What is the only Fsii additive approved for turbine fuels?
Innospec’s FSII -41 ice inhibitor is based on Di-Ethylene Glycol Monomethyl Ether (DiEGME) chemistry, the preferred solution for today’s market. The additive is suitable for use in either aviation turbine fuel (jet fuel ) or aviation gasoline, subject to specification requirements and approvals.
What chemicals are in jet fuel?
Chemical composition Aviation fuels consist of blends of over two thousand chemicals, primarily hydrocarbons (paraffins, olefins, naphthenes, and aromatics), additives such as antioxidants and metal deactivators, biocides, static reducers, icing inhibitors, corrosion inhibitors, and impurities.
What are the different types of aircraft fuels used in the aviation industry?
In general aviation, there are two main aircraft fuel types, which are AVGAS and Jet Fuel.
What are the two main methods of fueling aircraft?
There are two common ways of supplying fuel to the aircraft from the transfer fuel line, refuelers or hydrant carts.
What are common additives for Jet A fuel?
Types of jet fuel additives
- Tetra-ethyl lead. To improve the anti-knock characteristics of avgas, tetra-ethyl lead is added.
- Antioxidants (gum inhibitors)
- Metal deactivator.
- Corrosion inhibitors.
- Fuel system icing inhibitors.
- Static dissipater additives.
What is Jet A with Prist?
“ Prist is a trade name for an aviation fuel system icing inhibitor, diethylene glycol monomethyl ether. This is an approved additive, which may be added to jet fuel— Jet A, A-1, B—to prevent free water from forming ice and potentially blocking engine filters,” Clarke said. Jet A-1 doesn’t hold sway everywhere.
Is jet fuel a kerosene?
Jet fuel ( Jet A-1 type aviation fuel, also called JP-1A) is used globally in the turbine engines ( jet engines, turboprops) in civil aviation. This is a carefully refined, light petroleum. The fuel type is kerosene.
What octane is jet fuel?
The octane ratings of AVGAS, a gasoline -based fuel, are usually either 91 or 100 (lean mixture) and 96 or 130 (rich mixture). The octane rating of jet fuel is much lower, around 15 – this is much more like automotive diesel and thus much more resistant to detonating due to sparks or compression.
What is the difference between jet fuel and kerosene?
Depending on the grade, jet fuel is basically highly refined kerosene. The kerosene and paraffin difference is that the paraffin is a component of kerosene, and when petroleum refining is complete, it remains as a waxy residue.
Which fuel is used in aircraft?
Aviation kerosene, also known as QAV-1, is the fuel used by airplanes and helicopters equipped with turbine engines, such as pure jet, turboprops, or turbofans.
Why is kerosene used as jet fuel?
In addition to a lower freezing point, kerosene has a higher flash point than gasoline. With its higher flash point, kerosene offers higher octane ratings to achieve greater power and efficiency when compared to its gasoline counterpart. In fact, this is the main reason kerosene fuel is used in airplanes.
What color is jet fuel?
Jet fuel is a type of aviation fuel designed for use in aircraft powered by gas-turbine engines. It is clear to straw-colored in appearance.
Where is fuel tank in aircraft?
On passenger planes, fuel tanks are often integrated into the wings, and when there are also tanks inside the body of the aircraft, the wing tanks are used preferentially. The placement reduces the stress on the wings during takeoff and flight, by putting the heavy fuel directly inside the source of lift.
Why is there unusable fuel in an aircraft?
Fuel Tanks Must Be Able to Supply Minimum Fuel Pressure and Flow. For both gravity fed and pump systems, there has to be enough fuel in the tank to supply the required pressure as outlined above. Unusable fuel is partially there to ensure that there is enough pressure for the usable fuel to comply with this regulation.
Why is jet fuel so cheap?
The fuel that powers passenger planes is normally among the most expensive oil products, but in a sign of the times the coronavirus has turned it into a blending component for typically cheaper shipping fuel. Higher than normal amounts of diesel and vacuum gasoil are also finding their way into shipping fuel.
