A recuperator for a gas turbine engine comprises a plurality of cells that are orientated in an annular array and attached to one another at only the radially inner edges thereof. Each cell comprises a high pressure plate having spaced integral ribs thereon defining a plurality of low temperature compressed air passages and a low pressure plate having a plurality of spaced ribs defining a plurality of high temperature exhaust gas passages.

Gas turbine engine recuperator

A compliant hydrodynamic gas bearing comprises a nonlinear spring arrangement for supporting a plurality of tilting arcuate pads which hydrodynamically carry radial journal loads. The nonlinear spring support arrangement enables the bearing to provide increasing load-deflection capacity under extreme loads to limit deflection to a predetermined clearance. The spring arrangement provides nonlinear load-deflection capabilities while operating with a designed constant bending stress.

Nonlinear spring supported hydrodynamic bearing

A propulsion system comprises a gas turbine engine having sructurally integrated support systems that maximize structural efficiency and minimize cost.

Integrated propulsion system

An improved blade folding system for a propfan propulsion system comprises a fan blade journaled for rotation from a folded position substantially tangentially related to the housing of an engine to a radially extending run condition.

Foldable propulsion system

A fuel slinger for a gas turbine is provided with a hydraulic fuel trap within the U-shaped cross section thereof to inject fuel metered by a low pressure fuel system into a combustion chamber at relatively higher pressure.
