The invention relates to a launched aerial surveillance vehicle, more specifically to a grenade or under-slung grenade launcher (UGL) aerial surveillance vehicle, a surveillance system and methods of providing rapid aerial surveillance. The vehicle once deployed is capable of autonomous flight paths, with basic inputs to change the circular flight paths, so as to build up surveillance for an area of interest. The vehicle comprises at least one optical sensor, which may be IR or visible range, to survey the area of interest, and feed the images back to at least one remote user.

Surveillance system

A temperature monitoring arrangement for an electro-thermal ice protection system is provided for a slat of an aircraft wing, incorporating heater mats of composite material, wherein, in order to avoid or at least substantially reduce some of the problems associated with use of discrete temperature sensing elements, one or more optical fiber temperature sensors are embedded within the heater mats for sensing an overheating condition of each mat. Advantageously, a control system is used to monitor the temperature of the mats, and adjusts power supplied, or switches off power, in response to detection of an overheating condition.

Temperature monitoring

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.
