Some embodiments are directed to an electromagnetic interference (EMI) indicator includes an ultra-wideband detector, preferably having a bandwidth of at least 30 MHz to 6 GHz. At least one antenna is provided for receiving EMI. Each antenna has receiver protection, a logarithmic receiver to convert the EMI signal into a direct voltage proportional to the magnitude of the EMI signal, a peak/average detector, and a controller connected to the output of the receiver for generating a signal when the direct voltage developed in the detector exceeds a pre-set threshold voltage using, for example, a carefully defined algorithm. The peak/average detector and controller are connectable to an indicator, which is activateable by the controller, which stores EMI event data in a non-volatile memory store.

An oil and gas well shaped charge perforator capable of providing an exothermic reaction after detonation is provided, comprising a housing (2), a high explosive (3), and a reactive liner (6) where the high explosive (3) is positioned between the reactive liner (6) and the housing (2). The reactive liner (6) is produced from a composition which is capable of sustaining an exothermic reaction during the formation of the cutting jet. The composition may be selected from any known formulation which is suitable for use in an oil and gas well perforator, typically the composition will comprise at least two metals such as to form an inter-metallic as classified by Hume-Rothery electron compounds and at least one further metal, which is not capable of an exothermic reaction with the reactive composition which is present in an amount greater than 10% w/w of the liner (6).

A sheet of thermally reflective material (1) has a surface texture comprising a plurality of reflecting elements (2), wherein each element has a first face (4) which is substantially reflective at thermal infrared wavelengths and wherein the respective first facets (4) form an angle with the plane of the sheet (A-B)( 0 < < 90). Preferably, the first facets (4) are aligned such that, in use, thermal radiation is reflected from a common direction. By orienting the sheet of thermally reflective material to reflect cold regions of the sky, a marking material exhibiting a cold spot in a thermal imager can be provided.

A fibre reinforced polymer (FRP) composite structure incorporates a woven preform containing tows of carbon or other advanced fibres (1,3) and wires (2,4) of shape memory alloy (SMA). The SMA wires are capable of absorbing much larger amounts of strain energy than the conventional components of FRP composites and hence enhance the impact resistance of the structure. The woven form incorporates the SMA into the structure in an optimum manner in terms of handling and performance.

Patent
QinetiQ | Date: 2017-05-17

A method for mitigating interference in a receiver, where the received signal is transmitted in a fashion having equivalent information content in at least two distinct bands (30, 31) is disclosed. The method compares mean power per unit bandwidth in suitably normalised sidebands and sets a rejection threshold (32, 33, 34) based upon the measured levels. Bands above the threshold may be rejected from further processing. The bands may comprise sidebands produced by a modulation process that inherently produces sidebands having the same informational content. The threshold may be set relative to the band having the lowest mean power per unit bandwidth, or may be set according to some other function of the bands. The invention extends to a signal processor in a receiver, and to a receiver itself. The primary focus of the application is toward the Galileo Public Regulated Service (PRS) Satellite navigation signal. This is a Binary Offset Carrier (BOC) signal that is designed to put most of its transmission energy into two sidebands symmetrically about a centre frequency. Each sideband contains, at the position of transmission, the same information content.

The consortium proposes an innovative activity to develop, build and test to TRL5 the first European Plug and Play Gridded Ion Engine Standardised Electric Propulsion Platform (GIESEPP) to operate Airbus Safran Launchers and QinetiQ Space ion engines. These are the only European ion engines in the 200-700W (LEO) and 5kW (GEO) domains that are space-proven, and the consortiums intention will be to improve European competitiveness and to maintain and secure the European non-dependence in this field. The project will design and develop a standardised electric propulsion platform for 200-700W and 5kW applications, which has the capability to run either Airbus Safran Launchers or QinetiQ thrusters. In addition, the 5kW electric propulsion system will be designed to allow clustering for 20kW EPS for space transportation, exploration and interplanetary missions. In order to cope with challenging mission scenarios, Dual Mode functionality of the thrusters will be realised. This ensures that the beneficial high Isp characteristics of Gridded Ion Engines are maintained, whilst also offering a competitive higher thrust mode. The GIESEPP systems will not be limited to xenon as an operating medium; assessments will be performed to ensure functionality with alternative propellants. The approach to system standardisation and the resulting solutions will provide highly cost competitive and innovative EPS for current and future satellite markets, whilst meeting the cost efficiency requirements. The proposal will describe the roadmap to higher TRL by 2023-2024, providing a cost competitive EPS. Finally, the proposal will address efficient exploitation of the results, demonstrating how the activity will positively increase the impact and prospects for European Ion Engines and the European Electric Propulsion System community.
