Most modern AFVs are superficially similar in design to their World War II counterparts, with significantly better armour, weapons, engines and suspension-however with an increase in the capacity of transport aircraft allowing AFVs to be practically transported by air, many armies are replacing some or all of their traditional heavy vehicles with lighter airmobile versions, often with wheels instead of tracks.

Most liquid-phase engines have focused on rotating the fuel / fluid mixture at very high speeds, forcing the fuel to the outside due to centripetal force ( uranium is heavier than hydrogen ).

Most designs are rocket engines where the energy is provided by the beam, and is used to superheat propellant that then provides propulsion, although some obtain propulsion directly from light pressure acting on a light sail structure, and at low altitude heating air gives extra thrust.

Most Red Army tanks from this period in time had diesel engines.

Most modern search engines have the ability to analyze a page for keyword stuffing and determine whether the frequency is consistent with other sites created specifically to attract search engine traffic.

Most aircraft installations are double-ended, because the ejection of empty cartridges can cause a foreign-object damage ( FOD ) hazard for jet engines and because the retention of spent cases assists in maintaining the center of gravity of the aircraft.

Most modern jet planes use turbofan jet engines which balance the advantages of a propeller, while retaining the exhaust speed and power of a jet.

Most production carbureted ( as opposed to fuel-injected ) engines have a single carburetor and a matching intake manifold that divides and transports the air fuel mixture to the intake valves, though some engines ( like motorcycle engines ) use multiple carburetors on split heads.

It ranks highly in terms of liveability, being listed in the Top 10 of The Economist's World's Most Liveable Cities index in 2010 and being ranked the most liveable city in Australia by the Property Council of Australia in 2011 and again in 2012.
