The invention relates to a thrust reverser for a jet engine of an aircraft, which comprises two symmetrical doors pivotally mounted about an axis which is transverse and substantially diametrical to the jet of said engine and which is disposed downstream of the jet exhaust pipe thereof, the doors each being pivoted due to two diametrically opposite hinges and occupying a folded or stowed position in which they form part of the fairing of the engine or fuselage of the aircraft, or an unfolded or ...

A thrust augmentor for a turbofan, gas turbine engine is disclosed. Techniques for mixing and burning dissimilar density gases in a thrust augmentor are developed. In accordance with one specific teaching the flame front in a swirl augmentor is stabilized by a continuously operative pilot burner. The pilot burner is positioned in the radially outward portion of the augmentor. The pilot burner employs fuel premixing techniques and is adapted to operate at low inlet pressure levels.

A gas turbine engine having variable geometry flow controllers therein for controlling mass flow in accordance with engine operation includes a rotor with a wide variation in thrust forces thereon during different phases of engine operation countered by a variable axial load integrating device having a rotating hydraulic thrust compensating piston mounted forwardly of the rotor in association with a rotor thrust bearing and further including means for generating a centrifugal head in accordance ...

An improved thrust bearing has a shaft with a runner coupled to the end of the shaft. The runner has a first sealing face that extends radially from the shaft. A bearing has a fluid passage for supplying fluid to a fluid reservoir. The fluid reservoir may be in the runner or in the bearing. The bearing has a second sealing face opposite the first sealing face of the runner. The first sealing face has a recess that is in fluid communication with the fluid reservoir. Fluid from the fluid reservoir...

A coupling device is provided with two flanges and a resilient annular member disposed between facing surfaces of the flanges. The resilient annular member is provided with a central opening through which a metallic spring is disposed to exert a resistive force against compression of the resilient annular member between the two flanges. The device is particularly well suited for use in a marine propulsion system because of the propulsive force exerted on the shaft system by the propeller. In one...

A thrust bearing for a rotating member that is subject to axial forces causing movement in an axial direction of a rotating member. A sealing surface is positioned on at least a portion of the rotating member. A bearing is positioned adjacent the rotating member. A sealing face is positioned on the bearing. The sealing face is disposed to be in opposed relationship with the sealing surface on the rotating member. A bearing space is located between the sealing face and the sealing surface. A flui...

A thrust bearing includes a flange formed on the outside of only a first bearing washer, a second bearing washer formed into a simple flat plate, a notch having a rectangular cross-section formed on the outside of the second bearing washer, and a leading edge of the flange bent so that it is inserted into the notch.

A self-equalizing thrust bearing has shoes mounted atop axially movable support pins, and equalizing pins rotatable about radial axes are interposed between and engage the support pins to provide for self-equalizing and to hold the support pins in the retaining ring. The equalizing pins are provided with oil passages for improved lubrication; and there are retainer clips to hold the shoes on the support pins but which do not affect operational movement of the shoes.

This invention is a thrust bearing comprising a circumferential ring of pivotally mounted thrust pads and in order to make a much more simple bearing than the previously known kind in which each pad is supported from a thrust ring mounted within the housing, in the present invention each pad is supported on its individual thrust pillar which is itself supported against a wall of the bearing housing. There is a ring for locating the pillars circumferentially but that does not play any part in car...

Thrust bearings need to be under axial load to prevent skidding of the balls in the races. In a gas turbine engine, the thrust bearings between relatively rotatable shafts can experience zero load as engine conditions vary. A permanent load is therefore applied by causing an extension 38 of cage 22 to run in an oil reservoir 30. The resultant drag applies a torque to the cage and affects its speed of rotation relative to that of the shafts 10 and 14.
