The working principle of the jet pipe of the application is described in detail with reference to the accompanying drawing：
As shown in Fig. 2, when turboshaft engine initial start or small-power are run, due to the stream of the tail gas of engine emission
Amount, speed, pressure etc. are smaller, and the requirement that jet pipe can generate electricity also is not achieved in condition at this time, at this point, pressure-regulating valve 11 is opened,
The tail gas of turboshaft engine is guided directly into the by-pass air duct of turboshaft engine by pressure-regulating valve 11, then passes through spout
Flow out engine.
As shown in figure 3, when turboshaft engine reaches rated operation, in the stream of the tail gas of turboshaft engine discharge
Amount, speed and pressure just reach the jet pipe generate electricity required operating condition when, i.e. the pressure of air-flow that is subject to of piston 6
(as shown in the figure to the right) is just greater than permanent magnet 3 suffered by piston to its suction (as shown in the figure to the left), spring 8 to its reprimand
Power (as shown in the figure to the left) and connecting rod 13 are to the resultant force of its thrust (as shown in the figure to the left), at this point, pressure-regulating valve 11 closes
It closes, the tail gas of engine emission starts that piston 6 is pushed to move right, so that piston 6 leaves left stop limit platform 4.Permanent magnet 3 is right
The suction of piston 6 can be reduced rapidly with the increase of distance between the two, this is a typical non-linear force.Piston 6
After being forced to leave equilibrium state, piston 6 drives connecting rod 13 to move under the promotion of left side stream pressure, and connecting rod 13 drives straight again
Line generator 9 works, so that linear electric generator 9 be made to generate electricity.
When piston 6 moves right to certain position, exhaust outlet 12 on jet pipe intension casing 2 be located at spring branch
Exhaust outlet 14 on frame 7 can automatically open, and the tail gas of engine emission is discharged rapidly by the two exhaust outlets, so that piston 6
The gas pressure moment in left side reduces, and repulsion of the suction of permanent magnet 3 suffered by piston 6, spring 8 etc. is much larger than air-flow at this time
Pressure, therefore piston 6 starts to move downward after reaching right stop limit platform 5, with distance between piston 6 and permanent magnet 3
Reduction, permanent magnet 3 can increase rapidly the suction of piston 6, and piston 6 continues to move downward, until reaching left stop limit platform
4.Equally, in this process, piston 6 will drive the movement of connecting rod 13, and connecting rod 13 drives linear electric generator 9 to work, thus
Linear electric generator 9 is set to generate electricity.
Piston 6 will repeat the process of linear reciprocating motion recited above.In this process, air-flow pushes 6 institute of piston
