Abstract: An aircraft comprises a fuselage, one or more support structures connected to the fuselage, one or more engines or motors disposed within or attached to the one or more support structures or the fuselage, and a distributed propulsion system. The distributed propulsion system comprising two or more propellers symmetrically distributed in an array along the one or more support structures with respect to a center of gravity of the aircraft and operably connected to the one or more engines or motors, wherein each propeller has a rotation direction within a tilted plane of rotation, and a summation of horizontal force vectors created by the tilted plane of rotation of all the propellers is substantially zero when all the propellers are creating a substantially equal thrust magnitude. Movement of the aircraft is controlled by selectively increasing or decreasing a thrust of at least one of the two or more propellers.

Abstract: A self-retaining wear-pad leveler has a first plate having arms on opposing sides and forming an aperture through the first plate. A rear section is coupled to a rear portion of the first plate and has tabs extending from opposing sides of the rear section. The arms are configured for being retained about a ball of a spherical bearing assembly, and the tabs are configured to cause rotation of the leveler about the bearing when engaged by a component coupled to and rotating about the bearing.
