Embodiment 1

[0030] figure 1 It is the left view of the pod retractable mechanism, figure 2 is the top view of the pod retractable mechanism, such as figure 1 and figure 2 As shown, the present embodiment provides a flexible towing pod retractable mechanism, the pod retractable mechanism is installed on the aircraft shell 14, and the pod retractable mechanism includes a driving winch 1, a suspension cable 2, an overload Automatic cut-off device 4,

[0031] One end of the suspension cable 2 is wound on the drive winch 1, the other end of the suspension cable 2 passes through the overload automatic cut-off device 4, and is fixedly connected with the pod 8;

[0032] image 3 is a detailed view of the overload automatic cut-off device 4, such as image 3 As shown, the overload automatic cut-off device 4 includes a front bracket 9, a first guide pulley 12 and a friction lock 13; the front bracket 9 is fixedly connected with the aircraft shell 14, and the front bracket 9 is provided with ...

Embodiment 2

[0039] This embodiment provides a flexible towing pod retraction method, using the above-mentioned pod retraction mechanism, the method includes:

[0040] Normal retractable pod: Before the aircraft performs its task, the driving winch 1 is reversed, the suspension cable 2 wound on the driving winch 1 is loosened, and the pod 8 connected by the suspension cable 2 is slowly lowered under the action of gravity, and the Suspender 2 is towed behind the aircraft. Before the aircraft returns to land after the mission is completed, the winch 1 is driven to rotate forward, the suspension cable 2 on the drive winch 1 is wound up, and the pod 8 connected by the suspension cable 2 is slowly retracted under the torque force transmitted by the transmission mechanism. Lift it up, put it in the outer pylon of the fuselage, and drive the mechanical device to lock the pod 8 by manipulating the locking mechanism 6.

[0041]Under abnormal conditions: when the pod retractable mechanism is workin...

Abstract

The invention provides a flexible dragging pod folding and unfolding mechanism. The flexible dragging pod folding and unfolding mechanism is mounted on an airplane shell 14, and comprises a drive winch 1, a suspension cable 2 and an overload automatic cutting-off device 4, one end of the suspension cable 2 is wound on the drive winch 1, the other end of the suspension cable penetrates through theoverload automatic cutting-off device 4 and is fixedly connected with a pod 8, the overload automatic cutting-off device 4 comprises a front support 9, a first guide pulley 12 and a friction lock 13,the front support 9 is fixedly connected with the airplane shell 14, a chopping-off groove 11 is formed in the front support 9, a tool is arranged in the chopping-off groove 11, one end of the friction lock 13 is fixed to the airplane shell 14, the other end of the friction lock 13 is fixedly connected with the first guide pulley 12, and the friction lock 13 is broken under the determination loadeffect. Throwing of the pod under the remote dragging and emergency conditions can be achieved.

Description

technical field [0001] The invention belongs to the technical field of retractable pods of aviation, and in particular relates to a retractable mechanism of flexible towed pods. Background technique [0002] The airborne electromagnetic measurement system of a time-domain aircraft usually hangs a transmitting coil composed of one or more turns of cable under the left and right wing tips of the aircraft and on the front and rear fuselage brackets, and the transmitter provides pulse current to the transmitting coil, thereby Generate a strong pulsed primary electromagnetic field in the surrounding space. The receiving coil is installed in the pod towed under the rear of the aircraft, and measures the horizontal component of the secondary field or all the three components of the space generated by the excitation of the underground anomalous body during the interval of the transmission pulse. By studying the change of earth resistivity, the distribution of underground abnormal b...
