Abstract

The invention discloses a solid smoke puller, which comprises a front fairing (1), a cylinder body (2), a smoke bomb (8) and a rear fairing (4), and the cylinder (2) is respectively connected to the front fairing ( 1) It is connected with the rear fairing (4), and a plurality of smoke bombs (8) are fixedly connected in the cylinder (2) and arranged in series. There is a through hole in the center of the smoke bomb (8), and the through hole forms the center The flow channel (13), the through hole communicates with the smoke outlet of the smoke bomb (8), the front fairing (1) is provided with a flow channel connected to the atmosphere, and communicates with the central flow channel (13), the rear fairing (4 ) is provided with a nozzle device (10), and the center of the nozzle device (10) has a nozzle (14) connected to the central flow channel (13), thus forming a continuous flow channel. When the aircraft is flying, the air forms a stable flow rate in the continuous flow channel. Driven by the airflow, the smoke generated by the smoke bomb (8) is ejected from the nozzle (14) to form a smoke band, which can maintain a good smoke pulling effect.

Description

technical field [0001] The invention relates to a solid smoke puller, in particular to a solid smoke puller used for displaying the flight track of an airplane during an airplane flight show. Background technique [0002] The solid smoke puller is an airborne external device used to display the flight path of the aircraft during the aircraft flight show. The traditional solid smoke puller uses the pressure generated by the combustion of the smoke bombs arranged side by side to directly spray the colored smoke generated by the combustion of the smoke bombs into the air, relying on the speed of the aircraft to drag to form a smoke belt, and then display the flight trajectory of the aircraft. Generally, three smoke bombs are arranged side by side at the end of the solid smoke puller. Although the structure of this solid smoke puller is very simple and easy to maintain, the smoke concentration is greatly affected by the flight speed of the aircraft. The higher the flight speed,...
