Abstract: In order to significantly reduce the carbon produced in a combustor (10), and thus reduce or eliminate carbon buildup on combustor walls (14), a stored energy combustor (10) has a fuel discharge port (30) downstream of the combustion chamber (20). The downstream fuel discharge port (30) directs fuel into a secondary stored energy zone (24) downstream of a primary stored energy zone (22) comprised of an inlet end (16) and the combustion chamber (20) which receives an oxidant and a fuel through an upstream fuel discharge port (28) where the oxidant/fuel mixture is ignited to produce hot gases of combustion. The downstream fuel discharge port (30) is arranged to direct fuel in a manner forming a fuel film on the interior wall (14) in the secondary stored energy zone (24) such that the hot gases of combustion interact with the fuel film to cause fuel evaporation by establishing a stratified fuel annulus (54, 56).

Abstract: A servo controlled trolling motor steering system provides improved speed and steering control. The system includes apparatus for mounting the motor on a boat for rotation about an axis to effect steering of the boat. A foot pedal includes a base and a foot pad pivotally mounted to the base, the foot pad being pivotal by a user to command a desired steering direction. A membrane potentiometer senses rotational position of the motor to develop an electrical signal representative of the rotational position, the signal comprising a steering feedback signal. A second membrane potentiometer senses pivotal position of the foot pad relative to the base to develop an electrical signal representative of the pivotal position, the signal comprising a steering command signal.

Abstract: The expense of a cover (80) for non-uniform structure (38) on or adjacent a surface (90) of a rear turbine shroud 34 facing a cooling passage defined by the rear engine shroud (34) and a wall (62) of a combustor (50) in a gas turbine engine can be avoided by providing a connecting wall (100) that is smoothly curved between the radially inner wall (58) and a conical wall (62) of the combustor (50). The resulting cooling air stream will attach itself to the walls (100) and (62) by reason of the Coanda effect, rendering the presence of non-uniform structure (38) on the surface (90) unimportant.
