the control system automatically regulates the buoyancy force of the gasbag according to parameters of a sensor, so as to achieve the gravity balance and energy-saving flight of the whole aircraft.
控制系 统根据传感器参数自动调节气囊的浮升力,达到整机的重力平衡和节能飞行。
the double piezometer is made of organic glasses and rubber membranes. it can not only directly shows the interior pressure in liquid, but also can be used in the buoyancy force related experiments.
