    • A novel design and construction method for an inflatable, rigidizable wing for a terrestrial or planetary flying vehicle. The wing is caused to deploy from an initially packed condition and to assume its functional shape by means of an inflation gas. After inflation, the wing is rigidized by any of several means, such that the inflation gas is no longer required. The composite wing is fabricated from a base reinforcement material, often a fabric, which is coated with a polymer resin that hardens when exposed to a curing mechanism. Several activation mechanisms exist by which to initiate rigidization of such a structure, including elevated temperature, ultraviolet light, and chemical constituents of the inflation gas. The resultant wing has fundamental advantages compared to existing inflatable wings, including improved stiffness, and reduced susceptibility to structural failure in response to puncture.
    • 一种用于陆地或行星飞行器的可充气,可固定翼的新颖设计和施工方法。 使机翼从初始包装状态部署,并通过充气气体承担其功能形状。 在膨胀之后,机翼通过几种手段中的任何一种来固定,使得不再需要膨胀气体。 复合翼片由基底增强材料制成,通常是织物,其涂覆有当暴露于固化机构时硬化的聚合物树脂。 存在几种启动机制,其通过其启动这种结构的刚性化,包括升高的温度,紫外线和膨胀气体的化学成分。 所得到的翼片与现有的充气翼相比具有基本的优点,包括改善的刚度,以及降低响应于穿刺的结构失效的敏感性。

    • A helicopter blade position and control mechanism including a hollow rotor shaft for mounting a plurality of rotor blades with provision for pitch adjustment. A control shaft is disposed within the rotor shaft and is rotatable relative thereto and is associated with actuators for the blades such that the pitch of the blades is changed when the control shaft rotates relative to the rotor shaft. A planetary gear assembly interconnects the control shaft and a source of power fixed to the helicopter fuselage and is such that when an input to the planetary gear assembly is quiescent, the control shaft will rotate in the same direction and at the same rate as the rotor shaft to maintain a desired blade pitch. Conversely, when an input is placed on the planetary gear system, relative rotation between the control shaft and the rotor shaft will occur to provide the desired adjustment in blade pitch. The system allows accurate blade position feedback signals to be taken from a feedback device stationarily mounted on the fuselage.
    • 一种直升机叶片位置和控制机构,包括用于安装多个转子叶片的中空转子轴,用于调节桨距。 控制轴设置在转子轴内并且可相对于其转动并与叶片的致动器相关联,使得当控制轴相对于转子轴转动时叶片的间距改变。 行星齿轮组件将控制轴和固定到直升机机身的动力源相互连接,并且使得当行星齿轮组件的输入静止时,控制轴将以与转子相同的方向和速度旋转 轴以保持期望的叶片间距。 相反,当输入被放置在行星齿轮系统上时,将发生控制轴和转子轴之间的相对旋转以提供叶片间距期望的调节。 该系统允许从固定安装在机身上的反馈装置获取精确的刀片位置反馈信号。

    • The compound helicopter is a hybrid combination of a helicopter and a fixed wing aircraft. A conventional helicopter is modified with a nose-mounted tractor propeller to provide thrust for forward flight. Wings are added to provide lift during forward flight. With the propeller providing thrust and the wings lift during forward flight, the helicopter rotor blades are unloaded during cruising flight to allow increased forward speed by avoiding limitations of conventional helicopters, including retreating rotor blade stall and maximum rotor blade tip speeds. A single powerplant drives both the main rotor and the nose-mounted propeller. The compound helicopter employs high aspect ratio wings with large flaps that may be extended to reduce vertical drag during vertical flight and hovering operations.
    • 复合直升机是直升机和固定翼飞机的混合组合。 传统的直升机用鼻梁式拖拉机螺旋桨改装,以提供向前飞行的推力。 在向前飞行期间添加翼来提供电梯。 螺旋桨在向前飞行期间提供推力和机翼升力,直升机转子叶片在巡航飞行期间卸载,以避免传统直升机的限制,包括撤回转子叶片失速和最大转子叶片叶尖速度,从而提高向前速度。 单个动力装置驱动主转子和鼻安装的螺旋桨。 复合式直升机采用高长宽比的翼片,可以扩展大型翼片,以减少垂直飞行和悬停操作中的垂直阻力。
