Two test launches were recovered by the Allies: the Bäckebo rocket which landed in Sweden on 13 June 1944 and one recovered by the Polish resistance on 30 May 1944 from Blizna and transported to the UK during Operation Most III.

Most chemical-reaction monopropellant rocket systems consist of a fuel tank, usually a titanium or aluminium sphere, with an ethylene-propylene rubber container or a surface tension propellant management device filled with the fuel.

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 proposed antimatter rocket designs require a large amount of antimatter ( around 10 grams to reach Mars in one month ).

Most dismiss Harriman's plans as foolhardy: Nuclear rocket fuel is scarce as the space station that produces it blew up, also destroying the only existing spaceship.

Most significantly, the LACE system is far heavier than a pure rocket engine having the same thrust ( air-breathing engines of almost all types have relatively poor thrust-to-weight ratios compared to rockets ), and the performance of launch vehicles of all types is particularly affected by increases in vehicle dry mass ( such as engines ) that must be carried all the way to orbit, as opposed to oxidizer mass that would be burnt off over the course of the flight.

Most spacecraft have some variety of rocket engine, and thus most research efforts focus on some variety of rocket propulsion, such as chemical, nuclear or electric.

Most of the Osenberg List engineers worked at the Baltic coast German Army Research Center Peenemünde, developing the V-2 rocket ; after capturing them, the Allies initially housed them and their families in Landshut, Bavaria, in southern Germany.

Most rocket engines are internal combustion engines, although non-combusting forms also exist.

Most of Clem's adventures begin with a classic opener mocking adventure comics and have an improbable mission issued by a mysterious " Chief ", only to collapse miserably because of some trivial impediment such as the neighbour using Clem's rocket to anchor her laundry line.

Most notable of the mercenaries was Swedish Count Carl Gustav von Rosen who led air attacks with five Malmö MFI-9 MiniCOIN small piston-engined aircraft, armed with rocket pods and machine guns.

Most of the rocket's power came from a clustered lower stage consisting of tanks taken from older rocket designs and strapped together to make a single large booster, leading critics to jokingly refer to it as " Cluster's Last Stand ".

Most often this involves the Autobots traveling to a location in the rocket, made only of Omega Supreme's arms, the rocket will then split in two and the rest of Omega Supreme's body seems to magically materialize out of the ground.

Most grappling hooks are thrown by hand, but some used in rescue work are propelled by compressed air ( e. g., the Plumett AL-52 ), mortar or a rocket.

In late July 1944, the Polish resistance ( Home Army and V1 and V2 ) secretly transported parts of the rocket out of Poland in Operation Most III ( Bridge III ), for analysis by British intelligence.

In late July 1944, the Polish resistance ( Home Army and V1 and V2 ) secretly transported parts of the rocket out of Poland in Operation Most III ( Bridge III ), for analysis by British intelligence.

Most players fix this by hyper jumping and shooting the rocket right on the heli for an instant kill.

Most of the weapons from the previous games returned, such as the rocket launcher, grenade launcher, 12-gauge double-barrel sawed-off shotgun and a sniper rifle.

Operation Most III ( Bridge III ) secretly transported parts of the rocket out of Poland for analysis by British intelligence.

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 modern high speed production engines are classified as " over square " or short-stroke, wherein the stroke is less than the diameter of the cylinder bore.

Most electric generation is driven by heat engines.

Most devices used in the industrial revolution were referred to as engines, and this is where the steam engine gained its name.

Most new engines rely on electrical and electronic engine control units ( ECU ) that also adjust the combustion process to increase efficiency and reduce emissions.

Most truck and automotive diesel engines use a cycle reminiscent of a four-stroke cycle, but with a compression heating ignition system, rather than needing a separate ignition system.

Most steel engines have a thermodynamic limit of 37 %.

Most engines today use Schnuerle porting instead.

Most steam-driven applications use steam turbines, which are more efficient than piston engines.

Most rotary engines were arranged with the cylinders pointing outwards from a single crankshaft, in the same general form as a radial, but there were also rotary boxer engines and even one-cylinder rotaries.

Most mobile steam engines and some smaller stationary engines discard the low-pressure steam instead of condensing it for reuse.

Most small trucks such as sport utility vehicles ( SUVs ) or pickups, and even light medium-duty trucks in North America and Russia will use petrol engines ( gasoline engines ), but many diesel engined models are now being produced.

Most V8 engines share a common crankpin between opposite cylinders in each bank, and a 90 ° V8 crankshaft has just four pins shared by eight cylinders, with two pistons per crankpin, allowing a cylinder to fire every 90 ° to achieve smooth operation.

Most are Mazda 12A and 13B automobile engines, converted to aviation use.

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 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.
