SENSING SYSTEMS |
摘要 |
This invention relates to volcanic ash sensing techniques for aircraft, and to related sensing apparatus and methods. We thus describe a volcanic ash sensor for an aircraft, the sensor comprising: an electrically conducting ash charge collection device; an electrically insulating support for mounting said collection device in an air duct; and a charge measurement system having an input electrically coupled to said ash charge collection device; wherein said electrically conducting ash charge collection device is configured such that an air flow over said ash charge collection device is a turbulent flow; and wherein said charge measurement system is configured to determine a level of charge in said ash charge collection device to determine the presence of volcanic ash in said air flow. |
