Rolls-Royce's flight test centre closed in 1971, but engines were still tested there until late 2008.

Although NERVA engines were built and tested as much as possible with flight-certified components and the engine was deemed ready for integration into a spacecraft, much of the U. S. space program was cancelled by the Nixon Administration before a manned visit to Mars could take place.

Although Los Alamos tested several KIWI and Phoebus engines during the 1960s, testing of NASA's NERVA NRX / EST ( Engine System Test ) contractor engine didn't begin until February 1966.

On September 2, the engines of Soyuz 29 were tested, 25 experiment containers with 100 experimental results were transferred, along with exposed film, and seat liners and centering weights were exchanged.

Entire engines could be built and tested at their factory before delivery.

Cadillac and Holden both tested variations of these engines in US and Australia.

During WWII, the Norden bombsight was built at the Rome site, and large airplane engines were rebuilt and tested.

The initial development engines were assembled at the nearby Santa Susana Field Laboratory where the Saturn V F-1 engines were developed and tested for the Apollo missions to the Moon.

She cut the engines and slowly the cruiser swung around on the end of its lines until its bow was pointing into the wind and the cockpit faced toward the shore.

This change was pushed forward by the development of heavier naval guns ( the ironclads of the 1880s carried some of the heaviest guns ever mounted at sea ), more sophisticated steam engines, and advances in metallurgy which made steel shipbuilding possible.

By bringing engine production back to within the company, the promise was that Aston Martin would be able to produce small runs of higher performance variants engines.

Colonel Kari Renko, an engineer at the Finnish Air Force, was quoted by Helsingin Sanomat as saying about this failure, " The problem involves the rocket engines which have been in use for decades " and that Finland first was told of the problems by the Americans about two years ago.

In the meantime, during the rule of Todor Zhivkov, a significant military industrial complex was established, capable of producing armored vehicles, self-proppelled artillery, small arms and ammunition, as well as aircraft engines and spare parts.

STS-51-F's first launch attempt on 12 July 1985 was halted with the countdown at T-3 seconds after main engine ignition, when a malfunction of the number two Space Shuttle Main Engine ( SSME ) coolant valve caused the shutdown of all three main engines.

" The relative status of various humans, some of whom had modern advanced technologies that included engines and telegraphs, while others lacked anything but face-to-face communication techniques and still lived a Paleolithic lifestyle, was of interest to the first generation of cultural anthropologists.

In an early " good-will " gesture that was later heavily criticised, the Attlee government allowed the Soviets access, under the terms of a 1946 UK-USSR Trade Agreement, to several Rolls-Royce Nene jet engines.

Although, in these early years, engines came in a number of configurations, typically Q < sub > H </ sub > was supplied by a boiler, wherein water was boiled over a furnace ; Q < sub > C </ sub > was typically a stream of cold flowing water in the form of a condenser located on a separate part of the engine.

This was a factor in the rise of V8 engines, with their shorter crankshafts, in preference to straight-8 engines.

The steam clipper was developed around this time, and had auxiliary steam engines which could be used in the absence of wind.

Before its merger with HP, it also sponsored the Williams Formula One team when it was still powered by BMW engines.

Inspired by Babbage's difference engine plans, Per Georg Scheutz built several difference engines from 1855 onwards, one of which was sold to the British government in 1859.

Human power was focused by the use of simple engines, such as the capstan, windlass or treadmill, and with ropes, pulleys, and block and tackle arrangements ; this power was transmitted usually with the forces multiplied and the speed reduced.
