The innovation would involve the use of refueling jets capable of meeting planes in the sky to provide top-up kerosene. Mid-flight refueling operations already exist and are sometimes used by military jets. Air Force One, the official plane of the US President, is capable of being refueled while in the air, as are some helicopters.  Under a system which makes use of refueling jets, researchers estimate passenger jets could carry less fuel on takeoff, then refuel once they reach an altitude of 33, feet (10, meters). Noise pollution would also be reduced, as airplanes make more noise the heavier they are at takeoff. Aircrafts at Helsinki Airport are refueled in a matter of minutes.  Kerosene suits planes because it as a suitably low freezing point, a high energy content and is relatively cheap. Kerosene is also available worldwide. “Commercial aircrafts are all refueled with Jet A-1 kerosene. There is also another airport in Helsinki from where aviation fuel is available, but it is meant for light aircrafts,” says Bergman.  The rates and speeds at which refueling happens at airports are sky-high compared to those at a gas station. A standard refueling for a continental flight departing from Helsinki-Vantaa lasts roughly between 15 and 20 minutes, during which tens of thousands of liters of fuel is pumped into the aircraft. “The standard speed at which an aircraft is refueled is liters per minute. Aircraft refuelling and de-fuelling are accompanied by attendant hazards which must be managed sufficiently for their mitigation to acceptable levels. The issues are much the same whether the fuel source is a tanker/bowser or a fuel hydrant system. Pressure refuelling is normal for multi crew transport aircraft and business jets but gravity refuelling of these types may be available as a backup system. The kerosene fuel used by turbine engine aircraft has a higher flash/ignition point than the.
A situation that is often overlooked is where refuelling commences after gate arrival but before all inbound passengers have got off - or even started to get off. Accumulation of a surface static charge may occur on either an aircraft or its fuelling vehicle under certain conditions. Sector News. The idea of tanker planes began to develop in Russia at the beginning of the s under the initiative of the famous aircraft designer Vladimir Sergeyevich Vakhmistrov. GND : Civilian aircraft : Commercial and private airplanes are not designed for air-to-air refueling.
