drift excursion (plural drift excursions)

1. The movement of something (such as a vehicle, structure, or charged particles) from its intended course or position due to outside forces.
   • 1966, Carl A. Wagner, The Earth's Longitude Gravity Field as Sensed by the Drift of Three, page 89:

     A very close approximation to the geographic drift excursion in a resonant gravity field of a 24-hour satellite follows the differential equation of motion, Equation 2, (see also Reference 2) and is, evidently, given by an elliptical integral such as that developed in Appendix E of Reference 3.

   • 2013, Roscoe B White, Theory Of Toroidally Confined Plasmas, page 418:

     A collision changes the detailed nature of the particle orbit in a time which is very short compared to the time required to traverse magnetic field scale lengths, thus producing a step across flux surfaces the size of the orbit drift excursion away from the flux surface .

   • 2024, S. Lalit Sagar, Dipti Ranjan Sahoo, T. P. Anand, Vasant A. Matsagar, “Development of a Quasi-Static Bidirectional Loading Protocol for the Seismic Evaluation of Hybrid RC-SCC Beam-Column Joints”, in Federico M. Mazzolani, editor, Proceedings of the 11th International Conference on Behaviour of Steel Structures in Seismic Areas:

     The bidirectional drift excursion for the beam-column joint is applied in the anticlockwise direction as per the numbering sequence illustrated in Figs. 8a and 8b.
