Abstract
An airframe health monitoring system uses a controller to automatically determine a status of the airframe of an aircraft in real time, at power up and periodically during flight of the aircraft, based on the output of pressure sensors such as ribbon sensors and flex sensors mounted on the airframe arms and body. The controller can determine in real time whether the airframe has a fault or is damaged based on continuity measured in ribbon sensors located along the outside surfaces of the airframe. The controller can also determine a metric on the status of the airframe in real time based on arm impulses measured in flex sensors located along inside surfaces of arms of the airframe. This will lead to less expensive, more accurate, faster, automated detection of airframe faults, airframe damage and/or metrics on the health of the airframe.
