Characteristics

Characteristics
The qualities of this Repsol fuel make it perfect for jet engine turbines in civil aviation. It is a kerosene that comes from the distillation of crude oil, which is the raw material of the refining industry.
Its primary function is to supply power to the aircraft. The key parameters are its energy content and the quality of combustion
It's colorless or slightly yellow, with an approximate average density of 6.7 lb/US gallon (0.8 kg/L), and it can be flammable at temperatures greater than 100.4°F (38°C) in the presence of a flame or spark. If there were only one thing worth mentioning, it'd be the great heat potential that enables maximum possible energy at minimum weight. It also has an excellent level of cold resistance with very low crystallization point temperatures, since at the altitudes at which the aircraft fly temperatures are very low. 
Great product stability, to ensure that it is not affected by oxidation processes, as well as a high degree of thermal stability. In addition to providing energy, the fuel is also used as the hydraulic fluid in the engine control systems and as a coolant for certain fuel system components.

Applications

The use of JET A-1 is determined by the type of aircraft engine. In current models, this fuel is used not only to provide energy, but also as a lubricant and as a heat exchanger to cool:
  • The motor oil,
  • the hydraulic circuit, and
  • the air conditioning equipment.
JET A-1 is a liquid fuel that is injected continuously into a combustion chamber in which a constant current of gases is produced at high pressure and temperature. This stream of gas is what generates the jet reaction that propels the aircraft.
Today's high-performance turbojets compress the air up to three and four times more than piston-based engines. Compressing the air, prior to mixing it with the fuel and combustion, is one of the factors that has the most impact on fuel economy.

Quality

The quality of the product is checked at the Repsol refineries, renowned for their stellar quality, throughout the entire JET A-1 fuel manufacturing process. Continuous filtration of water and solid particles guarantees a fuel with a high level of purity, the main purpose of which is to maintain the product's qualities.
Our methodology for quality loss prevention is based on avoiding the accumulation of water, microbiological contamination, and solid particles. 
At each stage in the JET A-1 production process, tests are run to determine the absence of these elements, and the fuel goes through different filtration processes. This ensures that the fuel supplied to the aircraft complies with all quality standards.

Turbines

Turbines
JET A-1 is used in aircraft propelled by turbine engines. In these, unlike in the spark-ignition engines, there are no pistons or rods that convert longitudinal movement into circular. On the contrary, they consist of a rotor, with small blades, that is moved by the combustion gases.
Turbines convert the kinetic energy of a fluid into movement, into mechanical energy by means of the fluid movement towards the rotors. The hot compressed gases leave the engine at high speed, generating the force or impulse that moves the aircraft forward. The turbine has three sections, each of which having a different function:the compression section, the combustion section, and the turbine section.
  • The Compression Section: introduces and compresses ambient air and delivers compressed air to the combustion section.
  • The Combustion Section: once the compression stage has been completed, the compressed air reaches the combustion chamber, where it mixes with the fuel that is introduced into the chamber by means of a set of injectors. This is when combustion occurs and the hot gases that are created leave through the nozzle located at the back of the engine. The exhaust flow is what produces the impulse that moves the aircraft. 
  • The Turbine Section: the rotors are connected to the compressor by an axle. The impulse of the combustion gases in movement against the rotor blades moves the turbine and, as a result, the compressor. 

Drums

JET A1 in drums is more than just a fuel. It is a product created to be easy to use and handle, offering the customer a series of services, such as personalized attention, flexibility, technical assistance, etc. These services, along with the product’s quality guarantee, provide you with convenience, savings, and freedom of movement. Repsol also takes care of the environment by treating the drum after its use.
JET A-1 will make your life easier, and here's how:
  • We transport the drums to wherever you need them, the flexibility of the process is fantastic.
  • We reduce costs by eliminating transport, access and filling fees, and airport access insurance, which means we offer very economic prices.
  • We're extremely efficient in all our activities. The proof in this is that facilities will not depend on airport supply windows.
  • We provide single-use drums, sealed, specific for aviation, approved, certified according to the ISO 9001 standard and guaranteed by Repsol. Long-lasting. 
  • Our drums have an expiry date of one year from filling for both products.
  • Environmentally friendly. We have a service for collecting drums directly from the facilities. For orders of more than eight drums, the used drums are collected to then be processed as waste. And at no additional cost.
  • We make storage easier, by not requiring any maintenance provided they are sealed.
  • Technical advantages. We offer technical assistance, training courses, advice on accessories and technical instructions for handling drums.
Accessories recommended by Repsol for optimal performance of your turbines: 
  • Manual transfer pump with own consumption meter, filter, hose and aviation nozzle.
  • 12-24 v electrical transfer pump with own consumption meter, filter, hose, and aviation nozzle.
  • Drum holders.
  • Drum trucks.
  • Drum tanks.
  • Anti-spillage material
