Aviation History
1959
1959 - 2140.PDF
This year- Airliners on regular services are flying at heights where ambient temperatures can fall to less than —70JC. Fuel tanks and especially fuel lines are exposed for long periods to these sub-zero temperatures, and fuels approach the lower limit of ' pumpability '—beyond which heavier hydrocarbons solidify into a waxy mush AIR BP has conducted exhaustive tests on the characteristics of its fuels, proving that under operating conditions, full fluidity is maintained at these air temperatures. The Armstror. --Whitworth Argosy; Freighter Coach, Air Bus and Military Tranhert. . • first flew in 1959—on AIR &P fuel. Flight, 4 Sepumbt, 1959 The Caravelle; joined Air France and SAS in 1959—AIR BP services Caravelhs on many European routes. This year— We are nearer to the point where aviation will come face to face with the ' heat-barrier '. Fuel technologists are as concerned with the problems attendant on kinetic heating in hypersonic flight as are the designers of aircraft: at such elevated temperatures some hydrocarbons deteriorate, forming gum deposits to clog minutely calibrated orifices »nd close-tolerance assemblies. AIR BP research has proved that BP aviation fuels are already immune from these troubles at temperatures as high as 200 C. This year- More people are travelling more miles in more aircraft than ever before. More responsibility for the operators, more reliability required from every part of the air transport system: including aviation fuels. Dirt must be eliminated to prevent mechanical damage—water must be extracted to avoid fuel system icing. New multi-stage water separation systems developed by AIR BP have been in use for some time and can remove solids as small as 5 microns or better in diameter from fuel delivered to aircraft, and the simultaneous extraction of free water down to the last 30 parts per million by volume. * This year- Aircraft are faster, schedules are tighter, time on the ground more expensive. Time to turn round an airliner is of real importance as a factor in its utilisation, and here AIR BP development is again helping air operators. The new AIR BP superfuellers capable of delivering 10,000 gallons in 16 minutes, and hydrant systems delivering at up to 5000 gallons per minute, provide a service streamlined to the needs of the jet age.
