A gearbox for driving a sprocket includes a gear train and an output shaft assembly positioned between the gear train and a power output end of the gearbox. The output shaft assembly includes, a first shaft segment extending to the power output a second shaft segment coupled to the gear train and a torsion spring interposed between the first shaft segment and the second shaft segment. Upon non-conjugate meshing of the sprocket, the torsion spring expands and contracts so that the angular velocity of the second shaft segment differs from the angular velocity of the first shaft segment.

An electric taxi system (ETS) for an aircraft may include an electric motor positioned on a landing gear assembly of the aircraft; and one or more selectively operable engaging members for selectively coupling the ETS with a wheel of the aircraft. The engaging members may be drivably coupled to the electric motor. The engaging members may each have a base member and a leading end. An axis of the base member and an axis of the leading end may be in straight-line alignment upon initial engagement of the engaging member with the wheel. The axes of the leading end and the base member may displaced from a straight-line alignment responsively to lateral forces exerted on the leading end resulting from deflections of the wheel during taxiing of the aircraft.

An aircraft landing gear wheel is disclosed. A main body includes a hub portion with a gear end and an attachment end. A driven gear portion includes a first annular rail and a second annular rail, the driven gear portion being integrally and drivingly connected with the hub portion at the gear end. Rollers are rotatingly connected between roller apertures of the first annular rail and the second annular rail. Bearings rotatingly support portions of the rollers within the roller apertures.

Compact exhaust mixer assemblies comprising a compact mixer and a trimmable open centerbody are provided. The trimmable center body allows for adjustments of the open centerbody after manufacturing and during production testing. The trimmable open centerbody may be used to compensate for production tolerances making it possible to obtain the desired core effective area for proper engine operation. The compact mixer may be either lobed or serrated. The compact exhaust mixer assemblies have a length of about half that of conventional exhaust mixer assemblies.

An apparatus and method for testing the flow distribution through a turbine engine fuel manifold and one or more nozzles connected to the manifold. A plurality of individual fluid measurement vessels, at least one for each of the nozzles being tested, collects test fluid pumped through the manifold and the connected nozzles. The level in each of the measurement vessels is periodically sampled during the test. The test fluid flow rate through each of the nozzles is periodically determined based on the periodically sampled levels.
