Embodiment 1
[0037] like figure 2 A dual-factor linkage trigger switch device is shown, which has a torque loader 2-10 and a corner trigger 2-20, wherein, as shown in FIG. figure 2 As shown, the torque loader 2-10 includes an action cylinder housing 2-4 and a piston limit nut 2-3 threaded at the port of the action cylinder housing 2-4. The action cylinder housing 2-4 There is a medium cavity and a moment loading piston 2-5. The moment loading piston 2-5 includes a piston head and a piston rod, and a sealing rubber ring 2-1 is arranged on the peripheral side of the piston head. The moment loading piston 2 The piston rod of -5 passes through the piston limit nut 2-3 and is connected to the linkage switch assembly. Between the torque loading piston 2-5 and the piston limit nut 2-3, a Piston return spring 2-2, the medium cavity of the torque loader 2-10 communicates with an external pressure source, and controls the extension or retraction of the piston rod with the pressure increase or pre...
Embodiment 2
[0061] The difference from Embodiment 1 above is that in this embodiment, the two-factor linkage trigger switch device can also be applied to prevent the pitch stall of the aircraft, and the system is suitable for models with different stall speeds and stall elevation angles; At the flight speed, it has the function of preventing the pitching stall of the aircraft.
[0062] like Figure 8 As shown in the figure, the corner trigger 2-20 is connected with the aircraft steering stick, and the linkage relationship between the steering stick and the corner trigger 2-20 is: when the steering stick is pushed, the corner trigger 2-20 rotates clockwise; when the steering stick is pulled, the corner The trigger turns counterclockwise.
[0063] The nozzle of the moment loader 2-10 is connected with the aircraft pitot tube to feel the static pressure of the aircraft pitot tube.
[0064] The trigger switch 2-11 and the trigger switch 2-12 are respectively connected to the horizontal stab...
