Simulation of Runway Irregularities in a Novel Test Rig for Fully Electrical Landing Gear Systems

The E-LISA research project, under way within the Clean Sky 2 framework, has objective of developing an innovative iron bird dedicated to executing tests on landing gear a small aircraft transport equipped with electro-mechanical and electrical brake. Such include simulation complete procedures different operating conditions such as runway friction, presence periodical defects along runway, variable weight, approach speed. To this end, requires novel solutions in both its architecture control scheme. This paper details solution that is being implemented enable execution gear, reproducing effects any type irregularity. First, rig presented detail, particular care toward hybrid position/force system manages operations. Then, model introduced verifying stability test capability reproduce articles produced leg irregularities. Simulations results are presented, highlighting proposed scheme providing preliminary assessment performances.
