| Number | Title | Issue Date |
| 7413141 | Gas turbine engine fuel control system and regulating valves therefor A fuel control system for reheat burners of a gas turbine engine has a plurality of metering valves for respective burners, and throttle valves in series with the respective metering valves. A pressure regulating valve is provided for introducing pressurized fuel in... | 08/19/2008 |
| 6935813 | Control mechanism, an installation and a method for transporting bulk material, granular material or powdery material through a conveyor line A control mechanism (20; 70) and a method for use in an installation for transporting bulk material, granular material or powdery material through a conveyor line (1) with the aid of a pressurized gaseous medium. The control mechanism (20; 70) i... | 08/30/2005 |
| 4398388 | High bypass ratio supplemental fuel injection An afterburner on a turbofan or fan-jet engine contains a fuel system having a fuel control delivering fuel to a plurality of injection zones. As the power lever is advanced, for afterburner operation, fuel is delivered sequentially to the afterburner thr... | 08/16/1983 |
| 4244183 | Control means for an augmentor for a gas turbine engine This invention serves to improve augmentor effectiveness of a turbine fan engine that has a bypass airstream and a core stream by synthesizing signals indicative of both the airflow of the bypass stream and core stream and directly scheduling fuel/air rat... | 01/13/1981 |
| 4134259 | Fuel manifold prefill For improved thrust responsiveness and smooth transition of the various zones of an augmentor of an augmented jet engine powered aircraft, the time to prefill the fuel manifolds of the zones are calculated from preselected parameters so as to be on line u... | 01/16/1979 |
| 4128995 | Method and apparatus for stabilizing an augmenter system A turbine is stabilized in high speed, high altitude flight conditions by reducing the maximum augmenter fuel/air ratio in response to certain pressure and temperature conditions. Temperatures and pressures indicative of those at the combustor are sensed ... | 12/12/1978 |
| 4095420 | Augmentor outer segment lockout and fan upmatch A thrust augmented twin spool turbofan engine system to control instability at high altitude, low Mach number conditions wherein an engine electronic control monitors engine inlet temperature, engine burner pressure and Mach number, and inhibits fuel flow... | 06/20/1978 |
| 4027473 | Fuel distribution valve This invention relates to a fuel distribution valve for a turbine type power plane capable of supplying fuel to a set of primary nozzles and proportioning the flow to a set or sets of secondary nozzles upon initiation of a command signal which may be mani... | 06/07/1977 |
| 4027474 | Fuel prefill and distributor valve construction A fuel distributor valve for splitting and proportioning fuel feeding more than one set of fuel nozzles of a turbine type power plant is improved upon by adding thereto means to prefill the secondary nozzle and its attendant manifold and fuel passages imm... | 06/07/1977 |
| 3977187 | Device for detecting effective operation of the reheat system of a turbo-jet engine In order to detect effective operation of the reheat system of a turbo-jet ngine, a detection device is provided which is adapted to produce an output signal when such effective operation is sensed. The detection device includes means for sensing the press... | 08/31/1976 |
| 3937014 | Electric control circuit arrangements for gas turbine engines A control circuit arrangement for a gas turbine engine has first and second identical control circuits which are responsive to groups of input signals to provide nominally identical first and second output signals. It is arranged that input signals to the... | 02/10/1976 |
