Problems solved by technology

[0003] However, there are few airborne electromagnetic detection equipment, and the existing airborne electromagnetic equipment mainly adopts a suspended coil structure, such as a suspended helicopter time-domain aeromagnetic detection pod described in CN201610161194.2, but this type of electromagnetic detection The structure of the equipment is complex, and the volume is large, which has a great impact on the aerodynamics of the helicopter. Especially during the normal flight of the helicopter, it is easily affected by the airflow, with low stability and low detection accuracy.

Embodiment

[0024] Two types of aeromagnetic detection equipment need to be installed on a certain helicopter, one with a combined length of about 3 meters and the other with a combined length of about 1.2 meters. In order to ensure the measurement accuracy of the aeromagnetic measurement equipment, the following strict installation and use requirements are imposed on the magnetic probe rod installed with the aeromagnetic measurement equipment:

[0025] 1. The aeromagnetic measurement task equipment installed at the front end must be more than 6 meters away from the front end of the aircraft nose.

[0026] 2. During the normal flight of the helicopter, the strength and stiffness characteristics must be maintained, and the occurrence of resonance must be avoided to minimize vibration.

[0027] 3. Need to do non-magnetic treatment, and take into account the requirements of lightning protection.

[0028] 4. Easy to disassemble, install and store.

[0029] Therefore, in actual implementatio...

Abstract

The invention belongs to the helicopter structure design technology, and relates to a cantilever magnetic probe rod for a helicopter. The cantilever magnetic probe rod comprises a front-section proberod, a middle-section probe rod, a rear-section probe rod, connecting pieces, a covering cap, a front cover, a rear cover and a pull rod assembly, wherein the front-section probe rod, the middle-section probe rod and the rear-section probe rod are sequentially connected together through connecting pieces, the front cover and the rear cover are arranged at the front end of the front section probe rod and the tail end of the rear section probe rod respectively, covering caps are arranged at openings in a plurality of positions, used for arranging electromagnetic detection equipment, of the frontsection probe rod and the middle section probe rod respectively, and the pull rod assembly connected with a machine body is arranged at the front ends, close to the connecting pieces, of the rear-section probe rod. According to the cantilever magnetic probe rod, the design difficulty of a cantilever structural part with a large length-diameter ratio is solved, the structural weight is reduced, the assembling manufacturability is improved, the machining period is shortened, the cost is reduced, the cantilever magnetic probe rod is connected with a machine body in a bolt connection mode, and rapid mounting, maintenance and dismounting of the probe rod can be achieved.

Description

technical field [0001] The invention belongs to the helicopter structure design technology, and relates to a cantilever magnetic probe rod used for a helicopter. Background technique [0002] In order to meet the needs of marine geological security projects and land and resources surveys, and to meet the customized requirements of the China Land and Resources Air Geophysical Prospecting and Remote Sensing Center for the installation of aeromagnetic survey mission equipment on the AC312E helicopter, it is necessary to install electromagnetic detection on the lower part of the AC312E helicopter belly The equipment is used to perform aeromagnetic detection tasks. [0003] However, there are few airborne electromagnetic detection equipment, and the existing airborne electromagnetic equipment mainly adopts a suspended coil structure, such as a suspended helicopter time-domain aeromagnetic detection pod described in CN201610161194.2, but this type of electromagnetic detection The...
