Using a downhole motor with bent housing most effectively requires determination of its deflecting performance and designing the bottom hole assembly according to the expected deflection rate.

Abstract: The flight pose of an aircraft is affected seriously by the stress-deflection angles of aileron and tail fin. Traditional manual measurement suffers from ...

Abstract: During the flight control system testing (FCST), it is crucial to accurately measure the deflection angles of flight control surfaces to determine whether they respond precisely to commands.
