Abstract: A wall surface pressure measurement structure measures a wall surface pressure in a duct. Measurement holes are formed in different positions in a circumferential direction on an inspection surface of a wall surface of the duct. The inspection surface is orthogonal to an extending direction of the duct. A pressure chamber communicating with the measurement holes is provided on an outer peripheral side of the duct. The pressure chamber is coupled to a pressure gauge via a pressure pipe.

Abstract: It is intended to recognize the state of charge or depth of discharge of the battery more accurately than conventional technologies and to recognize health of a battery appropriately. Complex impedance between positive and negative electrodes of the battery is determined at a plurality of frequencies, and the state of charge or depth of discharge of the battery is estimated by comparing frequency dependency of Warburg impedance of the determined complex impedances with frequency dependency of Warburg impedance corresponding to a known state of charge or depth of discharge of the battery. Similarly, complex impedance is determined, and the health of the battery is evaluated by using the real part of the complex impedance at a point where the imaginary part of the complex impedance is zero on a line obtained by extending a part, which indicates frequency dependency of Warburg impedance, of a complex impedance characteristic curve representing a correlation relationship between the real and imaginary parts of the determined complex impedance.

Abstract: A motorized aircraft is controlled by a drive control means that rotationally drives a propulsion system propeller. The propulsion system propeller is driven by a plurality of electric motors. A comparison detection unit compares estimated propeller torque and estimated motor torque with each other and detects an abnormal state of an electric motor on the basis of the fact that a difference between the propeller torque and a multiple of the motor torque is above a predetermined value.
