摘要
气液压发射起飞是近年来国际上出现的一种先进的无人机发射方式,适用于中小型无人机的发射起飞。原理试验研究为无人机气液压发射技术的应用研究提供试验基础,并为发射装置的工程研制提供设计依据。气液压发射是将气压储能与液压传动相结合以产生作用力,使无人机加速至起飞速度。以滑车为无人机的模拟试验件进行原理试验,并对蓄能器油压、钢丝绳牵引力、滑车速度等参数进行动态测量,试验结果表明,气液压发射原理切实可行,增加充油压力能明显增大发射装置的做功能力。气液压发射原理在工程应用中进一步得到有效验证。
The takeoff by hydraulic and pneumatic launching（HPL） is an international advanced launching method for unmanned aerial vehicle（UAV）.It is suitable for launching of medium-sized and pint-sized UAV.The foundation is offered for HPL technology on principle experiments.Moreover,the design base is offered for engineering development of the launching equipment.HPL technology is to produce power combining pneumatic energy with the hydraulic transmission,so that UAV can be accelerated to takeoff velocity.The principle experiments are accomplished using a shuttle as the simulation experiment part of UAV.Some parameters,such as accumulator oil pressure,steel cable pull and shuttle velocity are dynamically measured.Results show that the principle of the launch technique is feasible.And the power of the launch equipment can be advanced by increasing oil pressure.The HPL principle is validated in engineering application.
