20100275684 | FLUID FLOW MONITORING - To provide an indication of whether airflow is separated, as opposed to other states of flow, over a surface, two or more adjacent sensors at a location on the surface each produce an analogue signal representative of airflow. The analogue signals are correlated with each other, and the degree of correlation indicates whether the airflow is in a separated state. The correlation may be carried out by comparing processed values of the analogue signals, and thresholding the comparison result. | 11-04-2010 |

20100170333 | FLUID FLOW MONITORING - In order to discriminate between laminar flow and turbulent flow states, and to provide an indication, e.g. to a pilot of an aircraft of air flow over an aircraft wing, a sensor mounted on the wing provides an analogue signal of airflow, and an intermittency value of the analogue signal is derived in analogue circuitry including an AC coupling of the signal to an integrator for integrating the signal for a preset time. The integrated value is compared with a threshold value to indicate whether the intermittency represents quiet laminar flow or noisy turbulent flow. | 07-08-2010 |

20080292888 | Microfabrication - A method of forming a surface of micrometer dimensions conforming to a desired contour for a MEMS device, the method comprising providing a crystalline silicon substrate with a recess in an upper surface, providing a thinner layer of crystalline silicon over the upper surface of the substrate, fusion bonding the layer to the substrate under vacuum conditions, and applying heat to the layer and applying atmospheric pressure on the layer, such as to plastically deform the diaphragm within the recess to the desired contour. The substrate may form the fixed electrode of an electrostatic MEMS actuator, operating on the zip principle. | 11-27-2008 |
20090050734 | FLOW CONTROL ACTUATORS - A flow control actuator | 02-26-2009 |
20090230499 | Sensor device - A sensor device for sensing air flow speed at the exterior of an aircraft, comprising a substrate having an upper side on which is mounted a diaphragm over an aperture or recess in the substrate, the diaphragm being thermally and electrically insulative, and mounting on its upper surface a heating element comprising a layer of resistive material, and wherein electrical connections to the heating element are buried in the diaphragm and/or the substrate, and provide electrical terminals at the lower side of the substrate. The heating element is exposed to the environment, but the remaining electrical parts of the device are not exposed. | 09-17-2009 |
20100126140 | MILLIMETRE-SCALE ENGINE - A millimetre-scale pulse jet engine comprises an engine body that defines a combustion chamber, a fuel, an air intake, and an exhaust. The fuel inlet is arranged to inject fuel directly into the combustion chamber. The air intake and the exhaust are in fluid communication with the combustion chamber, and the combustion chamber is configured such that air from the air intake and fuel from the fuel inlet cyclically combust in the combustion chamber to produce exhaust gases. | 05-27-2010 |
20110226675 | PARTICLE SEPARATORS - A particle separator stage in a particle separator includes an inflow passage of generally annular, axially facing form. In other embodiments, an asymmetric geometry is disclosed in which the major flow is taken from one side only. These features combine to allow compact, multi-stage separators to be produced. Also disclosed an arrangement in which the flow rate at a location within the separator stage is measured and used to control the flow rate there or elsewhere. | 09-22-2011 |

20110167788 | THRUST VECTORING APPARATUS FOR A JET ENGINE, CORRESPONDING JET ENGINE, THRUST VECTORING METHOD AND UPGRADING METHOD FOR A JET ENGINE - The thrust vectoring apparatus comprises: a housing defining a primary outlet for emitting the primary jet; Coanda surfaces extending from opposing regions of said housing, and radially spaced from the primary outlet such that a step is defined between each Coanda surface and the primary outlet; ducts leading from a fluid source to secondary outlets; and flow control means operable to control the mass flow through the secondary outlets. When the jet engine operates to exhaust a primary jet through the primary outlet, low pressure regions are formed in the vicinity of the steps. Each secondary outlet is located adjacent one of the Coanda surfaces so as to emit a secondary flow into a low pressure region. On activation of the secondary flow by the flow control means, the primary jet is entrained by the Coanda surface opposing the Coanda surface adjacent said the secondary outlet from which the secondary flow has been emitted. Method of vectoring the thrust or of upgrading existing jet engines with the thrust vectoring apparatus and jet engines comprising the thrust vectoring apparatus are disclosed | 07-14-2011 |
