A self-righting gutter system for a structure. Supports mounted to the structure support a gutter. The gutter can rotate from a first water collecting position to a second cleaning position and self-rights to the first water collecting position. The gutter has a greater thickness along a longitudinal axis thereof. The gutter may be rotated, for example, by using a cable, connected to the gutter or by using a properly weighted pole with a hook by standing on the ground. The gutter returns to the water-collecting position or self-rights by letting go of the cable or by removing the pole from the hook, that is, the variable thickness and corresponding weight of the gutter along the axis, i. e. the center of gravity of the gutter, wants to return to its original position.

The rotor blades of a helicopter are balanced both in the chordal direction and in the spanwise direction in a static balancing assembly. The assembly includes a support surface on which there are four weighing scales. The scales are positioned in close proximity with the four corners of the rotor blade. The scales provide four cooperating pairs of blade spanwise and chordwise balancing reference data. The scales are operably connected to a microprocessor which is preprogrammed with desired balance data for the blades being tested. Deviations from the desired balance data detected by the scales and the microprocessor are corrected by selectively adding or subtracting weight on the blades at appropriate locations of the surfaces thereof.

A method for fabricating a helicopter blade subassembly includes the steps of providing a blade compaction apparatus having a lower assembly configured for mating with an upper assembly. The lower assembly includes a base having a contoured upper airfoil nest with at least two guide ramps and a plurality of leading-edge pusher cams disposed proximal thereto. The upper assembly includes a support structure supporting a flexible impervious membrane, wherein the flexible impervious membrane and the contoured upper airfoil nest define a molding cavity therebetween upon mating of the upper assembly to the lower assembly. The method further includes disposing the upper airfoil skin and the core in combination with the contoured upper airfoil nest, and then connecting a tip end support insert and a root end support insert in combination with the spar assembly, wherein each of the support inserts include guide members. The spar assembly is located in chordwise alignment in the contoured upper airfoil nest by driving the guide members into conics in the guide ramps and driving the spar assembly into a core conic with the leading-edge pusher cams. The lower airfoil skin is then disposed in combination with the core and the spar to form the helicopter blade subassembly, and then the upper assembly is mated to the lower assembly.

Apparatus and methods for fabricating a helicopter main rotor blade include a compaction fixture for assembling and compacting blade subassembly components and a sheath spreading/insertion apparatus for spreading and inserting a leading-edge sheath onto the blade subassembly during the compaction process. The compaction fixture includes a lower assembly having a contoured upper airfoil nest mounted in combination with a support structure and an upper assembly having a pressure bag affixed in sealed combination to a contoured backplate affixed in combination to a structural support truss. The contoured upper airfoil nest includes a plurality of tooling pins for locating an upper composite skin in aligned combination on the contoured upper airfoil nest and a plurality of pusher pins for chordwise alignment of a spar assembly in the contoured upper airfoil nest. Spar stanchions affixed to the support structure provide spanwise alignment of the spar assembly in the contoured upper airfoil nest. With the upper and lower assemblies in locked combination, the pressure bag is pressurized to compact the assembled blade subassembly components.
