23 Jul 1969TL;DR: A TURBO-FAN POWER PLANT is described in this article, in which two independent fans in the audience are driven by a gas generator and a free turbine.
Abstract: A TURBO-FAN POWER PLANT IS DISCLOSED IN WHICH THEY ARE TWO INDEPENDENT FANS IN THE FAN DUCT RESPECTIVELY DRIVEN BY A GAS GENERATOR AND AN INDEPENDENT FREE TURBINE. THE GAS GENERATOR INCLUDES IN AXIAL FLOW SERIES LOW, INTERMEDATE AND HIGH PRESSURE COMPRESSOR RESPECTIVELY DRIVINGLY INTERCONNECTED WITH HIGH, INTERMEDIATE AND LOW PRESSURE TURBINES, THE INTERMEDIATE PRESSURE TURBINE BEING DRIVING- LY CONNECTED TO THE UPSTREAM OR FRONT OF THE TWO FAN THE DRIVE ARRANGEMENT OF THE FANS AND THEIR AXIAL SPACING ENABLES THEM TO ROTATE AT RELATIVELY LOW SPEEDS AND SUB STANTALLY WITHOUT ANY WAKE INTERACTION THEREBETWEEN , WHEREBY THE OVERALL NOISE OF THE POWER PLANT IS REDUCED.

TL;DR: In this article, a turbine engine accessory power unit has a compressor bleed air control system in which a surge bleed valve is proportionally and integrally controlled to maintain a constant minimum compressor bleed flow rate slightly above the compressor's surge flow rate.
Abstract: A turbine engine accessory power unit has a compressor bleed air control system in which a surge bleed valve is proportionally and integrally controlled to maintain a constant minimum compressor bleed flow rate slightly above the compressor's surge flow rate. The system control parameter is automatically reset as a function of the position of the compressor's adjustable inlet guide vanes to assure optimum control system performance throughout the air delivery range of the compressor.

24 Sep 1982TL;DR: In this article, a long lifetime Stirling cycle cryogenic cooling system for space applications is described, where a compressor section (10) centrally aligned end to end with an expansion section (12) and respectively including a reciprocating compressor piston (14) and displacer (16) radially suspended in interconnecting cylindrical housings (18, 20) by active magnetic bearings (26, 28, 30, 32) and having adjacent reduced clearance regions (82, 84, 108) so as to be in non-contacting relationship therewith and wherein one or
Abstract: A long lifetime Stirling cycle cryogenic cooler particularly adapted for space applications comprised of a compressor section (10) centrally aligned end to end with an expansion section (12) and respectively including a reciprocating compressor piston (14) and displacer (16) radially suspended in interconnecting cylindrical housings (18, 20) by active magnetic bearings (26, 28, 30, 32) and having adjacent reduced clearance regions (82, 84, 108) so as to be in non-contacting relationship therewith and wherein one or more of these regions operate as clearance seals. The piston (14) and displacer (16) are reciprocated in their housings (18, 20) by linear drive motors (48, 52) to vary the volume of respectively adjacent compression and expansion spaces (44, 46) which contain a gaseous working fluid and a thermal regenerator (95) to effect Stirling cycle cryogenic cooling. Electrical circuit means (140, 142) are additionally included for energizing the magnetic bearings (26, 28, 30, 32) and for controlling the stroke amplitudes and relative phase angle between the compressor piston (14) and displacer (16) during the cooling cycle.
