudder, which can effectively reduce the impact of engine backfire on the tail equipment of the aircraft when the gas rudder surface is deflected, and belongs to the field of aircraft structure design. Background technique [0002] The gas rudder is a thrust vector control device, which is installed in the engine nozzle of the aircraft. By controlling the jet flow direction of the engine, the aircraft can be stabilized or turned quickly. At present, in order to further reduce the weight of the new aircraft, the traditional gas rudder compartment is no longer used, but four independent gas rudder components are installed at the tail end of the aircraft. [0003] When the gas rudder deflects, the engine backfire will directly act on the end face of the aircraft tail section, and may enter the inte...
