Lubricants at Low Temperatures - dtic.m

Lubricants represent the single most critical problem encountered by vehicles in cold regions. A vehicle lubricated for use in temperature regions will simply not operate in an extremely cold environment. A chunk of heavy gear oil can be used to pound nails at -40C. Thus it is of the utmost importance to ensure that all lubricants used in the vehicle be chosen with low-temperature operation in ...

Surrogate fuels and combustion characteristics of liquid .

Here, at high temperatures, we should note that the variability among real fuels in terms of high-temperature combustion behaviors is relatively modest. But, much larger and more poorly understood (and even identified) variabilities exist in the low-temperature reactivity, NTC, and hot ignition transition regimes (I–III in Figs. 5 and 6).

Reduced noise pol lution is also desirable near urban areas, lessening demon strable negative effects on human health. Further cost reductions may manifest in the ves sel maintenance budget. Shaft alignment, lubricants, and replacement parts are major costs on vessels equipped with reciprocating engines.

Amsoil dispels the One Arm Bandit test. - Bob Is The Oil G

Yeah, I posted that back in the day... laughable that thy dispelled the one armed bandit test in a period where they were advocating and justifying the 4 ball as appropriate for engine oils.

Federal Register Vol. 82, No.

AD 2014-05-25 required inspections of the low-pressure turbine (LPT) exhaust case and support assembly or tail bearing housing (TBH) to detect cracks or damage. This AD modifies the inspection schedule for the affected engines and adds an optional terminating action.

DTIC ADA206053: Field Evaluation of All-Season Tactical .

During the test, vehicles accumulated in excess of 1,840,000 miles of operation under ambient conditions ranging from monthly low temperatures of -8 C (18 F) at Fort Knox to monthly high temperatures of 35 C (95 F) at Fort Bliss. Two grade 15W- 40, MIL-L-2104D qualified lubricants were employed in the test, one product at each of the test ...

Since people are interested in Starship metals, here is a .

It is now clear that the total residual impurity content, and in particular oxygen and iron, seriously affects the low temperature toughness values. The effect of low temperatures on the mechanical properties of four nickel base alloys, K-Monel, Inconel-X, Rene'41, and Hastelloy B-40% CR, is shown in Fig. 1 5.

Science-fictional shibboleths - Charlie's Diary - Antipo

Science-fictional shibboleths By Charlie Stross Let's ignore, for the moment, the point that fiction is an exploration of human interior spaces, and that sometimes a spaceship or a princess is a metaphor; science fiction and fantasy are genres famous for their departure from the plane of mundanity, and usually a spaceship is just a form of ...

LeMay’s greatest gift was for orchestration. The effective conduct of large-scale air operations involved a multiplicity of factors: airfields, aircraft, ordnance, trained crews, mechanics, spare parts, fuel and lubricants, accurate weather forecasts, effective communications, up-to-date intelligence, base support, replacements, and on and on.

The Oil Drum | Will the decline in world oil supply be .

An Oil Drum reader wrote, asking the following question: Dear Oil Drum Editors, I have been reading quite a bit about peak oil recently. I get the impression (not based on data) that at some point there will be a quite steep decline in oil production/supply, and therefore we will see dramatic changes in how the world runs.

Scientists are using similar techniques in the Rocky Mountains to determine the distribution of endangered Bull trout and invasive Brook trout. eDNA is a highly sensitive method for detecting organisms in low abundance and is generally faster and more cost effective than traditional sampling methods. eDNA allows researchers to inexpensively ...

Ground-Coupled Natural Circulating Devices (Thermosiphons .

Compared to conventional ground heat exchangers that require a separate pump or other mechanical devices to circulate the heat transfer fluid, ground coupled thermosiphons or naturally circulating ground heat exchangers do not require additional equipment for fluid circulation in the loop. This might lead to a better overall efficiency and much simpler operation.
