Mathematical Simulation and Experimental Investigation of a Contactless Measuring Section in the Problem on High-Velocity Ballistic Flights

  • Published:
Journal of Engineering Physics and Thermophysics Aims and scope

A method and system for contactless measurement of the velocity of flight of a thrown body over a measuring base in an air atmosphere and for the actuation of a recording apparatus by the signal formed as a result of the passage of the body through a measuring section are presented. The method proposed is based on the formation of normalized pulses of positive polarity for the synchronization of the activation of a recording apparatus by a definite coordinate of a body thrown. Results of calculation and experimental investigations of variable reluctance pickups in tests of high-velocity ballistic flights are presented. Relations allowing one to estimate the dependence of the magnetic induction in the core of a variable reluctance pickup on the value of the air gap between a magnet and the pickup are presented.
