Embodiment 1

[0022] figure 1 It is a side sectional view of the ejection rocket deicing and fire extinguishing system in Embodiment 1 of the present invention, figure 2 It is a perspective view of the ejection rocket deicing and fire extinguishing system in Embodiment 1 of the present invention; this embodiment takes the layout of a two-stage ejection rocket as an example. Such as figure 1 As shown, the deicing and fire extinguishing system includes a bleed air hood 1 , an ejector rocket combustion chamber, a nozzle 7 , a supply pipeline system 4 , a fuel storage tank 5 and an oxidant storage tank 6 .

[0023] The air-entraining cover 1, the ejection rocket combustion chamber and the nozzle 7 are sequentially connected.

[0024] Two stages of ejector rockets are arranged in the ejector rocket combustion chamber, including center rocket 2 and wall rocket 3, arranged front and back. The "center" and "wall" described in the text refer to the position of the rocket. The central rocket 2 c...

Embodiment 2

[0029] see Figure 4 , in this embodiment, there are multiple combustion chambers connected in parallel, multiple combustion chambers form multiple passages, and each passage is provided with rockets of one or more stages. A plurality of combustion chambers share the bleed hood 1 and the nozzle 7.

Embodiment 3

[0031] see Figure 5 , In this embodiment, the expansion section 8 is connected after the nozzle. The outlet of the expansion section is as large as possible, thereby increasing the contact area between the airflow and the deicing target. If the outlet of the nozzle 7 is circular, the expansion section 8 adopts a circle-to-square expansion section.

[0032] An ejection rocket deicing and fire extinguishing system provided by an embodiment of the present invention innovatively introduces rocket ramjet technology into the field of deicing and fire extinguishing, and realizes a deicing and fire extinguishing equipment with simple structure, high efficiency and easy maintenance. The ejection rocket deicing and fire extinguishing system of the present invention can work under various environmental conditions, and has no requirement on the air in the external environment, and the normal ignition work of the system is not affected by rainy, snowy or windy sand weather.

Abstract

The invention discloses a rocket ejection deicing and fire extinguishing system. According to the system, the rocket ramjet combined engine technology is applied to deicing and fire extinguishing scenes, and an efficient and convenient deicing and fire extinguishing system solution is provided. In the system, an air entraining cover, a rocket ejection combustion chamber and a spray pipe are sequentially connected, and a fuel storage tank and an oxidant storage tank are connected with a rocket in the ejection rocket combustion chamber through a supply pipeline system; the air entraining cover is designed to be horn-mouth-shaped, and the spray pipe is a contraction section.

Description

technical field [0001] The invention relates to the technical field of rocket ramjet combined engines, in particular to an ejection rocket deicing and fire extinguishing system. Background technique [0002] Our country has a vast territory and a changeable climate. The temperature in the north is low in winter, and roads and airports often freeze after snowfall. In some areas in the south of my country, freezing rain also occurs in winter, which has a huge impact on transportation. In the face of large-scale deicing problems on roads and airports, the existing deicing equipment such as chemical reagent dissolution and mechanical vehicle deicing efficiency are often not high. The deicing vehicle designed by retrofitting an aero turbine engine can quickly deicing through high-temperature gas. Ice and snow are melted and blown off, and the efficiency is high, but the maintenance of aero-engine equipment is complicated and the cost of use is high. On the same principle, aero-e...
