  • Turbine exhaust diffuser flow path with region of reduced total flow area
    Patent number: 8337153
    Abstract: An exhaust diffuser system and method for a turbine engine includes an inner boundary and an outer boundary with a flow path defined therebetween. The inner boundary is defined at least in part by a hub that has an upstream end and a downstream end. The outer boundary has a region in which the outer boundary extends radially inward toward the hub. The region can begin at a point that is substantially aligned with the downstream end of the hub or, alternatively, at a point that is proximately upstream of the downstream end of the hub. The region directs at least a portion of an exhaust flow in the diffuser toward the hub. As a result, the exhaust diffuser system and method can achieve the performance of a long hub system while enjoying the costs of a short hub system.

  • TURBINE WITH UNEVENLY LOADED ROTOR BLADES
    Publication number: 20120301283
    Abstract: An unevenly loaded turbine rotor blade is disclosed herein, the blade including a power-extracting region adapted for radially-varied (relative to the axis of rotation) power extraction per mass flow rate. The pitch and/or shape of the airfoil at a first radial position may be configured, so that power extraction per mass flow rate at the first radial position is different than power extraction per mass flow rate at a second radial position. Thus, the power-extracting region may be advantageously configured to take advantage of a non-uniform flow profile across a rotor plane such as may be induced using a shrouded turbine.

  • Apparatus to protect a radon fan from mechanical failure due to damage from falling objects from within the radon mitigation system
    Publication number: 20120294708
    Abstract: This apparatus protects a radon fan from damage due to falling water, ice, critters and debris and is installed above the radon fan and protects the fan in several ways. It is installed just above the radon fan, thus taking advantage of warm “Earth Temperature” air to reduce ice build-up. Its screen replaces the critter screen often installed at the top of the exhaust pipe where ice is formed. The screen additionally prevents ice and debris from falling into the fan. The water bypass catches back-flowing water and directs it around the fan. The access port serves as an opening for testing, observations and cleaning of any debris that is collected by the screen and the access port is sealed with a removable plug. This apparatus protects and extends the life of a radon fan and is made part of the radon mitigation system.
