Innovative modification of fuel blends on the basis of the dynamic dissolution of combustible gases in a liquid hydrocarbon fuel (part three)

U.S. Air Force Research Laboratory (AFRL) and the National Research Council of Canada (NRC) conducted a joint test jet Dassault Falcon 20 to 100 per cent biofuel. It is reported by Jane's.

The tests were held on 29 October, but became aware of them until now. According to the publication, still aircraft, which have an alternative fuel, fueled with a mixture of conventional and biofuels (usually in the ratio of one to one).
According to Jane's, bio-branded ReadiJet been provided by the companies commissioned by the U.S. Air Force Applied Research Associates (ARA) and Chevron Lummus Global (CLG). Flight of the prototype lasted one hour. The report on the efficiency of the new bio-fuel will be published later.

In July 2012 the U.S. Air Force attack aircraft experienced A-10 Thunderbolt II on a mixture of ordinary and "alcoholic" fuel ATJ.

Until the end of 2012, the U.S. Air Force, which account for over 50 per cent of the total consumption of the Armed Forces of the United States consumption, plan to certify all aircraft and helicopters for the use of biofuels. By 2016, the consumption of conventional fuels in the Air Force planned to reduce by half.

In addition to the U.S. Air Force of the transition to biofuels developed for other types of U.S. forces. In mid-March, the Pentagon presented a "road map" energy forces. According to the draft, the U.S. military are going to use in the field of solar cells, as well as closed-loop system to minimize the difference in the amount of energy consumed and produced




The U.S. Air Force conducted the first test aircraft - attack aircraft A-10 Thunderbolt II - to "alcoholic" fuel, according to Defence Talk.
It is the fuel in the U.S. is also known by the acronym (ATJ, Alcohol To Jet). In trials in tanks attack aircraft was flooded with a mixture of ATJ fuel and standard jet fuel JP-8.

According to test pilot Major Olivia Elliott (Olivia Elliott), A-10 behaved in the air, as if it were filled with conventional fuels.

Tests A-10 conducted as part of the U.S. Air Force to transfer all aircraft on an alternative fuel.

ATJ is produced from sugars in the wood, paper, grass and other plant material containing a lot of fiber. Then, the obtained fermented sugars into alcohol, which then passes through the hydro-treating process.

The resulting oil can replace currently used standard jet fuel JP-8.
According to the Denver Post, the production of ATJ for the U.S. Air Force is engaged in a U.S. company Gevo. In 2011 she was awarded a contract for the supply of military 11000 gallons (41.6 liters thousands) ATJ, produced from iso-butanol.

According to the newspaper, flying A-10 for the "alcoholic" fuel took place on June 28 at Eglin Air Force Base, but became aware of it only now. Before flying A-10 ground tests passed with ATJ, which test the operation of aircraft engines.

Currently, the share of the Air Force for more than 50 percent of total fuel consumption by U.S. forces. The annual volume of fuel consumption of the air force is an average of 2.5 billion gallons.

Under the current program, the U.S. Air Force are going to the end of 2012 to complete the certification of all available aircraft and helicopters for the use of biofuels, by 2016 the military plans to reduce the consumption of conventional fuels by half.

By now fully completed the test aircraft for the opportunity to work on biofuels produced from coal and natural gas, and also from plant and animal fats.

This fuel is the common name HRJ (Hydro-processed Renewable Jet). In December 2011, the U.S. Department of Defense has purchased 450,000 gallons of biofuel plant, spending his $ 12 million.

The American military transport aircraft Boeing C-17 Globemaster III made its first flight on a mixture of conventional fuel grade JP-8 and biofuel, according to Defense Aerospace.

The tests took place at Edwards Air Force Base and the United States took place from 23 to 27 August 2010.

In the test was first used special blend consisting of 50 percent of JP-8, 25 per cent - of the fuel produced by processing of beef fat, and 25 per cent - of biofuel produced from recycled coal.

During the flight test, the mixture fuel is supplied first to one engine, then two, and so on. Thus, during the last test flight of a mixture of biofuel and JP-8 was applied to all engines transporter; C-17 is powered by four turbofan jet engines.

Earlier flights on biofuel in the United States have already committed attack aircraft A-10 Thunderbolt II fighter and the F/A-18 Super Hornet.

It should be noted that these aircraft flew in a mixture of 50 percent of JP-8, and the same amount of fuel derived from camelina, plants of the cabbage family, is not used in food. In flight, the C-17 fuel produced from coal and animal fat was used for the first time.

In the U.S., a program to transfer all aircraft to a new kind of fuel that will enable the military to save significant money on buying kerosene.

As expected, the Air Force is the largest consumer of fuel in the U.S., will transfer all its planes on biofuels by 2016, all military aircraft have to obtain a certificate of fitness for use of biofuels by 2012.

In November 2009, the U.S. Air Force began to fuel the creation of the Center for Aerospace Research. This center will develop an alternative fuel for the fighters, which in the long term will opt out of the use of traditional jet fuel in aircraft.

On the establishment of the center will spend about $ 2.5 million.
