    Abstract: A temperature adaptive fluid damping system is provided. One embodiment of the temperature adaptive fluid damping system comprises two fluid chambers, a piston in fluid communication with the fluid chambers, and a fluid path between the fluid chambers. An elastomeric retaining element adjacent to the fluid path is constrained to deform substantially perpendicular to the fluid path, so that the retaining element is operable to vary the cross-sectional area of the fluid path inversely to a change in temperature.

    Abstract translation: 提供了一种温度自适应流体阻尼系统。 温度自适应流体阻尼系统的一个实施例包括两个流体室，与流体室流体连通的活塞以及流体室之间的流体路径。 与流体路径相邻的弹性体保持元件被限制为基本上垂直于流体路径变形，使得保持元件可操作以将流体路径的横截面面积与温度变化相反。

    Abstract: A tiltrotor aircraft (10) includes a fuselage (12), a wing member (18) extending from the fuselage, an engine disposed relative to the wing member and a proprotor (26) mechanically coupled to the engine. The proprotor includes a plurality of proprotor blade assemblies (28) each including a spar (40) and a sheath (52) extending spanwise along the spar forming the leading edge (48) of the proprotor blade assembly. The spar has a root section (42), a main section (44) and a tip section (46). The spar has a generally oval cross section at radial stations along the main section and a first edge having a structural bias relative to a generally oppositely disposed second edge at the radial stations along the main section.

    Abstract: Systems (50), methods (200) and non-transitory computer readable storage media (80) for airspace management within an airspace region (10) at a node (52, 54, 56, 58) of a peer to peer network having a plurality of nodes (52, 54, 56, 58) and maintaining a blockchain (100) containing a current deconflicted flight schedule for the airspace region (10). One method (200) includes receiving (202) requests for airspace reservations, each including flight plan data, from other nodes over the peer to peer network, compiling (204) the flight plan data to identify (206) conflicts between the requests and the current deconflicted flight schedule, validating (210) the flight plan data of the requests that do not conflict with the current deconflicted flight schedule to generate validated airspace reservations, creating (212) a block containing the validated airspace reservations and interlinking (214) the block with the blockchain such that the blockchain contains a new deconflicted flight schedule for the airspace region for broadcast (216) to the other nodes over the peer to peer network.
