Abstract: An aircraft wing configuration for a vertical or a short take-off and landing aircraft having a plurality of propeller-blown wings mounted at different longitudinal locations along a fuselage of the vertical take-off and landing aircraft, producing two or more lifting surfaces, fixed at a predetermined acute wing angle greater than 0° and substantially less than 90° relative to a horizontal plane, and having a plurality of flaps disposed behind the wings. The configuration has a plurality of propellers distributed in front of the plurality of wings producing two or more lifting surfaces and mounted such that the wings are externally blown by forced airstreams from the propellers. The propellers produce distributed thrust components, and the plurality of flaps are in the forced airstreams of the propellers when one or more of the flaps is in an extended position.

Abstract: A pair of bars form a vise, and are clamped together against a tool blade to be notched by a file. One clamp screw passing through the bars acts as a constant reference for one side of a tool blade, while a second clamp screw is repositioned in a clearance holes to accommodate various widths of blades. A top edge of the vise is used as a reference for blade extension, and a bottom edge is used to support the assembly on a bench top while in use.
