Exhaust extension pipe

Abstract

The invention provides a smoke discharging extension pipe. The smoke discharging extension pipe is installed on the edge of an original airplane smoke discharging pipe in a sealed manner. The smoke discharging guide of the original airplane smoke discharging pipe is changed through the smoke discharging extension pipe, and after waste gas and heat flow discharged by the original airplane smoke discharging pipe pass through the extension guide of the smoke discharging extension pipe, an inclination angle away from the airplane skin is achieved. The smoke discharging extension pipe has the beneficial effects that the smoke discharging extension pipe is used for being installed on a Cessna208 type airplane additionally provided with an aerial photography window, on one hand, the influences of smoke discharging pipe heat flow to a camera can be avoided, and the aerial photography effect is improved; and on the other hand, the design structure of the smoke discharging extension pipe is reasonable, and adverse effects cannot be caused on the flight performance of an airplane.

Description

technical field [0001] The invention belongs to the technical field of smoke exhaust pipe design, in particular to a smoke exhaust extension pipe. Background technique [0002] At present, for Cessna208 and other types of aircraft, the smoke exhaust pipe is arranged in such a way that it extends from the right side of the engine to the rear of the engine compartment. Therefore, during the flight of the aircraft, the exhaust gas and heat flow from the engine will pass through the smoke The tube drains and spreads to the belly of the plane. In addition, due to considerations such as the aerial photography angle, the aerial photography window is usually installed on the belly of the aircraft, which leads to the following problems: when the camera performs aerial photography operations through the aerial photography window, since the aerial photography window is just in the belly of the aircraft, namely: It is located in the diffusion area of ​​exhaust gas and heat flow. Theref...

Problems solved by technology

In addition, due to considerations such as the aerial photography angle, the aerial photography window is usually installed on the belly of the aircraft, which leads to the following problems: when the camera performs aerial photography operations through the aerial photography window, since the aerial photography window is just in the belly of the aircraft, namely: Located in the diffusion area of ​​exhaust gas and heat flow, therefore, the aerial view of the camera will be affected by exhaust gas and heat flow from the engine, which will cause ripple interference in the aerial image and reduce the quality of aerial photography
