Michelin NZG from Concorde’s main landing gear

Concorde’s main landing gear comprises of two sets of four-wheel bogies. The main landing gear was designed by Messier-Dowty and has to shorten during the retraction process, as it would otherwise not be able to fit into the bays in the wing roots after take-off. It is also fitted with a spray guard to prevent water from wet runways being flung-up and sucked into the engine air intakes and also fitted with Oleo-pneumatic shock-absorbers.
