US Patent:

Filed:

Dec 12, 2008

Appl. No.:

12/333770

Inventors:

Brian E. Tews - Melbourne FL, US
Christian O. Rodriguez - Palm Bay FL, US

Assignee:

Mainstream Engineering Corp. - Rockledge FL

International Classification:

F01D 1/00
F01D 1/02

US Classification:

415220, 415207, 4152112

Abstract:

A method for increasing the total-to-static pressure ratio across a Ram Air Turbine (RAT) has designed and experimentally tested. The invention develops a localized accelerated flow of free-stream air near the discharge of the turbine rotor exhaust. This localized accelerated flow decreases the static pressure at the exit of the turbine and allows for additional power generation for a given free-stream flight condition. Full-scale wind tunnel experimenting testing shows that creating this low static pressure region behind the turbine resulted in significant increases in turbine output power when compared to a turbine that is not subjected to this invention. The invention showed the ability to increase the total-to-static pressure ratio across the turbine.

International Classification:

F03D 11/00

US Classification:

4152112

Abstract:

The total-to-static pressure ratio is increased across a Ram Air Turbine (RAT) by developing a localized accelerated flow of free-stream air near the discharge of the turbine rotor exhaust. This localized accelerated flow decreases the static pressure at the exit of the turbine and allows for additional power generation for a given free-stream flight condition. Lobe mixers in various locations improves mixing between the accelerated flow and the turbine exhaust flow, and the combined exhaust flow and the free-stream air surrounding the aerodynamic body.

Abstract:

A heat exchanger includes at least one conduit configured to carry a working fluid. The heat exchanger also includes a plurality of chambers in proximity to the at least one conduit, each chamber configured to contain a phase change material (PCM) that expands upon freezing. The at least one conduit and the plurality of chambers are thermally coupled for transfer of thermal energy between the working fluid and the PCM in each chamber. One wall of each chamber is formed of a compliant layer configured to deform to increase a volume of the chamber as the PCM expands upon freezing.
