Two kinds of dampers were developed and built: frictional and semiactive.
In this clearly-written text for practitioners, researchers and design engineers as well as postgraduate students, the authors present the newest information into semiactive control systems, which provide significant reductions comparable with active devices but are stable and have reduced power requirements.
Digital semiactive laser technology provides precision accuracy at low cost for 2.
The 6 kg, 558mm-long bomb fitted with a semiactive laser guidance system receives its target grids through the launch system.
8 kilos and with a calibre of 178 mm, the semiactive laser-guided Mokopa is little else than the South African equivalent of the Hellfire missile originally designed by Kentron, now Denel Dynamics, for use by the RooivaLk ground and armour attack helicopter.
