Tethered driving device for pod deformation

Abstract

The invention belongs to the technical field of pod auxiliary equipment, and discloses a tethered driving device for pod deformation based on the defects of application of an existing electric actuator and other executing mechanisms and single-rope and double-rope winding and unwinding winch systems in deformable pod deformation. A control system, a motor driving system, four-row electric synchronous winch system, a power supply system and a pulley turning system are fixedly arranged at the corresponding positions of a pod electrical load cabin fixing frame respectively, and the motor driving system is fixedly arranged on the four-row electric synchronous winch system. One end of a steel wire rope is fixedly arranged at the end of the four-row electric synchronous winch system, and the other end of the steel wire rope bypasses four rows of rollers of the four-row electric synchronous winch system, penetrates through the pulley turning system, then penetrates through the interior of a pod synchronous shock absorber and is finally fixed to a pod bottom frame. Stable deformation of a pod body is guaranteed, and meanwhile the mass of the driving system is reduced. The applicability is wide, and the deformation safety is high. The steel wire rope cannot be disordered in the winding and unwinding process. Multiple winches can be well fixed and wound, and the structure is simple and compact.

Description

technical field [0001] The invention belongs to the technical field of pod auxiliary equipment, and in particular relates to a rope driving device for pod deformation. Background technique [0002] The pod refers to a streamlined nacelle section that is installed with certain airborne equipment or weapons and hangs under the fuselage or wing. With the development of aviation technology, airborne pod technology has also made great progress. Generally speaking, airborne pods can be divided into: weapon pods (including aircraft gun pods, aviation rocket pods), reconnaissance pods, fire control pods, and logistics auxiliary pods (refueling pods). [0003] At present, there are few studies on aerostat launch pods in the world, especially there is no precedent for aerostat launch pods with deformable bodies. [0004] At present, various linear electric actuators, steering gears and other actuators are widely used in the aerospace field, and can complete various tasks such as cha...

AI Technical Summary

Problems solved by technology

[0005] However, for some special flight scenarios where electric actuators cannot complete specific tasks, it is necessary to use lightweight transmission, long-distance transmission, synchronous transmission, and flexible transmission. Range body deformation, the transmission mechanism is difficult to achieve long-distance transmission, synchronous transmission, and the increase in stroke angle has brought about a substantial increase in mass. At the same time, the traditional transmission method is difficult to achieve one-way flexibility, which cannot meet the one-way deformation requirements of the cabin landing buffer

[0006] At present, most of the various winch systems are single-rope or double-rope towing, and there is little research on the multi-rope synchronous retractable winch system, especially the multi-rope synchronous drive winch system in the pod. It is necessary to use a multi-rope synchronous retractable winch system to complete long-distance, large-scale, and lightweight synchronous transmission. Therefore, a multi-rope synchronous retractable winch system is urgently needed to complete the simultaneous deformation of the deformable pod body and the one-way flexible task of landing buffer
