Lift to drag ratio

Lift:Drag

• The amount of lift created by a wing or a vehicle.
• An aircraft has to have a certain lift:drag ratio in order to fly.
• The more weight the aircraft has the more lift is needed in order to fly. The larger the aircraft is the more drag it produces.
• The lift to drag ratio on a Boeing 747 is 17 and a Albatross has an L:D of 20

The viscosity of jet fuel

Jet-A1/Jet-A1

• The viscosity of aviation fuel is very important because the fuel will be flowing through pipes that can get to -20 degrees Celsius.
• The fuel must be have a relitivelty hight viscosity because the engine burns fuel quickly.
• The viscosity of Jet-A1/Jet-A1 fuel is 4.7704 mm2/second at -20 degrees Celsius. The density is 0.775 - 0.840g/cm3.
