铍空心体太阳帆：太阳引力焦点和内部奥尔特云的探索
The beryllium hollow-body solar sail: exploration of the Sun's gravitational focus and the inner Oort Cloud
摘要：
研究了充氢铍空心体星际太阳帆在太阳辐射压加速过程中的航天器运动学、近日点峰值温度和空间环境效应。我们表明，扩散减轻了板上填充气体储备和静电压力可以减轻近日点距离的增加。对于0.1天文单位的近日点，一个半径为937米的帆，帆质量为150公斤，有效载荷质量为150公斤，近日点帆温度约为1000 K，峰值加速度约为0.6 g，太阳系出口速度约为400 km/s。在帆展开后，飞船在2.5年内到达200 AU的太阳风层顶，太阳的内部引力集中在550 AU，大约6.5年，30年内到达2，550 AU。Be空体帆可以在2040年后的时间框架内应用，以验证广义相对论关于太阳内部引力焦点的预测，并探索太阳内部奥尔特彗星云中的粒子和场。
英文摘要：
Spacecraft kinematics, peak perihelion temperature and space environment effects during solar-radiation-pressure acceleration for a beryllium hollow-body interstellar solar sail inflated with hydrogen fill gas are investigated. We demonstrate that diffusion is alleviated by an on-board fill gas reserve and electrostatic pressure can be alleviated by increasing perihelion distance. For a 0.1 AU perihelion, a 937 m radius sail with a sail mass of 150 kg and a payload mass of 150 kg, perihelion sail temperature is about 1000 K, peak acceleration is about 0.6 g, and solar-system exit velocity is about 400 km/s. After sail deployments, the craft reaches the 200 AU heliopause in 2.5 years, the Sun's inner gravitational focus at 550 AU in about 6.5 years and 2,550 AU in 30 years. The Be hollow-body sail could be applied in the post 2040 time frame to verify general relativity predictions regarding the Sun's inner gravitational focus and to explore particles and fields in the Sun's inner Oort Comet Cloud.
