    • Some embodiments described herein relate to an aircraft that includes a support frame, at least one gas compartment, and multiple propulsion units. The gas compartment(s) can be coupled to the support frame and configured to contain a gas having a gas density less than the density of atmospheric air surrounding the aircraft during operation. Similarly stated, the gas-filled gas compartment(s) can produce a gas lifting force on the support frame. The propulsion units can each be configured to selectively produce a propulsive force with a thrust vector with a non-zero component along a vertical axis of the support frame. The maximum gross weight of the aircraft can be greater than either the gas lifting force of the maximum vertical propulsion force and less than the sum of the gas lifting force and the maximum vertical propulsion force.
    • 这里描述的一些实施例涉及一种包括支撑框架,至少一个气体隔室和多个推进单元的飞行器。 (一个或多个)气体隔室可联接到支撑框架并被构造成容纳气体密度小于操作期间飞机周围的大气密度的气体。 类似地指出,气体填充气体隔室可以在支撑框架上产生气体提升力。 每个推进单元可以构造成选择性地沿着支撑框架的竖直轴线产生具有非零分量的推力矢量的推进力。 飞机的最大总重量可以大于最大垂直推进力的气体提升力,并且小于气体提升力和最大垂直推进力的总和。
