摘要
无人机航空物探具有效率高、成本低、风险小、不受地形条件及人为因素影响等优点,但航放晶体的有效挂载是目前无人机集成安装面临的主要问题。为了满足航放晶体安装空间要求及工作环境要求,本文提出了一种基于无人机的航放晶体吊舱装置,能够使航放晶体安全地挂载在无人机上并稳定地工作。针对前后整流罩的气动外形设计,可极大地减少晶体箱的空气阻力,使系统作业时的航程与航时更长,进行轨迹控制时的响应更快;通过对晶体箱内部的海绵填充,为晶体提供了缓震和保温的环境,使航放晶体在温度变化较快、震动较大的恶劣条件时仍然可以稳定工作。因此,本文提出的无人机航空物探航放晶体吊舱装置既能够解决无人机机身安装空间有限等问题,又能够有效减少撞击、震动、低温等对晶体带来的影响,保证日常作业的顺利进行,可广泛应用于航空物探作业领域。
UAV aerogeophysical exploration has the advantages of high efficiency,low cost and low risk,and it will not be affected by terrain conditions and pilots.However,how to effectively mount the crystal is the biggest problem.In order to satisfy the space requirement and working environment requirement of the crystal installation,this paper presents a design of crystal pod device for UAV aerogeophysical exploration,which can make the crystal safely mounted and work on the UAV.The design of aerodynamic shape for front and rear fairs could reduce the air resistance,lengthen endurance and flying range and faster accelerate the response of trajectory control.By filling the sponge inside the crystal box,the shock can be obviously mitigated and the temperature can be easily maintained.The sponge can guarantee the crystal work steadily under severe conditions with large vibration and extreme temperature.Therefore,the crystal pod device proposed in this paper can not only solve the problem of limited installation space of UAV fuselage,but also effectively reduce the impact of vibration and low temperature.Which can be widely used in the field of aerogeophysical exploration.
